102. Receiving, Moving and Storing Systems and Batteries
102.1 Shipping Damage
LSN inverter systems and batteries are normally shipped separately.
Carefully inspect all cartons upon receipt for evidence of shipping damage. Notify carrier immediately of leaking or damaged cartons for possible concealed damage.
All LSN electronics cabinet cartons are shipped with tip and vibration indicators. Refuse all shipments in which the tip or vibration indicators have been activated.
102.2 Moving Units and Batteries
CAUTION: Batteries and LSN Electronics cabinets are very heavy. Proper equipment should always be used to move batteries and units to avoid damage and personal injury.
WARNINGS: · ALWAYS WEAR PERSONAL EYE PROTECTION WHEN WORKING WITH BATTERIES – SEE PAGE 10 · Batteries contain liquid caustic or acid electrolytes which CAN CAUSE SEVERE BURNS.
Care must be taken when moving batteries to avoid tipping and spillage of electrolyte material. In case of accidental spill. ANTIDOTE: · EYES: Flush immediately with flowing water for at least 15 minutes. Seek medical attention. · EXTERNAL: Flush immediately with water. Seek medical attention.
102.3 Temporary Storage of Units and Batteries
For temporary storage of LSN inverter systems and batteries prior to installation, select a clean, cool, dry location with normal ventilation for human habitation and level floors.
CAUTION: Batteries and LSN Electronics cabinets are very heavy. Check to assure that the floor in the temporary storage area is capable of safely bearing the load.
IMPORTANT: Lengthy storage of batteries will cause irreversible damage to the cells. Failure to connect LSN inverter system batteries to an energized charging circuit within 90 days from the date of shipment will void the battery warranty.
Storage Temperature:
Store all batteries at 0° to +40° C (32° to +104° F). Batteries will have a longer shelf life if stored at 25° C (77° F). The LSN electronics and battery cabinets may be stored at -20° to +60° C (-4° to +140° F).
Ventilation:
The air around the unit must be clean, dust-free, and free of corrosive chemicals or other contaminants. Do not place the LSN inverter system or batteries in a sealed room or container.
DANGER: EXPLOSIVE – CAN CAUSE BLINDNESS OR OTHER SEVERE INJURIES. Every type of battery can produce hydrogen gas, even sealed, maintenance-free batteries. The gas is vented through the vent caps and into the air. Do not allow smoking, sparks, or flames in battery storage location because hydrogen is concentrated under the vent cap of each cell of the battery. Hydrogen is highly explosive, and is hard to detect because it is colorless, odorless, and lighter than air.

103. Installation Requirements
103.1 Operating Environment
Install the LSN inverter system in a clean, cool, dry place with normal ventilation for human habitation and level floors.
CAUTION: Batteries and LSN Electronics cabinets are very heavy. Check to assure that the floor is capable of safely bearing the load.
Operating Temperature:
LSN inverter Systems are UL Listed for 20° to 30° C (+ 68° to +86° F) operation. The LSN Inverter System has a designed operating range of 0° to +40° C (+32° to +104° F) at up to 95% relative humidity. Installation in environments at the temperature extremes of the designed operating range may effect unit performance or reduce service life. Battery performance and service life is maximized if the operating temperature is maintained at 25° C (77° F) .
Ventilation:
The air around the unit must be clean, dust-free, and free of corrosive chemicals or other contaminants. Do not place the LSN inverter system or batteries in a sealed room or container.
Batteries:
The temperature should be near 25° C (77° F) for optimum battery performance. Temperature Effect On Performance: Batteries will be less efficient at temperatures below 18° C (65° F), and high temperatures will reduce battery life. Typically, at 35° C (95° F), battery life will be half of what it would be at normal temperature of 25° C (77° F). At 45° C (113° F), battery life will be one-fourth of normal.
WARNING: Every type of battery can produce hydrogen gas, even sealed, maintenance-free batteries. The gas is vented through the vent caps and into the air, mainly when the unit is charging the batteries. The batteries produce the most hydrogen when maximum voltage is present in fully charged batteries. The amount of current that the charger supplies to the batteries (not the battery ampere-hour) determines how much hydrogen is produced. Do not allow smoking, sparks, or flames in battery storage location because hydrogen is concentrated under the vent cap of each cell of the battery. Hydrogen is highly explosive, and is hard to detect because it is colorless, odorless, and lighter than air.
! CAUTION
NEVER INSTALL BATTERIES IN A SEALED ROOM OR ENCLOSURE
IMPORTANT: Lengthy storage of batteries will cause irreversible damage to the cells.
Failure to connect LSN inverter system batteries to an energized charging circuit within 90 days from the date of shipment will void the battery warranty.
103.2 High Altitude Operation:
The maximum operating temperature drops 1° Celsius per 300 meters (2° F per 1000 feet) above sea level. Maximum elevation is 3000 meters (10,000 feet).

Installing the Batteries and DC Wiring
Important Safety Precautions
The installer must take these precautions:
1. Wear protective clothing, eye-wear, rubber gloves and boots. Batteries contain corrosive acids or caustic alkalis and toxic materials and can rupture or leak if mistreated. Remove rings and metal wristwatches or other metal objects and jewelry. Don’t carry metal objects in pockets where the objects can fall onto the batteries or into the LSN inverter system or battery cabinet.
2. Tools must have insulated handles so that they will not short battery terminals. Do not allow a tool to short a battery terminal to another battery terminal or to the cabinet at any time. Do not lay tools or metal parts on top of the batteries, and do not lay any objects where they could fall onto the batteries or into the cabinet.
3. Install the batteries as shown on the battery wiring diagram provided in this manual or with the battery cable kit. When connecting cables, never allow a cable to short across a battery’s terminals, the string of batteries, or to the cabinet.
4. Align the cables on the battery terminals so that the cable lug will not contact any part of the cabinet even if the battery is moved. Keep the cable away from any sharp metal edges.
5. Install the battery cables so they cannot be pinched by the battery cabinet or the LSN inverter system doors.
6. External battery cabinet chassis ground (or earth) must be connected to the LSN inverter system unit’s chassis ground (or earth). The ground conductor must be insulated. If you use conduit, this ground conductor must be routed in the same conduit as the battery conductors.
7. Where conductors may be exposed to physical damage, protect conductors in accordance with NEC requirements.
8. Full voltage and current are always present at the battery terminals. The batteries used in this system can produce dangerous voltages, extremely high currents, and possible risk of electric shock. Batteries may cause severe injury if the terminals are shorted together or to ground (earth). Be extremely careful to avoid electric shock and burns caused by contacting battery terminals or shorting terminals during battery installation. Do not touch uninsulated battery terminals.
9. A qualified electrician who is familiar with battery systems and required precautions must install and service the batteries. Any battery used with this unit shall comply with the applicable requirements for batteries in the standard for emergency lighting and power equipment, UL 924. Cabinets are designed to be used with, and batteries must be replaced by identical cells or a Dual-Lite approved equivalent. If using substitute batteries not supplied by Dual-Lite, the unit’s UL listing will be void, and the equipment may fail to perform properly. The installation must conform to national and local codes as well. Keep unauthorized personnel away from batteries.

105.1 Tools
The following tools are required to install the system batteries. Other tools may be necessary if optional batteries have been ordered. CAUTION: Always use insulated tools for battery installation. Always torque to the manufacturer’s recommendations.

AC Connections

CAUTION A. All LSN inverter system units contain hazardous AC and DC voltages. Because of these voltages, a qualified
electrician must install the LSN inverter system, AC line service, and batteries. The electrician must install the AC line service according to local, state and NEC codes and must be familiar with batteries and battery installation.
B. Before installing, maintaining, or servicing the unit, always remove or shut off all sources of AC and DC power and shut off the LSN inverter system. Disconnect AC line input at the service panel and turn off the Main DC Switch, the Main AC Switch, and the Master Switch to make sure the unit will not supply output voltage.
C. Whenever AC and/or DC voltage is applied, there will be AC voltage inside the LSN inverter system unit; the unit can supply power from AC line or from its batteries. To avoid equipment damage or personal injury, always assume that there may be voltage inside the LSN inverter system.
D. Remove rings, watches, and other jewelry before installing the AC wiring. Always wear protective clothing and eye protection and use insulated tools when working near batteries. Whenever servicing an energized unit with the inside panel open, electric shock is possible; follow all local safety codes. TEST BEFORE TOUCHING!
E. Before installing an external bypass switch, make sure that both the bypass switch and the AC disconnect switch are off.
F. To reduce the risk of fire or electric shock, install the LSN inverter system and the batteries in a temperaturecontrolled and humidity-controlled indoor area free of conductive contaminants. See Section 103 for operating environment specifications.
Preparations
1. Open the circuit breaker access door. Make sure all breakers are in the off position.
2. Make sure the LSN inverter system input and output voltages are correct for the particular application. Remember that the LSN system provides single- phase power only.
3. The input circuit breaker in the input service panel provides the means for disconnecting AC to the LSN inverter system. If using a bypass switch, the bypass enclosure also includes a separate AC Disconnect switch. Only authorized persons shall be able to disconnect AC to the unit. (See NEC 700-20 and 700-21.) Bypass switches with AC Disconnect have handles that can accept a lock to restrict control to authorized persons. If using the input circuit breaker to disconnect AC, make sure that only authorized persons have control of the circuit breaker panel to meet the requirements of NEC 700-20.
4. If installing a bypass switch, use the installation and wiring instructions supplied with the bypass switch. NOTE: Systems not using a bypass switch may have optional output circuit breakers and/or a normally off relay.
CAUTION To prevent electrical shock or equipment damage, for all units, with and without a bypass switch, make sure the Master Switch, the Main AC Switch, the Main DC Switch on the inverter and the bypass switch (if applicable), all output circuit breakers, and the AC input at the service panel are all off before making AC connections to the LSN inverter system.

109. Maintenance Bypass Switch Phase Check

If you are not using a bypass switch with the LSN inverter system, the phase check is not necessary, so you can skip this section and go directly to Section 110 to complete the system start-up. If the LSN unit does have a bypass switch, complete the following phase check once you have made all of the terminal strip connections and installed the batteries.

! CAUTION: Before you switch the bypass switch from “UPS” to “AC Line,” make sure you follow the steps below to check for correct operation.

1. Make sure the main circuit breaker at the load service panel is off, or make sure the connected loads (protected equipment) cannot receive power from the LSN inverter system. Turn the bypass switch to the “OFF” position. At the AC service panel, apply power to the LSN system and the bypass switch. Turn the LSN Master ON/OFF Switch to the “ON” position. Turn the bypass switch to the “ON” position.

2. Press the precharge switch for ten seconds. Release the precharge switch and immediately turn the LSN Main DC Switch to the “ON” position.

3. Turn the Main AC Switch inside the LSN system to the “ON” position. The loads (protected equipment) should still be off at this time. After a short startup, the READY LED and AC-ON LED will illuminate. The LSN inverter system is ready to supply output power.

4. Make sure the voltage from the LSN system to the connected loads is close to the voltage from AC line to the bypass switch. (There may be slight differences.) To measure this, use an AC voltmeter check the voltage

between the following points on the bypass switch terminal strip. (See the terminal strip label). Record the

voltages below.

AC from LSN Output

AC Line Input

(60 Hz 208 or 240VAC only) 7 to 8_____VAC

11 to 12_____VAC

(60 Hz 208 or 240VAC only) 6 to 8_____VAC

10 to 12_____VAC

(All other voltages)

7 to 8_____VAC

11 to 12 _____VAC

The voltages recorded in the first column should be similar to the voltages in the second column. The voltages may vary slightly. If the voltage readings vary more than a few volts, shut down AC line and the LSN system. Check all connections at the terminal strip, and correct any wiring problems. If help is required, contact Dual-Lite’s Technical Support Center at 1-800-848-6439.

Important: If the AC Input voltage is 208 volts, you will normally measure 88VAC between output terminals 6 and
8. Never connect any 120-volt load to the 88-volt terminals.

5. If a Break-Before-Make type bypass switch is being used, proceed to step 8.

If a Make-Before-Break bypass switch is being used, make sure the AC voltages from the LSN system output and the AC line input are in phase. To do this, measure the AC voltage between the following points on the bypass switch terminal strip. These measurements should not be more than 100VAC; if measurements exceed 100VAC, contact Dual-Lite’s Technical Support Center at 1-800-848-6439.

(60 Hz 208 or 240 V only)

8 to 12VAC (All other voltages) 7 to 11VAC

6. Measure the AC voltage between the following points on the bypass switch terminal strip. This reading should not exceed 1VAC; if measurements exceed 1VAC, contact Dual-Lite’s Technical Support Center at 1-800-848-6439.

(60 Hz 208 V or 240 V)

6 to 10_____VAC

(60 Hz 120 V or 50 Hz 220/230/240 VAC) 8 to 12_____VAC

21

!

CAUTION: If a Make Before-Break type bypass switch is being used, equipment will be

damaged

if the switch position is changed while AC line voltage is applied and the LSN system

is turned off or operating in inverter (DC) mode. Make sure the LSN system is running on line (AC mode)

and supplying output voltage before changing the bypass switch position. See the instructions supplied with

your bypass switch.

7. Turn the bypass switch to the “LINE” position. Using an AC voltmeter, verify the voltage to your protected

equipment load is correct. Voltage can be verified at the Load Distribution Panel.

8. Turn the bypass switch to the “UPS” position and measure the voltage to your protected equipment load once more (at the Load Distribution Panel). Verify the voltage is correct.

9. If all readings during the voltage and phase check are acceptable, reattach the bypass switch cover. Tighten the retaining screws securely. Proceed to Section 110 to complete the system start-up.

110. Start-Up Procedure
FACTORY START UP: A Factory Start Up is offered as a service option with this unit. Please contact Dual-Lite’s Technical Support Center.
IMPORTANT: The LSN inverter system is a sophisticated electronic back-up power supply. Care must be taken to follow the steps below in their exact sequence. Failure to do so will result in erroneous alarm messages and possible equipment failure.
CAUTION: Familiarize yourself with the shut down procedure in section 300.1 before proceeding with the Start Up.
1. Turn on the input circuit breaker in the building service panel serving as the AC disconnect to the LSN system and check for proper voltage and phasing on the AC Input terminal block.
2. Turn on all output circuit breakers in the external Load Distribution Panel. 3. Close and lock the main cabinet door to the LSN Inverter cabinet. 4. Open the LSN system Circuit Breaker access door. 5. Turn on the output circuit breakers (if any). 6. Turn on the LSN Master On/Off Switch. Caution: This is a locking toggle type switch. Pull it out towards

Turn on the Main AC switch. 10. After approximately five seconds, the system should turn on, the lighting loads should be energized,
the front panel “AC-ON” and “READY” LEDs should illuminate, and the system LCD display will begin to scroll the system parameters. 11. Depending on the state of charge of the batteries, the front panel Charging LED may illuminate.
111. System Verification
At this point, the connected load should be energized, the “Ready” and “AC On” LEDs should be lit, and the display is scrolling through 18 operating messages. Wait 2 minutes while the system completes its final set up, and then look at the various messages and make sure they are within expected limits. If any alarms sound, go to section 205 for further instructions. If you need assistance, call Dual-Lite’s Technical Support Center at 800-848-6439. If no alarms sound, perform the following inverter test to verify its operation: Once the “Ready” LED is illuminated, simulate a power failure by opening the AC input circuit breaker. The inverter and the cooling fans will begin operating. All connected loads should be energized and operational, HID fixtures should not “wink-out”. Allow the inverter to run for several minutes or until satisfied with its operation. Close the AC input breaker to end the test and return the unit to standby mode. Note: It will take a few seconds for the unit to re-synchronize with the input line. The inverter will turn off when synchronization is achieved.

202. System Self-Diagnostics
Self-testing/self-diagnostic electronics perform continuous testing of subsystems, insuring performance to prescribed operating parameters. Operation outside of prescribed limits or system malfunctions will result in an alarm indication on the system’s user interface display panel. Depending on the type of alert, the panel alarm indication may be visual or audiovisual. User- programmable discharge tests are automatically performed on a monthly and annual basis. Date, time and duration of these tests can be programmed to meet state, local authority and individual requirements. All testing events are automatically logged in memory and can be displayed on the user interface panel.

203. System Auto Testing

The LSN inverter system automatically performs three sophisticated, microprocessor-controlled system discharge tests; a weekly test, a monthly test and an annual test. The following parameters affect these tests:

Weekly test

Monthly Test

Annual Test

· Schedule (264)

· Time of day for monthly test (73)

· Time of day for annual test (185)

· Date for monthly test (127)

· Date for annual test (184)

· Monthly test duration (129)

· Annual test duration (129)

· Monthly reschedule interval (183)

· Annual reschedule interval (186)

203.1 Weekly Test
Every week (at a time and date specified in parameter 264) the system will automatically operate the inverter for one minute. During this test, the system will monitor inverter output and connected load. The unit automatically records
the results of the test in parameter 26, which can be displayed from the user interface panel.

203.2 Monthly Test
Every month (or at the interval specified in parameter 183) the LSN Inverter System automatically performs a discharge test to check battery capacity and emergency inverter operation. The duration of the monthly test cycle is
controlled by parameter 129, set at the factory for 5 minutes. The unit automatically records the results of the test in
parameter 26, which can be displayed from the user interface panel.

203.4 Annual Test
Once a year, the unit automatically performs a battery exercise cycle/discharge test by running the unit in emergency mode for 90 minutes. It is recommended that it be scheduled at a time when the area protected by the LSN system will be unoccupied for a full 48 hours to allow the batteries time to recover to full capacity. The date on which the annual test takes place is stored in parameter 184 .

Extended Power Outages

During extended power outages, the LSN inverter system will provide power to all connected loads for its full rated discharge time. NOTE: During emergency operation of the LSN system, parameter 9 allows the user to determine how many minutes of runtime remain in the normal discharge period. At a set number of minutes prior to the end of the runtime (factory default setting is 30 minutes), the unit will sound a “Low Runtime” alarm. The unit may also simultaneously sound a “Near Low Battery” alarm. When either of these alarms occur, an orderly shutdown of any non-emergency equipment that may be connected to the system should be conducted in order to allow the inverter to operate critical emergency equipment for a longer period of time. Following the normal discharge period, the unit will continue to operate normally until battery capacity reaches a pre-set disconnect limit. At this point, the inverter will automatically disconnect inverter AC output power to the load. The unit’s electronic controls will remain powered by the system batteries until the batteries reach a second pre-set low limit at which point the unit will shut down completely to prevent deep discharge damage to the unit batteries.

Maintenance

Safe Shut Down Procedure
CAUTION To avoid possible equipment damage or personal injury, assume that there is AC voltage present inside the LSN inverter system unit any time AC input power or DC battery voltage is applied. The inverter is capable of providing output voltage from the batteries even when there is no AC input line voltage. When AC input voltage is present, the unit can provide output voltage even when the batteries are disconnected.
AC AND DC VOLTAGES WILL BE PRESENT INSIDE THE UNIT UNTIL LINE AC IS DISCONNECTED AND ALL INTERNAL SWITCHES ARE TURNED OFF.
Do not touch components inside the unit. DC voltage is always present at the batteries and battery cables.
If an external bypass switch is not used, turn off all connected equipment (loads) at their source and proceed to “Final Shut Down Procedure” below.
A. Bypass Switch Disconnect
If the unit utilizes a bypass switch, check the label to determine whether it is Break-Before-Make or Make-BeforeBreak. Follow the instructions for the type of switch identified:
Break-Before-Make: If a Break-Before-Make (BBM) external bypass switch is used, the switch will temporarily break input power as it switches from emergency inverter power to utility power (LINE) or back to CIS power. 1. Shut down all connected equipment (loads) 2. Turn the bypass switch to the LINE position. 3. If necessary, restart connected equipment.
Make-Before-Break: If a Make-Before-Break (MBB) bypass switch is used. 1. Make sure the AC Line light is on 2. Make sure the “Emergency Power” light on the user interface panel is off. 3. The LSN system must be providing utility AC pass-through to the connected equipment. CAUTION: If a Make-Before-Break bypass switch is used, equipment will be damaged if the switch position is changed when line is applied and the LSN system is operating in the “Off” or “On” (Emergency Battery Operation) Mode. See the instructions packed with the bypass switch. 4. Turn the bypass switch to the LINE position.
B. Final Shut Down Procedure
1. Open the unit’s front door. 2. Turn off the Master Switch, the Main DC Switch, the Main AC Switch and any Output Circuit Breakers. CAUTION: HAZARDOUS ENERGY IS STORED IN CAPACITORS INSIDE THE LSN UNIT. AFTER TURNING OFF SWITCHES, ALLOW 5 MINUTES FOR CAPACITORS TO DISCHARGE BEFORE ATTEMPTING ANY SERVICE PROCEDURES. 3. If the service technician does not need to access the inside of the unit, close and lock the unit’s front door. 4. If the unit will be shut off for an extended period of time, recharge the batteries every 60 to 90 days. CAUTION: The batteries will be damaged and the warranty voided if not routinely recharged.
NOTE: To turn power back on, follow the “System Startup Procedure” outlined in Section 110. Be sure to complete all of the steps to assure the unit will operate properly.

300.4 Battery Maintenance and Replacement
This section provides precautions for qualified service personnel working with unit batteries. No user serviceable parts are within the system’s cabinets

Important Safety Precautions

The service technician must take these precautions:
1. Wear protective clothing, eye-wear, rubber gloves and boots. Batteries contain corrosive acids or caustic alkalis and toxic materials and can rupture or leak if mistreated. Remove rings and metal wristwatches or other metal objects and jewelry. Don’t carry metal objects in pockets where the objects can fall onto the batteries or into the LSN inverter system or battery cabinet.
2. Tools must have insulated handles so that they will not short battery terminals. Do not allow a tool to short a battery terminal to another battery terminal or to the cabinet at any time. Do not lay tools or metal parts on top of the batteries, and do not lay any objects where they could fall onto the batteries or into the cabinet.
3. Install the batteries as shown on the battery wiring diagram provided in this manual or with the battery cable kit. When connecting cables, never allow a cable to short across a battery’s terminals, the string of batteries, or to the cabinet.
4. Align the cables on the battery terminals so that the cable lug will not contact any part of the cabinet even if the battery is moved. Keep the cable away from any sharp metal edges.
5. Install the battery cables so they cannot be pinched by the battery cabinet or the LSN inverter system doors.
6. External battery cabinet chassis ground (or earth) must be connected to the LSN inverter system unit’s chassis ground (or earth). The ground conductor must be insulated. If you use conduit, this ground conductor must be routed in the same conduit as the battery conductors.
7. Where conductors may be exposed to physical damage, protect conductors in accordance with NEC requirements.
8. If replacing batteries or repairing battery connections, follow the procedure in this manual to shut down the LSN inverter system and remove both AC and DC input power.
9. Full voltage and current are always present at the battery terminals. The batteries used in this system can produce dangerous voltages, extremely high currents, and possible risk of electric shock. Batteries may cause severe injury if the terminals are shorted together or to ground (earth). Be extremely careful to avoid electric shock and burns caused by contacting battery terminals or shorting terminals during battery installation. Do not touch uninsulated battery terminals.
10. A qualified electrician who is familiar with battery systems and required precautions must install and service the batteries. Any battery used with this unit shall comply with the applicable requirements for batteries in the standard for emergency lighting and power equipment, UL 924. Cabinets are designed to be used with, and batteries must be replaced by identical cells or a Dual-Lite approved equivalent. If using substitute batteries not supplied by Dual-Lite, the unit’s UL listing will be void, and the equipment may fail to perform properly. The installation must conform to national and local codes as well. Keep unauthorized personnel away from batteries.
37

CAUTION: A battery can present a risk of electrical shock and high short circuit current. Battery replacement should only be performed by qualified service personnel familiar with battery systems. All safety precautions outlined at the beginning of this section must be observed when servicing, maintaining or replacing batteries
Routine Battery Inspection and Maintenance
Sealed Lead-Calcium Batteries (Includes Type S and Type G batteries) Lead- Calcium cells are the most common type of battery used today in standby equipment. By design it is as maintenance free as a battery can be. Coupled with the diagnostic and self-testing capabilities of the LSN system, these batteries provide one of the most reliable and carefree inverter systems available today. It is recommended, however, that some simple steps be taken to increase system life and maximize reliability:
· If system is installed in a remote area where the system’s alarms may not be heard, it is recommended that the system be checked weekly for alarm conditions,
· A quarterly visual check of the batteries should be conducted to look for deformities in the cases and terminal corrosion. Any defective batteries should be replaced. All corroded terminals, regardless how slight, are to be cleaned and retightened at once to prevent failure of the entire battery bank.
· Once a year, all battery connections should be checked for tightness and re- torqued if necessary. Torque specifications can be found on the battery label.
Nickel-Cadmium Batteries Used in harsher environments, the wet nickel cadmium battery is designed for a 25-year life. When properly maintained it will give years of reliable performance. Care must to be taken to maintain adequate electrolyte levels and terminal cleanliness. Use only distilled water when necessary. Never use any kind of acid to refill the battery, serious damage and injury may occur.
The same frequency and procedures as listed above for the lead-calcium batteries should be followed.
If you have any questions, contact Dual Lite’s Technical Support Center at 1-800-848-6439. Please dispose of all batteries properly.
Battery Replacement Procedure
WARNING: Always use the same quantity and type of battery as replacements. Substituting batteries not supplied by Dual-Lite will void the UL listing of the system and may cause equipment failure. To ensure the superior performance of your LSN inverter system and to maintain proper charger operation, replace spent batteries only with Dual-Lite cells having the same part number, voltage and ampere-hour rating as the original batteries.
1. Follow the proper shut down procedure as described in Section 300.1.
2. Remove battery cabinet fuses and test them for continuity. Faulty fuses will prevent batteries from charging and render the battery bank useless during a power outage.
3. Break down the battery bank beginning with the intercell connectors. These cables tie the batteries installed on the same shelf together.
4. Next remove the inter-tier cables. These cables connect the batteries located on different shelves together.
38

5. Remove the batteries from the cabinet. Batteries can be very heavy, use proper lifting methods when removing battery.
6. Install new batteries following the instructions outlined in Section 105.3.
Battery Disposal
WARNINGS: Do not dispose of batteries in a fire, the batteries could explode. Do not open or mutilate batteries. Released electrolyte is highly toxic and harmful to the skin and eyes. CAUTION: Batteries contain lead. Many state and local governments have regulations about used battery disposal. Please dispose of the batteries properly. For help, contact the Dual-Lite Technical Support Center.
301. Warranty Information
