SAVE THESE INSTRUCTIONS
IMPORTANT ! – PLEASE TAKE NOTE BEFORE THE INSTALLATION:
You must determine how the connected emergency lighting fixtures are to operate; normally-on (unswitched and always energized), normally-off (only energized during a power failure), or switched on/off. Wire according to the appropriate wiring diagram given below. Consult factory for special wiring diagrams.
Ensure that ALL combined/connected Emergency lighting loads OVER this product’s maximum emergency output rating (250 VA or 185 VA, depending on the model) are capable of being dimmed down to a power output of 10% from an industry standard 0-10V source.
ELI-S-250 WILL ONLY deliver 250 VA and the ELI-S-185 WILL ONLY deliver 185 VA into the lighting load. This is accomplished by automatically dimming the connected emergency lighting loads down to the products output power rating.
THIS PRODUCT INCLUDES RECHARGEABLE LEAD-ACID BATTERIES.
THE BATTERIES MUST BE RECYCLED OR DISPOSED OF PROPERLY.

MODEL SPECIFIC OUTPUT RATINGS

Model| Input Voltage| Output Voltage (Autos elect)| Emergency Output Power| Max Connected **AC Load*| Emergency Run Time**
---|---|---|---|---|---
ELI-S-250| 120/277Vac| 120/277Vac| 250 VA| 800 VA| Minimum of 90 minutes
ELI-S-185| 120/277Vac| 120/277Vac| 185 VA| 800 VA| Minimum of 120 minutes

NOTE: AC Input Power to an LED or Fluorescent Driver/Ballast is always more than the output power. Furthermore, dim-ming drivers are less efficient at reduced power. These inefficiencies must be accounted for in the design as they will likely reduce the maximum connected load to something less than 800W. As a typical rule of thumb, provide at least 10% margin whenever the load specifics are not well known.

INSTALLATION

Illustration 1, below, shows the inverter’s main circuit board. This circuit board contains the enable switch, fuse, and wiring terminals. Approximate locations of these items are given in Illustration 1 along with details of their use. Reference this diagram for the remainder of the installation instructions.

STEP #1 INSTALLING THE EMERGENCY LIGHTING SYSTEM

• Remove front cover, circuit board tray, and any packing material inside the unit housing that may have been used for ship-ping purposes.
• Secure housing to the mounting surface through the keyhole knockouts using mounting hardware (not supplied). This hardware must be appropriate to hold the unit weight of approximately 70 lbs. with the batteries installed.
• Remove the knockouts to install input, output, and optional 0-10V dimming wiring conduit fittings.
• Extend AC supply wiring, output load wiring, and dimming control wiring into the equipment enclosure using appropriate wiring hardware and methods.
• Illustration 1 details the locations of the various wiring terminals needed for the remainder of the installation. Reference Illustration 1 for steps through 2 through 5.

STEP #2 BATTERY INSTALLATION AND CABLE CONNECTION

This product is provided with two sealed lead-acid batteries. Only the batteries supplied by the inverter manufacturer should be used. Install the batteries as shown, referring to Illustrations 2A and 2B.
With the unit secured to the mounting surface, begin installation by sliding the batteries into the enclosure. Connect the battery cables using the supplied hardware. The batteries must be connected using the provided battery connection wires. Insert the bolt into the lock-washer first, then through the retaining washer, the battery cable’s ring terminal, and finally into the threaded hole in the battery terminal (observing proper polarity by matching the cable color to the battery terminal color). Tighten to no more than 4 Ft/Lbs torque. Cover the main harness terminals with the rubber terminal cover to protect against accidental short circuits. Open the ferrite core and pass the red and black battery connector wires through and close . Connect the battery jumper cable last.
CAUTION:
DO NOT CONNECT the battery cables to Circuit Board connector X5 until the unit is ready for use. The batteries WILL BE discharged after long periods of unit inactivity while connected to the circuit board. If this occurs, the batteries will require at least 24 hours to recover before they can be used for emergency service. If left in this discharged state for extended periods, the batteries may be damaged.

STEP #3 WIRING THE EMERGENCY LIGHTING INVERTER’S PRIMARY POWER

CONNECTIONS

CAUTION

• Ensure input and output primary wiring connections are made to the proper terminals. Damage to product may occur if miswired.
• Ensure load voltage requirements match the output ratings of this product or damage to the load devices may occur.

NOTE: Make sure all connections are in accordance with the National Electrical Code, Canadian Electrical Code and any local regulations.

• Loop the load wires the once through the ferrite core
• Connect the Load Common lead to screw terminal TB-2 “OUT COM”
• Connect the Load Hot lead to screw terminal TB-2 “OUT HOT”
• Loop all input wires once through another Ferrite core
• Connect the Emergency Lighting Inverter to ground using screw terminal TB-1 “FGND”
• Connect the AC Power Source Common to screw terminal TB-1 “COM”
• Loop test switch wire once through another Ferrite core.
• Temporarily connect the test switch to X2 for installation verification purposes. The test switch will be finally installed in the enclosure lid in step 6.
• Connect the Un-switched Hot input to screw terminal TB-1 “UWSW HOT”
• Connect the Wall switch hot wire to screw terminal TB-1 “SW HOT”. This is the means of powering the load luminaires in Normal Mode when a wall switch is used to turn these luminaires on and off. If no wall switch is used, and the load luminaires are controlled by the same circuit breaker that is powering the un-switched hot. In this case TB-1 “SW HOT” must be jumped to TB-1 “UWSW HOT”.

STEP #4 WIRING THE EMERGENCY LIGHTING INVERTER’S DIMMING CONNECTIONS

(OPTIONAL)

This product features an industry-standard 0-10V dimming voltage output. Existing area dimming controls can be wired through the product’s dimming relay to allow for normal dimming by occupants of the area during Normal mode operation. The X3 connector accepts wire size # 24 AWG to # 16 AWG. Refer to Illustration 1.

STEP #5 ENABLE THE INVERTER AND APPLY AC POWER

• After installation is complete, and after the building power commissioning has been completed, apply AC mains power and then turn on SW-1 on the ELI-S-250 Circuit board.
  NOTE: The ELI-S-250 & ELI-S-185 features a “power commission lockout” that prevents the inverter from operating in the Emergency Mode unless charging power (UNSW HOT) has been applied AFTER the batteries are connected.

• At this point, the Charging Indicator Light on the test switch should illuminate indicating the battery is charging.

• A short-term discharge test may be conducted after the Emergency Lighting Inverter has been charging for 12 hours. Charge for 24 hours before conducting a long-term discharge test. Refer to OPERATION for details.

STEP #6 INSTALLATION OF ENCLOSURE LID

• Remove clip-nuts (X4) from accessory kit.
• Press on to chassis flanges, over lid mounting holes.
• Install the test switch through the hole in the lid.
• Reconnect the test switch to the PCBA.
• Place lid onto unit chassis.
• Install 8-32 screws in lid, through clip nuts(x4).

OPERATION

Normal Operation: AC power is supplied to the AC ballast/AC LED drivers within the connected luminaires through the SW HOT input. The batteries are charged from power supplied to the UNSW HOT input. Turning on SW-1 on the circuit board supplies power to the control/monitor circuit and enables the Emergency Lighting Inverter. Dimming control, if used, are passed through the unit to the connected loads.
Emergency Mode Operation and Dimming: Immediately after an AC power failure the Emergency Lighting Inverter applies back-up power to the connected loads and outputs a minimum DC voltage on the 0 – 10V dimming supply. This causes the dimmable connected loads to start out at minimum light output and consequently, minimum power draw. The ELI-S-250 & ELI-S-185 rapidly increases the 0 – 10V dimming voltage until the output power provided by the inverter reaches the products maximum emergency mode power into the connected load(s). This is referred to as Auto-Dimming. When AC power is restored, the ELI-S-250 & ELI-S-185 returns to normal charging mode. The ELI-S-250 operates the emergency lighting load for a minimum of 90 minutes. The ELI-S-185 operates the emergency lighting load for a minimum of 120 minutes.
NOTE:
Driver efficiency and power factor typically fall as dimming level decreases which must be taken into account when using the Auto-Dimming feature. This may reduce the maximum AC load connected. Contact the factory with any questions.
Self-Test: This product contains self-testing functionality. Self-test will automatically perform a 30-second test each month and a full duration test once per year (90 or 120 minutes, depending on the model). During this automatic test, the product will perform diagnostics on the battery, the battery charger, the load transfer circuitry, and the load. Any failures will be indicated by flashing of the charge indicator LED built into the illuminated test switch. This flashing will continue until either the condition has been corrected and the unit reset OR the next scheduled test has been run successfully.
Load Monitoring / Commissioning: This product complies with the latest UL standard for emergency lighting, UL 924, and includes the required load change detection circuit for use when performing the diagnostic self-test routine. When first energized, the product will automatically perform a 30-second commissioning test to detect the connected emergency lighting load level. This load level is stored in the product’s internal memory. During future tests or outages, the load level will be checked and compared against this value. If the load level deviates by more than 10%, the product will send an error code through flashing of the charge indicator LED. The inverter WILL continue to attempt to provide emergency power, regardless of error status.

MAINTENANCE & TROUBLESHOOTING

WARNING:
Always turn off SW-1(first), then turn off AC power to the equipment inside the case before servicing.
Servicing should be performed only by qualified service technicians. Use only manufacturer supplied replacement parts. Although no routine maintenance is required to keep this emergency lighting inverter functional, it should be checked periodically to ensure that it is working.

TESTING

1. Automatic self-testing performs a 30-second test once every month and a 90 minute or 120-minute test (depending on model) once per year. A failure during this test will cause the charge indicator LED to flash with a code indicating the failure type.
2. Visually inspect the charging indicator light monthly. It should be steadily illuminated. If flashing, use the table below to determine the failure mode and follow the troubleshooting steps.

If manual testing is desired, the illuminated test switch on the product cover can be used to send the product into three different test modes. These modes are detailed in the table below.

TEST SWITCH MODES

as long as the switch is depressed. During the manual test the emergency lighting load will turn off momentarily (if switched power is present). After a few seconds, the lights will turn back on in the emergency mode. Releasing the test switch will return the emergency lighting load to the normal AC mode.
Manual 30-Second Test| Press and Release the Test Switch Two Times| Manually initiates a 30-second diagnostic test. The inverter will switch to the emergency mode for 30 seconds and test all relevant functions. Once complete, the inverter returns to normal AC mode and indicate any faults, if detected.
Commissioning Test| Press and Release the Test Switch Three Times| Initiates a 30-second commissioning test. The inverter will switch to the emergency mode and store in its memory the current connected load level. If, during future self- tests, this load level deviates by more than 10%, an error will be triggered.

TROUBLESHOOTING

WIRING DIAGRAM

DIMMABLE EMERGENCY LIGHTING SYSTEM

shows an example of a branch circuit powering a number of dimmable luminaires, 4 (or more) of which are powered through the Emergency Lighting Inverter. During normal AC power mode, the power from the switched hot lighting power and 0-10V room-dimmer voltage is passed through the Inverter to the “Normal/Emergency” fixtures. The unswitched hot charges the battery. During a power failure, the Inverter powers the “Normal/Emergency” fixtures for a minimum of the products rated runtime at a power level set by the Inverter’s dimming output circuit. In any example, the dimmable “Normal/Emergency” luminaires are automatically limited to only draw a total maximum of 250 VA from the ELI-S-250 during an emergency event.

Non-DIMMABLE EMERGENCY LIGHTING SYSTEM

shows an example of an alternate emergency lighting system in which the emergency luminaires ARE NOT dimmable. In this case, the total connected Emergency lighting load MUST BE LESS THAN or EQUAL to the Inverter’s maximum output power.
