Installation

Guidelines
Follow all instructions from this guide and instructions including safety guidelines from the battery manufacturer. Installing battery cables require some electrical knowledge and local electrical codes.

WARNING
IMPROPER INSTALLATION BY AN UNQUALIFIED INSTALLER
If you do not have some electrical knowledge and knowledge of local electrical codes or are not comfortable installing cables yourself, use a qualified installer including a licensed technician and electrician.
Qualified installers have knowledge and experience in installing electrical equipment, knowledge of the applicable installation codes, and awareness of the hazards involved in performing electrical work and how to reduce those hazards.
Failure to follow these instructions can result in death or serious injury.

Tools and Materials

• Adjustable wrench for fastening DC terminal bolts,
• Two battery cables (copper, appropriately sized according to application) with connectors already crimped by the company or store where you purchased the cables,
• Ground cable (copper, appropriately sized) for attaching to the ground chassis,
• DC-rated fuses (and fuse holders),
• Screwdriver (flathead and Philips), power screwdriver, or power drill for use in mounting the inverter,
• Mounting screws (4) size #10.

Basic Installation Steps

1. Determine battery capacity.
2. Determine a charging system.
3. Choose a location.
4. Mount the inverter.
5. Connect the chassis ground.
6. Connect the battery cables.

Determine Battery Capacity
Battery type and battery size strongly affect the performance of the PurePower 1800 inverter. Therefore, you need to identify the type of loads your inverter will be powering and how much you will be using them between charges. Once you know how much power you will be using, you can determine how much battery capacity you need. It is recommended that you purchase as much battery capacity as possible.

CAUTION
RISK OF INVERTER DAMAGE
Connect only to a battery that has a nominal output of 12 volts.
Do not connect to 6-volt or 24-volt battery systems.
Failure to follow these instructions can damage the unit and/or damage other equipment.

Determine A Charging System
The charging system must be appropriate for your particular installation. A well-designed charging system will ensure that power is available when you need it and that your batteries remain in top condition. Inadequate charging will degrade system performance and the wrong type of charger will reduce battery life.
Contact Customer Service for battery recommendations.

Choose A Location
Install the PurePower 1800 inverter in a location that meets the following requirements:

º C)—the cooler the better within this range.
Ventilated| Allow at least 2 inches (5 cm) of clearance around the inverter for air flow. Ensure that ventilation openings on the
DC end and the bottom of the unit are not obstructed.
Safe| Do not install the inverter in the same compartment as batteries or in any compartment capable of storing flammable liquids like gasoline.
Close to battery| Do not use excessive DC cable lengths: they increase wire resistance and reduce input power.
Protected from battery gases| Do not mount the inverter where it will be exposed to gases produced by the batteries. These gases are very corrosive and
prolonged exposure will damage the inverter.

NOTES:
When planning to install the PurePower 1800 inverter, be sure that you consider the location and orientation carefully.
The inverter may be used in marine applications beneath the weather deck that are always dry and protected from prolonged and sustained exposure to moisture and water. Even with the installation of additional drip protection such as drip shields1 , this will not prevent the entry of dripping water when the inverter is installed in outside areas of boats such as on the promenade or on the main and weather decks.

CAUTION
ELECTRICAL SHOCK HAZARD
Do not install in an open cockpit or on the weather deck of a marine vessel.
Failure to follow these instructions can result in minor or moderate injury.

Mount The Inverter

1. Select an appropriate mounting location and orientation. The unit can be oriented in any way, such as:
   • Horizontally on a vertical surface or• On or under a horizontal surface.

2. Hold the inverter against the mounting surface and mark the positions using the mounting flanges as guide.

3. Pilot-drill the four mounting holes.

4.  Fasten the inverter to the mounting surface using corrosion-resistant hardware sized #10.

Connect the Chassis Ground

DANGER
ELECTRICAL SHOCK HAZARD
Never operate the PurePower 1800 inverter without connecting it to the ground.
Failure to follow these instructions will result in death or serious injury.

The PurePower 1800 inverter has a screw terminal labeled CHASSIS GND on the outside of the rear panel as shown in Figure 3, “PurePower 1800 inverter Back Panel” on page 5.
Follow the guidelines below to connect the inverter’s chassis to the ground.
Grounding Locations
The chassis ground terminal must be connected to a grounding point. The grounding point varies depending on where you install the PurePower 1800 inverter. Follow the guidelines that correspond to your type of installation.

Recreational Vehicle| Connect the CHASSIS GND screw to the vehicle’s chassis using a minimum 8 AWG copper wirea
(preferably with green/yellow insulation).
---|---
Fixed Location| Connect the CHASSIS GND screw to your system’s DC grounding point using a minimum 6 AWG wire.
The system’s grounding point is usually the AC service entrance grounding point or a separate ground rod. For a solar PV (photovoltaic) installation, this is usually the same rod used to ground the PV array.

a.It is recommended that the grounding conductor (grounding wire) should be the same wire size as the DC cables.

Connect The Battery Cables
To operate safely and effectively, the PurePower 1800 inverter needs proper DC cables and DC-rated fuse(s). Because the PurePower 1800 inverter has low- voltage and high-current input, low-resistance wiring between the battery and the inverter is essential to deliver the maximum amount of usable energy to your load.
IMPORTANT: Use of a qualified installer strongly recommended.

Cabling Guidelines
Follow these guidelines and refer to Table 1.

• Use 1/0 AWG copper (75 ºC insulation rating) as the smallest battery cable size. It is the lightest gauge required by code and it will minimize the voltage drop between the battery and the inverter. If the cables cause an excessive voltage drop, the inverter may shut down when drawing higher currents because the voltage at the inverter input drops below 10.5 volts.
• Have all wires and cables terminated with correct and appropriately-sized connectors and have the connectors crimped at the place of purchase.
• Do not use aluminum wire. It has about 1.5 more resistance  than copper cable of the same size, and it is difficult to make good, reliable connections.

Table 1 : Voltage Drop Per Foot of DC Cable

| Inverter Output (W)| 1000| 1500
---|---|---|---
Current (A)| 100| 150
Wire Size (AWG)| Resistance (ohms/ft) @ 25 °C| Voltage Drop per Foot
0| 0.000100| 0.0100| 0.0150
2/0| 0.000079| 0.0079| 0.0119
3/0| 0.000063| 0.0063| 0.0095
4/0| 0.000050| 0.0050| 0.0075

Note: It is recommended that a size 0 cable with a maximum cable length of 6 feet (1.8 m) be used.

Fuse/Circuit Breaker Sizing Guidelines
Because batteries can produce thousands of amps, you are required to install DC-rated fuses (or circuit breakers) that can safely withstand the short- circuit current batteries can produce.

To select the correct fuse type and size:

1. Determine the total cold cranking amp rating for your battery(s).
   Note: The cold cranking amp rating of each battery is displayed on the battery case. If it is not, contact the battery manufacturer to find out.
   For example:
   • If you are using one battery to power your inverter and its rating is 500, the total cold cranking amp rating is 500.
   • If you are powering your inverter with two batteries in parallel, and each has a rating of 500, the total cold cranking amp rating is 1000.

2. Once you have determined the total cold cranking amp rating of your batteries, identify the corresponding Ampere Interrupting Capacity (AIC) of the fuse or breaker required for your system by referring to Table 2.

Note: The AIC is the amount of battery short-circuit amperage that the fuse can safely withstand.

• If the Total Cold Cranking Amps indicate that the AIC is 2,700 amps or less, see Table 3 for the correct ANL fuse.
• If the Total Cold Cranking Amps indicate that the AIC is up to 200,000 amps or if you require a “code fuse”, see Table 3 for the correct Class T fuse.

Table 2 Cold Cranking Amps / AIC

Table 3 Fuse Ratings

| ANL Fuse| Class T
---|---|---
PurePower 1800| 250 A| 250 A

Cabling Procedure
Consult the following configurations and determine a match specific to your installation and follow the installation procedure “To connect the battery cables:” that comes next.

To connect the battery cables:

1. Make sure the inverter is off and assemble the terminated cables (cables with connectors) that you bought.

2. Line up the connectors that will join the cables to the battery, battery selector switch, and fuse (or circuit breaker).
   DANGER
   ELECTRICAL SHOCK AND FIRE HAZARD
   Install a DC-rated fuse (and fuse holder) on the positive battery terminal. Note that the PurePower 1800 inverter does not come with a DC-rated fuse (or circuit breaker) to safely withstand the short-circuit current batteries can produce.
   Failure to follow these instructions will result in death or serious injury.

3. Install a DC-rated fuse on the positive battery terminal.
   Alternatively, install a DC-rated circuit breaker that connects to the positive battery terminal.
   The fuse (or circuit breaker must have an Ampere Interrupting Capacity (AIC) that exceeds the short-circuit current available from the battery. For guidance, see “Cold Cranking Amps / AIC” on page 11.

4. When configuring for heavy loads (see Figure 5), install a battery selector switch and connect it to the DC-rated fuse (or circuit breaker).

5. On the inverter side, attach the connectors of the positive and negative cables into the cabling terminals of the inverter.
   Note: Make a secure connection. Loose connectors cause excessive voltage drop and may cause overheated wires and melted insulation.
   Note: The red terminal is positive (+) and the black terminal is negative (–). Power connections to the PurePower 1800 inverter must be positive to positive and negative to negative.
   DAMAGE DUE TO REVERSE POLARITY
   Do not connect positive cables to negative terminals (and viceversa) as this will blow  a fuse in the inverter and may permanently damage the unit. Damage caused by a reverse polarity connection is not covered by your warranty.
   Failure to follow these instructions can damage the unit and/or damage other equipment.

6. Attach the connector on the positive cable to the DC-rated fuse (or circuit breaker) which is connected to the positive terminal of the battery.
   When configuring for heavy loads (see Figure 5), attach the connector on the positive cable to the battery selector switch that is already connected to the DC-rated fuse (or circuit breaker).
   Note: Make a secure connection. Loose connectors cause  excessive voltage drop and may cause overheated wires and melted insulation.
   DANGER
   EXPLOSION AND FIRE HAZARD
   Do not complete the next step if flammable fumes are present.
   Thoroughly ventilate the battery compartment before making this connection.
   Failure to follow these instructions will result in death or serious injury.

7. Attach the connector on the negative cable to the negative battery terminal.
   Note: This is the last cable connection. You may observe a spark when making this last connection.
   Note: Make a secure connection. Loose connectors cause excessive voltage drop and may cause overheated wires and melted insulation.

8. If you have installed a battery selector switch, use it to select one of the batteries or battery banks.

9. Turn on the inverter.

10. Check the front panel of the inverter. The digital display should show 12–13 volts, depending on the voltage of the battery. If it does not, check your battery and the connection to the inverter.
    The other indicators should be off.

Operation

Turning the Inverter On and Off
The power switch on the inverter’s front panel turns the control circuit in the PurePower 1800 inverter on and off.
To toggle the inverter on and off from its front panel:

1. Press the inverter’s power switch button (for half a second) to turn On the inverter (from Off).
2. Press the inverter’s power switch button (for one second) to turn Off the inverter (from On).

Note: When the inverter’s power switch button is Off, the inverter draws no current from the battery.
IMPORTANT: The unit’s power switch when turned off does not disconnect power from the PurePower 1800 inverter.

Operating Several Loads at Once
If you are going to operate several loads from the PurePower 1800 inverter, turn them on separately after you have turned the inverter on. This will ensure that the inverter does not have to deliver the starting current for all the loads at once.
Turning the Inverter Off Between Charges
If you are not planning to recharge your battery for a few days, switch the inverter off.

GFCI-Protected AC Outlets
The AC outlets are Ground Fault Circuit Interrupter (GFCI) outlets.
This protects you against hazardous electrical shocks that could be caused by dampness, faulty mechanism in the appliance, worn insulation, etc.
IMPORTANT: Test the GFCI periodically to make sure it is operating correctly.
To test (or reset) the GFCI protection:

1. Press the unit’s power switch to turn the inverter On.
2. Plug a test lamp into the AC outlet.
3. Push the TEST button.

Note: The RESET button should pop out and the power should turn Off (the lamp should go out). If the lamp remains lit, or if the RESET button does not pop out, the GFCI may not be functioning.
If the GFCI trips by itself at any time, reset it and perform the preceding test.

Reading the Front Panel Indicators
Indicator LEDs

• If the Green LED is On, it indicates that the unit is On. Under normal operating conditions, the AC outlets and USB port have power. However, even under an error condition such as a shutdown, the Green LED may still remain On.
• If the Red LED is on, it indicates an error or alarm condition and an error code is displayed on the digital display underneath the LED.

Digital Display

• Under normal operating conditions, the digital display shows the input voltage (in volts) and the output power (in kilowatts).
• Under error or alarm conditions, the digital display shows an error code and the Red LED turns on.

Description of LED and Digital Display Codes

Note: The audio alarm will sound for five minutes. After five minutes, the unit will turn off.

Restarting After an AC Output Shutdown

1. Press and hold the unit’s power switch to turn it Off.
2. Remove all AC loads or let the unit cool down for 15 minutes.
3. Press and hold the unit’s power switch to turn it On.

Operating Limits
Power Output
The PurePower 1800 inverter will deliver the following power continuously, depending on input voltage and ambient temperature. The inverter will deliver more than 10% of its continuous power rating for approximately five minutes. The inverter must cool down for 15 minutes before it can resume operation above its continuous power rating.

| Powera| Output Currentb| Input Voltage| Temperature
---|---|---|---|---
PurePower 1800| 1800 W| 15 A| 13 Vdc| Ambient 25 °C (77 °F)

a.Applies to resistive loads such as incandescent lights.
b.Applies to reactive loads such as motors.

Input Voltage
The input voltage limits are shown in the following table.

sounds.
Low Voltage Shutdown| Voltage is 10.5 V or less.| The unit shuts down to protect the battery from being over-discharged.
High Voltage Shutdown| Voltage is 15.5 V or more.| The unit shuts down to protect itself from excessive input voltage.
Note: Although the PurePower 1800 inverter incorporates over-voltage protection, it can still be damaged if input voltage exceeds 16 V.
Unit restarts after low voltage shutdown| 11.5 V| The unit will not restart unless the battery voltage is acceptable for running the load.

Inverter Loads
The PurePower 1800 inverter will operate many AC loads within its  power rating. However, some appliances and equipment may bedifficult to operate. Please see “Exceptional Loads” below carefully.
USB Loads
A lot of USB-powered devices such as portable music (MP3) players, mobile phones, and video game players can be charged and powered safely via the standard USB port. However, some devices such as portable GPS receivers and certain cameras may not work
and even cause damage even if you use the USB cable that came with the product. Be sure that the device only accepts 5 volts and can be charged or powered using other sources of power. See the device’s owner’s guide under specifications for information.
Exceptional Loads
Some household appliances such as freezers, pumps, and other motor-operated equipment need high surge currents to start. The PurePower 1800 inverter may not be able to start some of these motors even though their rated current draw is within the inverter’s
limits.
If a motor refuses to start, observe the VOLTS indicator while you are trying to start the motor. If the indicator drops below 11 volts while the PurePower 1800 inverter is trying to start the motor, this may explain why the motor won’t start. Make sure the length and wire gauge of the battery cables are appropriate. See Table 1. Check that the battery connections are good and that the battery is fully charged. If the cables are sized correctly, the connections are good, and the battery is charged, but the voltage still drops below 11 volts, you may need to use a larger battery.
Battery Charging Frequency
When possible, recharge your batteries when they are about 50% discharged or earlier. This gives them a much longer life cycle than recharging when they are almost completely discharged.
Maintenance
Routine maintenance is required to keep your PurePower 1800 inverter operating properly. Periodically you should:

• Clean the exterior of the unit with a damp cloth to prevent the accumulation of dust and dirt.
• Tighten the screws on the DC input terminals.
