4. Installation

4.1 Where to install

The power inverter should be installed in a location that meets the following requirements:

Caution

Do not connect this inverter and another AC source (generator or utility power) to the AC wiring or AC loads at the same time. Doing so will destroy the inverter and void the warranty, regardless whether the inverter is switched on or off. If you are using more than one AC source for the AC wiring or AC loads, it is highly recommended that you install an automatic transfer switch (GP-TS), available from Go Power! Electric Inc. a) Dry - Do not allow water to drip or splash on the inverter. b) Cool - Ambient air temperature should be between 0°C and 40°C (the cooler the better). c) Ventilated - Allow at least two inches of clearance around the inverter for air flow.

Ensure the ventilation openings on the rear and bottom of the unit are not obstructed.

7

Caution!

A reverse polarity connection will permanently damage the inverter. Damage caused by reverse polarity connection is not covered by our warranty.

Warning!

You may observe a spark when you make this connection since current may flow to charge capacitors in the power inverter. Do not make this connection in the presence of flammable fumes, as explosion or fire may result.

Caution

Connecting this inverter to AC distribution wiring or

AC loads in which the neutral and ground are connected (bonded) will damage the unit and void the warranty.



d) Safe - Do not install the inverter in the same compartment as batteries or in any compartment capable of igniting flammable liquids such as gasoline. e) Inverter should be located within 10 feet of the batteries.

4.2 Hook-up and testing

To hook-up the inverter please follow these guidelines:

1. Unpack and inspect your Go Power! Inverter, check to see that the power switch is in the OFF position. We recommend using DC Install Kits whenever installing a GP

Inverter.

2. When attaching the DC inverter cables to the power input terminals on the rear panel of the power inverter. The (+) terminal is positive and (-) terminal is negative.

Connect the cables into the terminals by placing the lug connector between the washers and tighten the terminal screw or nut to clamp the wires securely. Ensure connections are tight.

3. First connect the cable from the negative terminal of the inverter to the negative terminal of the battery. Make a secure connection.

Caution! Loose connections result in excessive voltage drop and may cause overheated wires and melted insulation. Ensure connections are tight.

4. Before proceeding further, carefully check that the cable you have just connected is going from the negative terminal of inverter to the negative output terminal of the power source (battery).

5. Install the inverter fuse into the positive lead. Fuse should be located within 12” of battery. Ensure all connections are tight and secure.

6. Connect the cable from the positive terminal of inverter to the positive terminal of the battery. Make a secure connection. Check your polarity.

Caution

This inverter cannot supply power to any AC distribution wiring or AC loads in which the neutral and ground are connected (bonded). Doing so will destroy the unit and void the warranty. If you do not understand neutral to ground bonding then please have a professional install your system for you. See

“Grounding” for more information.

7. Set the power switch to the ON position. Check the meters and indicators on the front panel of the inverter. The voltage bar graph should indicate 11 to 14 volts depending on the voltage of the power source. If it is does not, check your battery bank and the connections to the inverter. The other indicators should be OFF.

8. Set the power inverter switch to the OFF position. The indicator lights may blink and the internal alarm may sound momentarily. This is normal. Plug the test load into the AC receptacle on the front panel of the inverter.

9. Set the power inverter switch to the ON position and turn the test load on; the inverter should supply power to the load. If you plan to measure the output voltage of the inverter, a true r.m.s. meter must be used for accurate readings.

8

Caution!

The negative DC input of the power inverter is connected to the chassis.

Do not install the power inverter in a positive ground DC system. A positive ground DC system has the positive terminal of the battery connected to the chassis of the vehicle or to the grounding point.

Warning!

Do not operate the power inverter without connecting it to ground.

Electrical shock hazard may result.



4.3 DC Kits

4.5 Inverter fuse

A class “T” inverter fuse should be included in all installations.

• GP 2500 - 300 amp fuse

• GP 1750 – 200 amp fuse

• GP 1000 – 110 amp fuse

4.6 Grounding

The power inverter has a lug on the rear panel: "Chassis Ground." This is to connect the chassis of the power inverter to the ground. The ground terminals in the AC outlets on the front panel of the inverter are also connected to the ground lug. To ground the GP-

2500, connect grounding wire to one of the mounting screws and sand the connection before attaching the wire.

The chassis ground lug must be connected to a grounding point, which will vary depending on where the power inverter is installed. In a vehicle, connect the chassis ground to the chassis of the vehicle. In a boat, connect to the boat's grounding systems.

In a fixed location, connect the chassis ground lug to earth.

The neutral (common) conductor of the power inverter AC output circuit is not bonded to the chassis ground. Therefore, when the chassis is connected to ground, the neutral conductor will not be grounded.

At no point should the chassis ground and the neutral conductor of the inverter be bonded. Bonding the chassis ground and the neutral conductor of the inverter or connecting the inverter to household or recreational AC distribution wiring will damage the unit and void the warranty.

5. Operation

To operate the power inverter, turn it on using the ON/OFF switch on the front panel.

The power inverter is now ready to deliver AC power to your loads. If you are operating several loads from the power inverter, turn them on separately after the inverter has been turned ON. This will ensure that the power inverter does not have to deliver the starting currents for all the loads at once.

5.1 Controls and indicators

The ON/OFF switch turns the control circuit in the power inverter ON and OFF. It does not disconnect power from the power inverter.

When the switch is in the OFF position, the power inverter draws no current from the battery. When the switch is in the ON position but with no load, the power idle current is approximately 1 A (see product specifications for exact current draw).

5.2 Optional On / Off remote

The optional remote switch can be used to turn the inverter on and off from a location up to 25 feet away. The inverter should be OFF when plugging remote in. Once the remote is installed the inverter ON/OFF switch must be in the ON position.

10



5.3 Battery voltage indicator

The battery voltage bar graph indicates the voltage at the input terminals of the power inverter. At low input current, this voltage is very close to the battery voltage. At high input current, this voltage will be lower than the battery voltage.

Ideally, the voltage should remain in the green areas of the bar graph. If the voltage goes into the red area at the top or bottom of the graph, the inverter may shut-down.

5.4 Battery current indicator

The battery current bar graph indicates the current drawn from the battery by the power inverter. It will not indicate current by other loads also connected to the battery.

For long-term operation, the current should be in the green area of the bar graph.

Short-term operation is possible with current in the yellow area. If the current rises to the red area, the inverter will shut itself down and the overload indicator will light.

5.5 Overtemp indicator

The overtemp indicator indicates that the power inverter has shut itself down because the inverter has become overheated. The power inverter may overheat because it has been operated at power levels above its rating, or because it has been installed in a location which does not allow it to dissipate heat properly. The power inverter will restart automatically once it has cooled off.

5.6 Overload indicator

The overload indicator indicates that the power inverter has shut itself down because its output circuit has been short circuited or drastically overloaded. Switch the ON/OFF switch to OFF, correct the fault condition, and then switch the ON/OFF switch back to

ON.

6. Operating limits

6.1 Power output

The inverter will operate most AC loads within its power rating. When determining whether a microwave oven can be operated by the GP-1750 Inverter, remember that the power commonly advertised for microwave ovens is the cooking power (the power delivered to the food) not the power actually consumed by the microwave oven. The microwave oven will consume 40% to 100% more than its advertised cooking power.

Check the rating sticker on the back of the oven to determine its actual power draw.

The GP-1750 inverter will operate small microwave ovens (0.2 to 0.3 cubic foot capacity) that draw about 1700 watts. It will provide 10 to 45 minutes of cooking time.

Some induction motors used in refrigerators, freezers, pumps and other motor operated equipment require very high surge currents to start. The power inverter may not be able to start some of these motors, even though their rated current draw is within the power inverter.

If the motor refuses to start, observe the battery voltage indicator while trying to start the motor. If the battery voltage indicator drops below 11 volts while the inverter is attempting to start the motor, this may be why the motor will not start. Make sure that the battery connections are good and that the battery is fully charged. If 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.

11

Note:

There are audible low voltage / over load alarms on all inverters.



6.2 Input voltage

The power inverter will operate from input voltage ranging 10 V – 15 V. If the voltage drops below 10.7 V, an audible low battery warning will sound and the voltage indicator will be in the lower red zone. The power inverter will shut down if the input voltage drops below 10 V. This protects your battery from being over discharged.

The power inverter will also shut down if the input voltage exceeds 15 V. This protects the inverter against excessive input voltage. The voltage indicator will be in the upper red zone. Although the power inverter incorporates protection against overvoltage, it may still be damaged if the input voltage is allowed to exceed 20 V.

7. Troubleshooting

7.1 Common problems

a) Buzz in audio systems

Some inexpensive stereo systems will emit a buzzing noise from their loudspeakers when operated from the power inverter. This is due to the power supply in the device does not adequately filter the modified sine wave produced by the power inverter. The only solution is to use a sound system that incorporates a higher quality power supply.

Operation of the power inverter can interfere with television reception on some channels. If this situation occurs, the following steps may help to alleviate the problem.

• Make sure that the chassis ground lug on the back of the power inverter is solidly connected to the ground system of your vehicle, boat or home. With the exception of the GP-2500 which would connect to one of the mounting screws.

• Do not operate high power loads with the power inverter while watching television.

• Make sure that the antenna feeding your television provides an adequate ("snow free") signal and that you are using good quality cable between the antenna and the television.

• Move the television as far away from the power inverter as possible.

• Keep the cables between the battery and the power inverter as short as possible and twist them together with about 2 to 3 twists per foot. This minimizes radiated interference from the cables.
