2. Insert DC inverter cables (not included) to the power input terminals on the

rear panel of the power inverter. The red terminal is positive (+) and black

terminal is negative (-). Connect the cables into the terminals and tighten

the terminal screw to clamp the wires securely.

3. Connect the cable from the negative terminal of the inverter to the

negative terminal of the battery. Make a secure connection.

Loose connections result in excessive voltage drop and may

cause overheated wires and melted insulation.

4. Before proceeding further, carefully check that the cable you have just

connected connects from the negative terminal of inverter to the negative

terminal of the power source (battery).

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.

5. Install inverter fuse (not included) in positive lead. Fuse should be located

within 12” of battery. Ensure all connections are tight and secure. (See

Section 4.3)

6. Connect the cable from the positive terminal of inverter to the positive

terminal of the battery. Make a secure connection.

7. Set the power switch to the ON position. Check the indicators on the front

panel of the inverter. The Input Level LED should be green or yellow,

depending on the voltage of the power source. If it is not, check your

battery bank and the connections to the inverter.

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.

Leave the test load switch OFF.

(For the Hard Wire option, please see Section 4.3).

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 rms meter must be used for accurate

readings.

The GFCI outlet of the GP-SW3000 is rated for 20 amps or

2200 W. For loads above 20 A or 2200 W please use the Hard

Wire option.
