4.2 Hook-up and testing
1. Unpack and inspect your Go Power! Inverter, check to see that the power switch
is in the OFF position.
2. Connect the negative cable (black) 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.
3. Before proceeding further, carefully check that the cable you have just connected,
connects from the negative terminal of inverter to the negative output terminal of
the power source.
4. Install the recommended inverter fuse in positive lead. Fuse should be located
within 12” of battery. Ensure all connections are tight and secure. (See 4.3)
5. Connect the positive cable (red) to the positive terminal of the battery. Make a
secure connection.
6. Set the power switch to the ON position. Check indicator on the front panel of
the inverter to ensure that it is red.
7. Set the power inverter switch to the OFF position. The indicator light 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.
8. 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.
4.3 Cables
Please use a 40 amp fuse (not included) with the supplied #10 Cable. Install the inverter
fuse into the positive lead. Fuse should be located within 12” of battery. Ensure all
connections are tight and secure.
4.4 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 of the inverter are also connected to the ground lug.
If available, the chassis ground lug should be connected to a ground 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.
Warning!
Do not operate the
power inverter
without connecting it
to ground. Electrical
shock hazard may
result.
Caution!
A reverse polarity
connection will blow a
fuse in the inverter and
may 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 the positive
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.
