Connection
For the power inverter to work properly, your power source must provide 12 volts DC,
and the power source must provide enough current (i.e., 46 amps to operate the load
of 560 Watts or under).
Caution: This inverter must only be connected to batteries with a nominal out-
put voltage of 12 volts. Lower voltage will not operate the inverter properly, and
more voltage could damage the inverter or the device being powered. If more
than one 12 volt battery is to be used, the batteries must be connected in a
parallel circuit; batteries connected in a series circuit will produce too much
voltage.
1. Place the Power Inverter on a flat surface. Make sure it has adequate ventila-
tion and is not in direct sunlight. Fasten the inverter securely to the surface,
using screws or some other means. If holes are to be drilled, follow safe, proper
installation techniques.
2. Connect the Battery Cable (not included; #2 AWG or larger cables recommended)
lugs to the (Positive) red and (Negative) black terminals on the back of the
Inverter, see
BACK
above. Connect the Ground Cable (not included; #4 AWG or
larger cable recommended) lug to the Ground terminal, see
BACK
above. Se-
curely tighten.
3. The Power Inverter can be used either while the engine is running or off. Con-
nect the Battery Cables (not included) to the Negative (black) and Positive (red)
terminals of the battery.
4. Connect the Ground Cable to the appropriate location below:
a. If this unit is mounted within a vehicle with a grounded metal chassis,
attach the Ground Cable to a nearby location on the chassis.
b. If this unit is mounted in a boat or vehicle with an ungrounded chassis,
attach the Ground Cable to the vehicle’s grounding system.
c. ONLY if this unit is being used outside a vehicle,
attach the Ground Cable to the Negative Terminal of the Inverter.
