Be sure to have on hand:
Installation

between 11 and 15 volts DC and
be able to supply enough current to
run the test load. As a rough guide,
divide the wattage of the test load by

10 to get the current (in amperes)
the power source must deliver.
Cables to connect the power source to the inverter.
Cables are supplied with the unit that are two feet
long overall from the tip of the clamp shown to the
stripped and tinned end for insertion in the Input
End of the unit.
If user supplied cables are to be used, they must be
as short and thick as possible in order to reduce the
voltage drop between the power source and the inverter
when it is drawing current from the power source.
If the cable suffers an excessive voltage drop, the inverter
may shut down when drawing higher currents because
the voltage at the inverter dropped below 10 volts.
A test load that can be plugged into the AC receptacle on
the inverter for short term testing at a low power level.
The following cables are recommended for testing low
power level test loads only.
