Quick Evaluation Before Installation

This section provides you with basic information about the
inverter and how to check its performance before installation.
Be sure to have on hand:
Installation
1. A 12 volt DC power source (such as a vehicle battery).
Secondary Icons
Connect Power Source
2. Cables to connect the power source to the inverter
(not included).
The cables 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
ain Icons
may shut down when drawing higher currents because
the voltage at the inverter dropped below 10 volts.
#4 AWG stranded copper cable is recommended.
It should be no longer than four feet (one and one-half
meters).
Intro Operation Customer
The other end of the cable, which connects to the power Assistance
source, must be terminated with a lug or other connector
that provides a secure, low resistance connection.
For example, if the power source is a battery, the cable

must be terminated with a battery terminal that clamps
to the post on the battery.

The power source must provide
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
