This section provides you with basic information

 

about the inverter and how to check its perfor-

 

mance before installation. Be sure to have the fol-

 

lowing on hand:

 

A 12 volt DC power source (such as a vehicle battery)

 

A set of cables to connect the power source to the inverter

 

A test load that can be plugged into the AC receptacle

 

on the inverter

 

Power Source

 

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 10 to get the current (in

 

amperes) the power source must deliver.

 

Cables (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 may shut down when drawing higher cur-

 

rents because the voltage at the inverter dropped

 

below 10 volts.

 

#4 AWG stranded copper cable is recommended. It

 

should be no longer than 1.5 meters (4 ft.). For

 

short term testing at a low power level, the

 

following is recommended:

Minimum Cable Size

# 16 AWG copper

250 w

# 12 AWG copper

500 w

# 8 AWG copper

The end of the cable that connects to the invert- er must have its insulation stripped off for about 1/2 inch (1.25cm) back from the end, exposing the bare copper.

The other end of the cable, which connects to the power 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.

Connection

1.Turn the ON/OFF switch on the inverter to the OFF position.

If the power source is a DC power supply, switch it off as well.
