Loose connections result in excessive voltage drop and
may cause overheated wires and melted insulation.
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 the warranty.
4. Before proceeding further, carefully check to ensure that the cable connects
from the negative DC input of the inverter to the negative terminal of the
battery.
You may observe a spark when you make the positive
connection since current may flow to charge capacitors
in the inverter. Do not make this connection in the
presence of flammable fumes, as explosion or fire may
result.
5.
Install the recommended inverter fuse in the positive lead; see section 4.3
Cables. The fuse should be located as close to the battery as possible.
Ensure all connections are tight and secure.
6.
Securely connect the positive cable (red) to the positive terminal of the
battery.
7.
Set the power switch to the ON position. Check the indicator LED on the
front panel of the inverter to ensure that it is green.
8.
Set the 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.
9. Set the inverter switch to the ON position and turn on the test load; the
inverter should supply power to the load. If you plan to measure the output
voltage of the inverter, a true RMS meter must be used for accurate
readings.
