Power wire and wiring are very important to the
performance of the inverter. Because the inverter has a
low voltage, high current input, low resistance wiring is
essential between the battery and inverter. This is so it
can deliver the maximum amount of energy to the load.
Keep the cable length as short as possible, no more than
four feet (one and a half meters). This will keep the voltage
drop to a minimum.
If the cable has too much voltage drop, the inverter may
shut down when drawing higher currents because voltage
at the inverter may drop below 10 volts. If you must use
longer cables, choose thicker cables, such as #2 AWG,
and trim the ends of the cable to fit the terminals.
To connect the cables between the
inverter and the battery:
1.
Press the
Power Button
on the inverter to the
off
position. If the power source is a DC power supply,
switch it
off
as well.
2.
Connect cable to the
Power Input Terminals
on input
end of the inverter. The red terminal is positive (+) and
the black terminal is negative (-). Insert the bare ends
of the cables into the terminals and tighten the screws
to clamp the wires securely.
It is a good idea to check and tighten these screws
from time to time. They can become loose by vibrations
or thermal cycling.
3.
Connect cables to the power source:
a.
Connect the cable from the
Negative (Black)
Terminal
of inverter to the
Negative Terminal
of the power source. Make a secure connection.
