Mounting
•
Tomountyour inverter:
1.Place the inverter on a flat surface with the
mountingbracket against the mounting surface.
2.Mount to secure surface using mounting hardware
thatis corrosion resistant (not included).
Theinverter can be mounted horizontally or vertically.

Powerwire andwiring are very importantto the performance
ofthe inverter. Because the inverter has a low voltage,
highcurrent input, low resistance wiring is essential
betweenthe battery and inverter. This is so it can deliver
themaximum amount of energy to the load.
Useonly copper wire. Aluminum wire has about one-third
moreresistance than copper wire of the same size, plus it
isdifficult to make good, low-resistance connections to
aluminumwire.
Werecommend two #4 AWG copper cables (90°C
insulationrating) as the minimum size for connections
betweenthe battery and inverter.
Keepthe cable length as short as possible, no more
thanfour feet (one and one-half meters). This will keep
thevoltage drop to a minimum.
Ifthe cable has too much voltage drop, the inverter
mayshut down when drawing higher currents because
voltageat the inverter may drop below 10 volts. If you
mustuse longer cables, choose thicker cables, such as
#2AWG, and trimthe ends of the cableto fit the terminals.
Toconnectthe cables betweenthe inverter
andthe battery:
1.Turn the On/OffSwitch on the inverter to the off
position.If the power source is a DC power supply,
switchit off as well.
2.On the end of the cable that connects to the inverter,
stripback the insulation about one-half inch (one and
