Mounting
•
To mount your inverter:
1.Place the inverter on a flat surface with the mounting bracket against the mounting surface.
2.Mount to secure surface using mounting hardware that is corrosion resistant (not included).
On/Off Switch to Off
The inverter can be mounted horizontally or vertically.

Power wire and wiring are very importantto 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.
Use only copper wire. Aluminum wire has about
We recommend two #4 AWG copper cables (90°C
insulation rating) as the minimum size for connections

between the battery and inverter.
Keep the cable length as short as possible, no more than four feet (one and
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 connectthe cables betweenthe inverter and the battery:
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.
