Connecting DC Cables

Grounding Locations

The chassis ground terminal must be connected to a grounding point, which varies depending on where you install the PROwatt 600. Follow the guidelines that correspond to your type of installation.

Vehicle Connect the CHASSIS GND screw to the vehicle’s chassis using 8 AWG copper wire (preferably with green/ yellow insulation).

Marine Connect the CHASSIS GND screw to the boat’s DC grounding bus or the engine’s negative bus using 6 AWG copper wire that has insulation rated at 90º C.

Fixed Location (residential, for example). Connect the CHASSIS GND screw to your system’s DC grounding point using 6 AWG wire. The system’s grounding point will usually be the AC service entrance grounding point or a separate ground rod. For a solar PV (photovoltaic) installation, this is usually the same ground rod used to ground the PV array.

Connecting DC Cables

Proper cables and wiring are essential to effective operation of the PROwatt 600. Because the PROwatt 600 has a low voltage, high current input, low-resistance wiring between the battery and the inverter is essential to deliver the maximum amount of usable energy to your load.

Cabling Guidelines

Deviating from these guidelines will cause excessive voltage drop or melting of the cable and/or connectors. The inverter may also shut down or fail to operate some loads.

•Make sure each cable between the inverter and the battery is no longer than 4 feet (1.2 m).

•Use 4 AWG copper (90º C insulation rating).
