Installation
Connect the Chassis Ground
WARNING: Risk of electrical shock.
Never operate the PROwatt SW Inverter without connecting it to the ground. Electrical shock hazard could result.
Fixed Location
Connect the CHASSIS GND screw to your system’s DC grounding point using a minimum
6 AWG wirea. The system’s grounding point is usually the AC service entrance grounding point or a separate ground rod. For a solar PV (photovoltaic) installation, this is usually the same rod used to ground the PV array.
The PROwatt SW Inverter has a screw terminal labeled CHASSIS GND on the outside of the rear panel as shown in Figure 3, “PROwatt SW Inverter Back Panel (PROwatt SW 600 shown)” on page 5.
Follow the guidelines below to connect the inverter’s chassis to the ground.
Grounding Locations
The chassis ground terminal must be connected to a grounding point. The grounding point varies depending on where you install the PROwatt SW Inverter. Follow the guidelines that correspond to your type of installation.
a.Xantrex recommends that the grounding conductor (grounding wire) should be the same wire size as the DC cables.
Connect The Battery Cables
Important: Use of a qualified installer strongly recommended.
To operate safely and effectively, the PROwatt SW Inverter needs proper DC cables and
Recreational Vehicle
Connect the CHASSIS GND screw to the vehicle’s chassis using a minimum 8 AWG
copper wirea (preferably with green/yellow insulation).
