Installation
Connect the Chassis Ground
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.
Connect The Battery Cables
To operate safely and effectively, the PROwatt SW Inverter needs
proper DC cables and DC-rated fuse(s). Because the PROwatt SW
Inverter has low-voltage and 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.
ELECTRICAL SHOCK HAZARD
Never operate the PROwatt SW Inverter without connecting it to
the ground.
Failure to follow these instructions will result in death or
serious injury.
Recreational
Vehicle
Connect the CHASSIS GND screw to the
vehicle’s chassis using a minimum 8 AWG
copper wire
a
(preferably with green/yellow
insulation).
Fixed Location
Connect the CHASSIS GND screw to your
system’s DC grounding point using a minimum
6 AWG wire
a
. 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.
a.Xantrex recommends that the grounding conductor (grounding wire) should be the same wire
size as the DC cables.
IMPORTANT:
Use of a qualified installer strongly recommended.
