4.5 Grounding
The negative DC input of the power inverter is connected to the
chassis. Do not install the power inverter in a positive ground DC
system. A positive ground DC system has the positive terminal of the
battery connected to the chassis of the vehicle or to the grounding
point.
Do not operate the power inverter without connecting it to ground.
Electrical shock hazard may result.
The power inverter has a lug on the rear panel [chassis ground]. This is to connect the
chassis of the power inverter to ground. The ground terminals in the AC outlets on the
front panel of the inverter are also connected to the ground lug.
The chassis ground lug must be connected to a grounding point, which will vary
depending on where the power inverter is installed. In a vehicle, connect the chassis
ground to the chassis of the vehicle. In a boat, connect to the boat's grounding systems. In
a fixed location, connect the chassis ground lug to earth.
The neutral (common) conductor of the inverter AC output circuit is connected (bonded) to
the chassis ground inside the inverter. Therefore, when the chassis is connected to
ground, the neutral conductor will also be grounded. This conforms to national electrical
code requirements that states that separately derived AC sources (such as inverters and
generators) have their neutral tied to ground in the same way that the neutral conductor
from the utility line is tied to ground at the AC breaker panel.
If the inverter is supplying power to equipment or a panel where the
neutral and ground are connected (bonded), a ground loop will occur. If
a ground loop occurs, the GFCI outlet will trip and output power from the
inverter will be cut off. If your GFCI repeatedly needs to be reset, this
would indicate a ground loop somewhere in your system. In this case,
please have a qualified person inspect your electrical system or
equipment.
