Installation
3–12
The neutral (common) conductor of the inverter AC output circuit is
connected to the chassis ground. Therefore, when the chassis is connected
to ground, the neutral conductor is also grounded. This conforms to
National Electrical Code requirements stating that separately derived AC
sources (such as inverters and generators) must have their neutral
conductors tied to the ground in the same way that the neutral conductor
from the utility line is tied to the ground at the AC breaker panel.
Grounding Locations
The chassis ground terminal must be connected to a grounding point. The
grounding point varies depending on where you install the PROwatt
3000. Follow the guidelines that correspond to your type of installation:
Recreational Vehicle Connect the chassis ground lug to the vehicle’s
chassis using 8 AWG copper wire (preferably with green/yellow
insulation) or larger.
Marine Connect the chassis ground lug to the boat’s DC grounding bus
or the engine’s negative bus using 2 AWG copper wire that is bare or has
insulation rated at 90º C.
