Ground Wiring
The PROwatt 1500 has a screw terminal on the rear panel labeled Chassis Ground. This is to connect the chassis
of the PROwatt 1500 to ground. The ground terminal in the AC outlet on the front panel of the PROwatt 1500 is
connected to the chassis.
The chassis ground terminal must be connected to a grounding point, which will vary depending on where the
PROwatt 1500 is installed. In a vehicle, connect the chassis ground to the chassis of the vehicle. In a boat, con-
nect to the boat's grounding system. In a fixed location, connect the chassis ground lug to earth ground by con-
necting to a ground rod (a metal rod pounded into the earth) or other proper service entrance ground. Use a #8
AWG or larger copper wire (preferably with green/yellow insulation) to connect the chassis ground terminal to
the grounding point. In some installations a larger wire size may be required. Refer to the local/national codes
applicable for your type of installation.
The neutral (common) conductor of the PROwatt 1500 AC output circuit is connected to chassis ground. There-
fore, when the chassis is connected to ground, the neutral conductor will also be grounded. This conforms to Na-
tional Electrical Code requirements that separately derived AC sources (such as inverters and generators) have
their neutral conductors tied to ground in the same way that the neutral conductor from the utility line is tied to
ground at the AC breaker panel.
WARNING! Do not operate the PROwatt 1500 without connecting it to ground. Electrical shock hazard
may result.
