Wiring the Inverter
3–10 975-0320-01-01
Connecting the AC Wiring
The GT Inverter can be connected to a single bi-directional meter, or to dual
meters, where one meter indicates power used and the second meter indicates
power sold (power supplied back to the utility). Consult the local utility to
determine the proper components to install, and obtain any permits required prior
to installation.
Ensure all connections are correctly wired and properly torqued to a maximum
16 in-lb (1.8 Nm).
The AC wiring procedure is illustrated in Figure 3-9.
WARNING: Shock hazard
Before wiring the GT Inverter, ensure the main breaker in the primary utility breaker box
is switched OFF. Switch this breaker ON only after all wiring is completed as instructed in
the procedures.
Important: The neutral conductor must be attached to the inverter in all cases. The
neutral conductor is used for phase-to-neutral voltage sensing only and is not a current
carrying conductor. This conductor is not bonded to ground in the inverter.
