Accessing the Wiring Terminals
You must remove the GT Inverter wiring box cover to access the terminal blocks,
ground bar and communications ports (for inverters in parallel).
To remove the wiring box cover:
1. Using a Phillips screwdriver, remove the two screws on the bottom side of the
wiring box and set in a safe place (see Figure 3-1 for location of screws).
2. Lift the cover off the wiring box.
When replacing the wiring box cover, be careful not to pinch any wires in the
wiring box.
AC and DC connections are made at the wiring terminals shown in Figure3-2.
Insulating barrier The clear plastic insulating barrier inside the wiring box is a permanent
component. It is intended to separate the high-voltage AC and DC wiring from
any communications cabling and to prevent wiring from coming into contact with
the wiring box cover.
When wiring the unit, it is necessary to pull the cover back to access the wiring
terminals. After completing the wiring, repla ce t he insul ating ba rrie r to i ts orig inal
