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 Figure 3-2.
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, replace the insulating barrier to its original
	position.
Communications	For multiple inverters in parallel, communications wiring is connected between
wiring	RJ45 connectors on each inverter (see Figure 3-9).
