Recommended tools:

•7 mm socket and small ratchet, or 7 mm open wrench.

WARNING: Shock hazard

The inverter should only be removed from the wiring box when a replacement inverter is immediately available. When replacing an inverter, ensure the AC/DC Disconnect switch is locked (or otherwise secured) in the OFF position. Do not leave the top of the wiring box exposed for extended periods of time.

WARNING: Shock hazard

Before replacing the inverter, turn OFF the breaker switches in the main utility service panel and the AC/DC Disconnect switch on the GT Inverter.

To remove the inverter from the wiring box:

1.Turn OFF the breaker switches in the main utility service panel and the AC/DC Disconnect switch on the GT Inverter. If possible, cover the PV arrays with an opaque material.

2.Remove the covers from the wiring box and inverter front (described on page 2–23 and page 3–2).

3.Using an insulated screwdriver, disconnect the PV NEGATIVE (–) wire from the terminal block inside the inverter. Cap the wire immediately with a wire nut.

4.Disconnect the remaining AC, DC and communications wires between the inverter and the wiring box, inside the inverter. Cap all disconnected AC and DC wires with wire nuts.

5.Inside the inverter, remove the four nuts attaching the wiring box to the inverter.

6.Lift the inverter off the mounting bracket, leaving the wiring box in place.
