• 7 mm socket and small ratchet, or 7 mm open wrench.
To remove the inverter from the wiring box:

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.
