Switching off AC and DC supplies
1. Turn the AC circuit breaker to off.
2. Set the DC circuit breaker on the inverter to position 0
(Figure 31).
Disconnecting DC connections from the inverter
Disconnect the Amphenol Helios H4 to Multi-Contact MC4 connectors of the
DC cables according to the manufacturer's instructions. A special tool is required
for this.
Warning
DC cables are under current if light falls on the modules.
Disconnecting the AC plug from the inverter
For the Turbo 1P inverter:
1. Remove the AC plug from the socket on the inverter as described in chapter 13.1.
2. Check that all pins of the AC plug are free of voltage. Use a suitable voltmeter for
this (do not use a simple neon phase checker).
For the Turbo 3P1 / 3P2 inverter:
1. Disconnect the AC plug from the inverter: gently press in the ratchet near the
front of the AC plug with a suitable object to unlock it, and remove the plug.
2. Check that all pins of the AC plug are free of voltage. Use a suitable voltmeter for
this (do not use a simple neon phase checker).
Opening the AC plug (only if required)
For the Turbo 1P inverter:
Open the AC plug as described in the Appendix under Mounting > AC plugs.
For the Turbo 3P1 / 3P2 inverter:
Open the AC plug: First open the cable gland at the back and then push in the
ratchets on the left and right of the plug casing (simultaneously) and unlock
with a suitable tool. Then remove the upper part of the casing from the con-
tact part.
Removing the inverter from the mounting plate
1. Use one hand to press the retaining plate on the mounting plate approx. 5 mm
(0.20 in) towards the mounting surface
2. Use the other hand to push the inverter upwards, far enough so that the retai-
ning plate no longer latches.

3. Lift the inverter with both hands until the hooks on the rear side of the inverter
are free
