DANGER!
Danger from electrical current
ELECTRICAL SHOCK AND DISCHARGE!
The PV generators/lines may be energised as soon as the PV generators are exposed to light.
Always disconnect all DC and AC cables as follows before starting work on the inverter:
1. Turn the AC circuit breaker to off. Take measures to prevent the system from being uninten-
tionally switched on again.
2. Set the DC circuit breaker on the inverter to position 0. Take measures to prevent the system
from being unintentionally switched on again.
3. Disconnect the DC cable plug connectors according to the manufacturer's instructions.
4. Disconnecting the AC plug from the inverter ⇒ Release safety clip at the front of the AC plug
by depressing it with a suitable object, then pull the plug out.
5. 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).
