• Put the AC+DC switch14 in the OFF (open) position.
Under this condition the wiring box has hazardous voltages, identi-
ed by the colours RED (up to 1000 V DC) and ORANGE (400V AC).
Green areas may be freely accessed.
• Disconnect any power supplies that may be connected to the congur-
able relay.
• Disconnect input strings.
The OFF switch may be used to disconnect the strings without any dan-
ger of creating an arc discharge.
Under this condition the wiring box has hazardous voltages, identi-
ed by the colour ORANGE (400V AC). Green areas may be freely
accessed.
• Disconnect grid voltage (by switching off the protective device up-
stream of the inverter) .
Under these conditions the wiring box does not have any hazard-
