5. Check the strings for ground faults as described in Section 9.3.1 "Checking the PV Array for
Earth Faults" (page 56).
6. Check the DC connectors for correct polarity and connect them.
To unlock the DC connectors, see Section 7.2 "Opening the Inverter" (page 44).
NOTICE!
Exceeding the maximum input voltage can destroy the inverter.
If the voltage of the PV modules exceeds the maximum input voltage of the inverter, it can
be destroyed by the overvoltage.
This will void all warranty claims.
• Do not connect strings with an open-circuit voltage greater than the maximum input
voltage of the inverter.
• Check the plant design.
DANGER!
Risk of lethal electric shock.
• Do not connect strings with ground faults.
• First, rectify the earth fault in the respective string.
