4. Check the strings for ground faults, as described in section 9.3.1"Checking the PV Array for a
Ground Fault" (page52).
5. Check the DC connectors for correct polarity and connect them.
To unlock the DC connectors see section 7.2"Opening the Inverter" (page39).
6. In order to seal the inverter, all the DC inputs that
are not required have to be closed as follows:
– Insert the provided sealing plugs into the DC
connectors that are not needed.
Do not insert the sealing plugs into the DC
inputs on the inverter.
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 ground fault in the respective string.
