4. Check the strings for ground faults as described in section 9.3.1 "Checking the PV Array for
Ground Faults" (page 74).
5. Check the assembled DC plug connectors for correct polarity and connect them to the inverter.
☑ The DC connectors click audibly into position.
To unlock the DC connectors, see section 7.2 "Opening the Inverter" (page 56).
6. In order to seal the inverter, all the DC inputs that are not required have to be closed with DC
plug connectors and sealing plugs:
– For unused DC connectors, push down the
terminal clamp and push it onto the cable gland.
NOTICE!
Destruction of the inverter due to overvoltage!
If the voltage of the PV modules exceeds the maximum input voltage of the inverter, it can
be destroyed by 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.
Sealing plugs
• Do not insert the sealing plugs directly into the DC inputs of the inverter.
