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 the overvoltage. All warranty claims become void.
• Do not connect strings with an open circuit voltage greater than the maximum input
voltage of the inverter.
• Check the system design.
4. Check the strings for ground faults, as described in section 9.3 "The Red LED Glows
Continuously (Ground Fault)" (page 74).
5. Check the DC plug connector for correct polarity and connect it. To release the plug connectors
see section 7.2 "Opening the Inverter" (page 56).
6. To create the sealing on the inverter, all the DC
inputs have to be closed as follows:
– Insert the blank plugs provided into the
unnecessary DC plug connectors.
Do not insert the sealing plugs into the DC
inputs on the inverter.
– Insert the DC plug connectors with sealing plugs
into the corresponding DC inputs on the inverter.
