Electrical Connection
NOTICE!
Overvoltage can destroy the inverter.
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.
4. Check the strings for ground faults as described in section 9.3.1 "Checking the PV Array for
Ground Faults" (page 71).
5. Connect the assembled DC connectors to the inverter.
☑ The DC connectors click audibly into position.
6. In order to seal the inverter, all the DC inputs that are not required have to be closed with
DC connectors and sealing plugs:
Sealing plugs
• Do not plug the sealing plugs directly into the DC inputs on the inverter.
– For unused DC connectors, push down the
clamping bracket and push it onto the cable
gland.
