9 Recommissioning the Inverter
If you have disconnected the inverter from voltage sources (e.g. for configuration purposes) and want
to restart it, proceed as follows.
Requirements:
☐ The miniature circuit-breaker is correctly rated.
☐ The inverter is correctly mounted.
Procedure:
1. Make the protective conductor (PE) connection from
the inverter to the bottom of the enclosure lid.
2. Fasten the enclosure lid to the inverter by evenly tightening the 4 lid screws (torque: 2 Nm).
3. Attach the AC connector.
4. Check the DC connectors for correct polarity and connect them to the inverter
(see Section 6.4.2 "Connecting the PV Array", page 31).
5. Seal all unused DC inputs with DC connectors and sealing plugs.
6. If you are using an ESS, check it for wear (see Section 10).
7.
Risk of fire due to tightening of the ESS screw
Perfect contact between the ESS and the inverter can only be guaranteed if the ESS plug
remains flexible.
• Do not tighten the screw in the plug of the ESS.
