7.3 Closing the Inverter
1. Tighten the enclosure lid with all screws and the
corresponding conical spring washers in the
sequence depicted on the right (torque: 6 Nm).
The toothing of the conical spring washers must
point toward the enclosure lid.
The scope of delivery of the inverter includes
another spare screw and conical spring washer.
2. 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).
3. Close all the DC inputs that are not needed as described in section 5.4.4 "Connecting the PV
Array (DC)" (page 34) to seal the inverter.
4. Ensure that all DC plug connectors are securely in place.
DANGER!
Danger to life due to enclosure lid carrying voltage!
The grounding of the enclosure lid is ensured by the conical spring washers.
• Fasten the conical spring washers for all 6 screws with the toothing facing toward the
enclosure lid.
