9.3 Closing the Inverter
1. Check the DC connectors for correct polarity and
connect them to the inverter.
☑ The DC connectors click audibly into place.
To release the DC connectors (see Section9.2
"Disconnecting the Inverter from Voltage Sources",
page64).
2. Close all unused DC inputs (see Section6.4.4 "Connecting the PV Array (DC)", page45).
This will ensure that the inverter is tightly sealed.
3. Ensure that all DC connectors are securely in place.
4. Attach the lower enclosure lid to the enclosure and
fasten it using the six screws. Use an Allen key
(AF 3) to tighten the screws in the order shown on
the right (torque 2 Nm).
Danger to life due to electric shock.
If the inverter is operated without the lower enclosure lid, the DC connectors could be disconnected
while under load. This could cause arcing.
• Insert the ESS only when the lower enclosure lid is closed.
• Only operate the inverter with the lower enclosure lid closed. This will ensure that the
DC connectors cannot be readily removed.
