Recommissioning the Inverter
If you have disconnected the inverter from all voltage sources (e.g. for configuration purposes) and
want to recommission it, proceed as follows.
Requirements:
☐ The circuit breaker must be correctly rated.
☐ The inverter must be correctly mounted.
Procedure:
1. Connect the DC connectors to the inverter.
☑ The DC connectors snap into place.
2. Seal all unused DC inputs using the DC
connectors with sealing plugs.
3. Ensure that all DC connectors are securely in place.
4. Insert the lower enclosure lid from above and
fold it down. The screws must protrude from the
lower enclosure lid.
5. Tighten all screws of the lower enclosure lid
using an Allen key (AF 3) in the order 1 to 6
(torque: 2 Nm ± 0.3 Nm).
Useful hint: If the screws fall out of the lower
enclosure lid, insert the short screw in the upper
middle hole and the five long screws in the other
holes.
6. If the ESS is used, check it for signs of wear:
