11 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 inverter must be correctly mounted.
☐ The DC connectors must be correctly assembled.
☐ The AC cable must be connected correctly.
Procedure:
1. Make sure that the AC cable is routed so that it cannot be damaged by the partition in the
lower enclosure lid.
2. Connect the assembled DC connectors to the inverter.
☑ The DC connectors snap into place.
3. Seal all unused DC inputs using the DC connectors with sealing plugs.
4. Insert the lower enclosure lid from above and
fold it down. The screws must protrude from the
lower enclosure lid.
5. Tighten all six screws with an Allen key (AF 3) in
the order 1 to 6 (torque: 2.0 Nm ± 0.3 Nm). By
tightening the screws in the prescribed order,
you avoid warping the enclosure lid, which
would keep it from sealing correctly.
Useful hint: If the screws fall out of the lower
enclosure lid, insert the long screw into the lower
middle hole and the five short screws into the
other holes.
