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.
☐ All cables must be correctly connected to the terminals.
☐ Unused openings for the DC connection in the inverter enclosure must be closed with UL-listed
type 3R filler plugs.
☐ Unused openings for the Ethernet connection or the communication connection in the inverter
enclosure must be sealed tightly. The factory-mounted filler plugs can be used for that purpose.
Procedure:
1. Ensure that all DC cables are securely in place.
2. Reattach the DC protective cover. Tighten all four
screws with an Allen key (AF 3) in the order 1 to 4
(torque: 3.5 Nm (31 in-lb)).
3. Make sure that the AC cable is routed so that it
cannot be damaged by the partition in the lower
enclosure lid.
4. Insert the lower enclosure lid from above and flip it
down. Make sure that the ribbon cable of the
communication assembly is not clamped and that
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 (17.7 in-lb)). Make
sure that the ribbon cable of the communication
assembly is not clamped. 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.
