8 Recommissioning the Inverter
7. Connect the DC connector to the inverter in its original position.
☑ The DC connectors snap into place.
8. Ensure that all DC connectors are securely in place.
9. Make sure that the AC cable is routed so that it cannot be damaged by the partition in the
lower enclosure lid.
10. Seal all unused DC inputs using the DC connectors with sealing plugs.
11. Insert the lower enclosure lid from above and flip it
down. The screws must protrude from the lower
enclosure lid.
12. Tighten all 6 screws in the order 1 to 6 (hex socket,
AF3, torque: 2.0 Nm) By tightening the screws in
the prescribed order, you avoid warping the
enclosure lid, which would keep it from sealing
correctly. Tip: If the screws fall out of the lower
enclosure lid, insert the long screw into the lower
middle hole and the 5 short screws into the other
holes.
13. Insert the DC load-break switch firmly into the
intended opening on the inverter. During this
process, the DC load-break switch must still be in
position O and aligned so that the screws are
positioned over the threads.
