Recommissioning the Inverter
1. Carry out the necessary tests according to the locally applicable laws, standards and
directives for the correct recommissioning after power assembly replacement. Take the
requirements for component replacements into account (see Section 2.2 "IMPORTANT
SAFETY INSTRUCTIONS", page 7).
2. Ensure that the grounding conductor in the inverter is correctly connected and functions
properly.
3. Mount the upper enclosure lid onto the enclosure and lightly fasten all screws.
4. Tighten the screws of the enclosure lid in the specified sequence (AF4, torque: 6 Nm ±
0.3 Nm).
5. Connect the communication assembly with the
inverter. To do so, plug the ribbon cable to the
communication assembly and lock it.
6. Connect the DC connector to the inverter in its original position.
☑ The DC connectors snap into place.
7. Ensure that all DC connectors are securely in place.
8. Seal all unused DC inputs using the DC connectors with sealing plugs.
9. Insert the lower enclosure lid from above and flip it
down. The screws must protrude from the lower
enclosure lid.
10. 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. Tip: 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.
11. Check the ESS for wear:
