8 Recommissioning the Inverter
If you have disconnected the inverter from all voltage sources and want to recommission it, proceed
as follows.
Requirements:
☐ The circuit breaker must be correctly rated.
☐ The inverter must be correctly mounted.
☐ The DC connectors must be correctly assembled.
☐ The AC cable must be connected correctly.
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 connectors to the inverter. Observe the recorded position of the DC
connectors.
☑ The DC connectors snap into place.
7. Seal all unused DC inputs using the DC connectors with sealing plugs.
