8 Recommissioning the Inverter
Requirements:
☐ The inverter must be correctly mounted.
☐ The DC connectors must be correctly assembled.
☐ The AC cable must be connected correctly.
Procedure:
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. Reattach the DC protective cover. Tighten all 4
screws in the order 1 to 4 (hex socket, AF3,
torque:3.5 Nm).
4. Connect the communication assembly with the
inverter. To do so, plug the ribbon cable to the
communication assembly and lock it.
5. Connect the DC connector to the inverter in its original position.
☑ The DC connectors snap into place.
6. Ensure that all DC connectors are securely in place.
7. Make sure that the AC cable is routed so that it cannot be damaged by the partition in the
lower enclosure lid.
8. Seal all unused DC inputs using the DC connectors with sealing plugs.
