15. Reinsert the varistors of the removed power assembly (AST) into the terminal block. Use the
insertion tool for this.
16. Carefully connect the STP-BFS assembly to the power assembly (AST).
17. Plug in all connections on the power assembly (AST). Ensure that the cables are correctly
connected and securely in place.
18. Connect the ribbon cable to the communication assembly and lock it.
19. Recommission the inverter (see Section 7, page 22).
7 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.
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 6).
2. Ensure that the grounding conductor in the inverter is correctly connected and functions
properly.
3. If the DC protective cover has not been attached
yet, reattach it. Tighten all 4 screws with an Allen
key in the order 1 to 4 (AF 3, torque:3.5 Nm).
4. Mount the upper enclosure lid onto the enclosure and lightly fasten all screws.
