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.
Procedure:
1. Ensure that the grounding conductor in the inverter is correctly connected and functions
properly.
2. 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 8).
3. Attach the enclosure lid as follows:
• Fit 1 conical spring washer to each screw. The
grooved side of the conical spring washer must
face the screw head.
• Position the enclosure lid with the 6 screws on
the enclosure and tighten all six screws in the
sequence 1 to 6 using an Allen key (AF 5)
(torque: 6 Nm ± 0.5 Nm).
☑ The teeth of the conical spring washer press
into the enclosure lid. This ensures that the
enclosure lid is grounded.
4. Connect the DC connector to the inverter in its original position.
5. Seal all unused DC inputs using the DC connectors with sealing plugs.
6. Secure the protective cover using 2 screws and an Allen key (AF 5).
7. Securely plug in the ESS.
8. Switch on the miniature circuit breaker of all 3 line conductors.
