Recommissioning the Inverter
Qualified person
If you have disconnected the inverter from all voltage sources (e.g. for configuration purposes) and want to recommission it, proceed as follows.
Requirements:
- The circuit breaker must be correctly rated.
- The inverter must be correctly mounted.
Procedure:
- Insert the lower enclosure lid from above and fold it down. The screws must protrude from the lower enclosure lid.
- Tighten all six screws in the lower enclosure lid with an Allen key (AF 3) in the order 1 to 6 (torque: 2 Nm ± 0.3 Nm).
- Switch on the circuit breaker of all three line conductors.
- Turn the DC load-break switch to the position I.
- The green LED is glowing and the display alternates between the firmware version, the serial number of the inverter, the NetID, the configured country data set and the display language.
- Once the DC input voltage is sufficiently high and the grid connection conditions are met, the inverter will start operation.
- Eliminate the error ( > Troubleshooting).
The green LED is flashing?
Possible cause of error: the DC input voltage is still too low or the inverter is monitoring the utility grid.
The red LED is glowing and an error message and event number appear in the display?
