7 Recommissioning the Inverter
Requirements:
☐ AC overcurrent protection and AC disconnecting unit must be correctly designed.
☐ The inverter must be correctly mounted and closed.
☐ The DC Disconnect must be correctly mounted and closed.
☐ All cables must be correctly connected to the terminals.
Procedure:
1. Place the lower enclosure lid with the six screws onto the
enclosure and tighten them using an Allen key (AF 3) in the order
1 to 6 (torque: 18 in-lbs. (2.0 Nm).
2. Switch on or close all AC disconnecting switches and circuit breakers in the output circuit of the inverter.
3. If an external DC disconnecting switch is available, switch on or close the DC disconnecting switch.
4. Turn the rotary switch of the DC Disconnect to the On position.
☑ The inverter carries out an arc-fault circuit interrupter (AFCI) self test.
☑ The green LED is lit and the display shows the device type, the firmware version, the device names, the
country data set and display language. For communication via Speedwire, the status and version of the
communication module are additionally displayed after the device name.
The inverter is feeding in.
Replacing the communication assembly may cause the inverter firmware to be updated.
5.
In some cases, replacing the communication assembly may result in the firmware of the inverter being
updated. The firmware version of the inverter is displayed during the start-up phase.
• If the firmware version has been updated, check whether the firmware version meets the local
regulations. If a different firmware version is required, it may be necessary to perform an additional
firmware update. For this, contact Service and clarify the next steps.
6. Reassign the previously noted specific settings or values to the inverter via a communication product.
