Installing the Communication Assembly

1. Insert the new communication assembly in the DC Connection Unit.
2. Fasten the communication assembly using the three screws included in the scope of delivery
(TX20, torque: 3.5 Nm ± 0.5 Nm (30.98 in-lb ± 4.43 in-lb)).
3. Insert all plugs into the respective sockets of the communication assembly.
4. If necessary, install the communication modules (see the manual of the communication
module).
5. Mount the enclosure lid in front of the DC-Connection Unit (see Section 6, page 14).
6. Commission the inverter without integration into the local network (see inverter manual). It can
take up to 15 minutes before the new assembly has synchronized with the inverter. An inverter
update of the inverter can also be carried out.
7. Update the inverter network settings and integrate the inverter into the local network (see
inverter manual).
8. Stick the label provided in the scope of delivery over
the existing label next to the type label.
9. If necessary, reconfigure the communication modules. For this, start the installation wizard via
the user interface of the inverter (see manual of the inverter). If there is a QR code on the
enclosure lid for easy connection to the user interface via WLAN, it can no longer be used
after the replacement of the communication assembly.
