Procedure:
1.
Danger to life due to electric shock
• Disconnect the inverter from all voltage sources (see Section 8, page 56).
2. Remove the sealing plugs from the network connection opening on the inverter.
3. Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
4. Attach the conduit to the conduit fitting.
5. Lead one end of the network cable from the conduit into the inverter.
6. When using a self-assembly network cable, assemble the RJ45 connector and connect to the
network cable (see connector documentation).
7. Put the network plug of the cable into one of the
network sockets of the communication assembly.
8. Ensure that the network connector is securely in place by pulling slightly on the cable.
9. If the inverter is installed outdoors, install overvoltage protection.
10. If you would like to establish a direct connection, connect the other end of the network cable
directly to the computer.
11. If you would like to connect the inverter in a local network, connect the other end of the
network cable to the local network (e. g. via a router).
