7.8.2 Connecting the Ethernet interface
NOTE
The connection plug of an RJ45 cable is larger than the opening of an M25 cable fitting when it is
installed. For this reason, remove the sealing insert before installation and thread the Ethernet cable
outside of the cable fitting through the sealing insert.
NOTE
Use a suitable network cable of at least category 5. The maximum length of a network segment is 100
m. Ensure that the cable is correctly assigned. The Ethernet connection of the inverter supports
auto-sensing. You can use both crossed and 1:1 protectively-wired Ethernet connection cables.
Connecting an Ethernet cable to the inverter
1. Connect the connection cable to Ethernet interface.
2. Attach and tighten the cover of the cable fitting.

7.8.3 Connecting the RS485 bus
NOTE
Ensure that the DATA+ and DATA- wires are properly connected. Communication is not possible if the
wires are reversed!
Different manufacturers do not always interpret the standard on which the RS485 protocol is based
in the same way. Note that the wire designations (DATA- and DATA+) for wires A and B may vary from
one manufacturer to another.

Properties of the RS485 data line
Maximum length of the RS485
bus line The maximum permitted length of the RS485 bus is 1200 m. This length can be
reached only under optimum conditions. Cable lengths exceeding 500m gener-
ally require a repeater or a hub.

nected bus devices 31 inv 1 data monitoring unit
