NOTICE
In order to ensure IP 65 protection and the required and declared conformity with
the domestic EMC standard a PHOENIX CONTACT type M12MS SACC-4SC SH plug
and a shielded cable must be used. The outer diameter of the connecting cable can
be max. 8 mm.
Failure to observe this can lead to damage to the inverter and therefore void the
warranty.
NOTICE
Component damage and communication malfunctions
Reversing the RS485 connecting cables and sensor cables results in defects and
malfunctions. If inverters are connected in series, a reversed RS485 can damage
further connected inverters.

Make sure that each of the RS485 connection plugs is connected with the
RS485 receptacle intended for it.

If the connectors are reversed, correctly plug the RS485 connecting cables
immediately.
4.15 Ethernet Interface Connection
The Ethernet interface supports Modbus TCP/IP protocol, and is Sunspec compliant, which can be used for
transmission of data, for example, to a data logger of a remote monitoring system. Daisy-chaining of devices
is not supported. Each inverter must be connected to an ethernet switch, in parallel.
Please use an Ethernet cable with S/FTP design (shielded foiled twisted pair) and Phoenix Contact plug type
Quickon VS-08-RJ45-5-Q/IP67.
