DANGER
Risk of fatal injury due to electric shock
Severe injury or death may result from improper use of the interface connections and failure to
observe protection class III.
› The SELV circuits (SELV: safety extra low voltage) can only be connected to other SELV circuits with
protection class III.
NOTE
When routing the interface connection cable, note that too little clearance to the DC or AC cables can
cause interference during data transfer.
.. Determining the unit type
When connecting, be aware that the arrangement of the interface connections may be dierent from one equip-
ment to another. Check the arrangement of the interface connections with the housing door open.

.. Connecting the fault signal relay
The contact is designed as an N/O contact and is labelled "ERR" or "Relay" on the circuit board.
Maximum contact load
V / A
Connecting the fault signal relay
. Unscrew the cable tting.
. Thread the connection cables through the cable tting.
. Attach the connection cables to the connection terminals.
. Tighten the cable tting.
.. Connecting the Ethernet interface
NOTE
The connection plug of an RJ cable is larger than the opening of an M cable tting when it is
installed. For this reason, remove the sealing insert before installation and thread the Ethernet cable
outside of the cable tting through the sealing insert.
NOTE
Use a suitable category network cable. The maximum length of a network segment is m. Ensure
that the cable is correctly assigned. The Ethernet connection of the inverter supports auto-sensing.
You can use both crossed and : protectively-wired Ethernet connection cables.
