Connect using
•
a 2-wire shielded data cable and
•
4-pin Phoenix Contact Connection plug type "M12MS SACC-4SC SH“ (two plugs included with the inverter).
•
Where to connect: RS485 sockets on the bottom of the inverter.
The RS485 IN and OUT sockets are each double connections so that the wiring can be continued to the next inver-
ter.
Procedure
1. Wiring the data cable to the "Phoenix Contact Type M12MS SACC-4SC SH“ according to the manufacturer's
