Connect the inverters to each other
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 inverter.
Procedure
•
Wiring the data cable to the "Phoenix Contact Type M12MS SACC-4SC SH“ according to the manu-
facturer's instructions.
•
Insert one plug into the OUT (X14B) socket of inverter 1.
•
Insert the other end of the wire into the IN socket (X15B) on inverter 2.
•
Connect the other inverters to each other in the same way.
•
Terminate in the last inverter.
On the sockets "RS485 OUT" with Phoenix contact type M12MS SACC-4SC SH bridge the connec-
tions PIN1 to PIN2 and PIN3 to PIN4.
•
Close inverters.
