RJ12 Connectors
As an alternative, inverters RS485 serial connection, both as single units or as daisy
chain, can be performed by means of the RJ12 connectors (See fig. 26).
The wiring is routed through holes, plugged off, located at Inverter bottom (See
Fig.25). Input wiring is routed through one hole and links to one of the RJ12
connectors: it makes no difference if its is no.1 or no.2 since they are connected in
parallel, and signals are thus the same.
The output wiring from the other RJ12 connector goes out from the other hole and
reaches the following unit.
RJ12 No.1
RJ12 No.2
