Wiring ( continued
)
Separate wiring for power supply for solenoid valves/output and for input
and control of GW/SI
Both single power supply and two power supply systems can be adopted, however, the
wiring shall be made separately ( for solenoid valves/output and for input and control-
ling GW/SI ) for either system.

Branch wiring ( wiring to communication ports )
For wiring with solenoid valves or input devices, connect the branch cable with M12
connector to communication ports A - D.
There are two types of cables different in connector shape ---- straight type and angle
type. As each cable contains power supply wire, there is no need to supply the power
to solenoid valves or input devices individually.
Cable connection
Align the key groove with the
connector ( socket ) of GW unit, plug in
the cable ( plug ).

Tighten the lock nut on cable side by
turning it clockwise by hand.
Confirm that the connector portion does
not move.
NOTE
Mount a waterproof cap on each unused connector of GW unit. The proper use of
waterproof cap can achieve IP65 Enclosure. ( Tightening torque: 0.1Nm for M12 )
