Power supply wiring
2
Connect the power supply connector cable to the power supply connector of GW unit.
There are two types of cables different in connector shape ---- straight type and angle
type. With this cable, the power is supplied to the output devices such as solenoid valve,
and the input devices such as sensor, and for control. Therefore, there is no need to
supply the power to other units individually.
When selecting the power supply, refer to "Handling precautions" ( page 3 ) in this manual.
Cable connection
Aligning the key groove with the power supply
connector ( plug ) of GW unit, plug the power supply
cable ( socket ).
Tighten the lock nut on cable side by turning it
clockwise by hand.
Confirm that the connector portion does not move.

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 controlling
GW/SI ) for either system.
