Connect the communication cable with socket-type M12 connector to the
communication connector of GW unit.
Power supply wiring
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 controlling GW/SI. 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.
