● Wire the each terminal (input, output, solenoid valve
etc.) to the related appliance, after putting off the
main power switch and unplugging the cord.
● Use the controller with rated power supply as
described. Furthermore, keep the fluctuation of
supplied voltage within ±10 ％ .
If the power supply other than the described rated one is used,
the abnormal heat may arise, which may cause the fire.
● Take the earth without fail from the power cord plug or
the back panel of the controller, to prevent the noise
intrusion to the controller and the electric shock.
● Do not carry by holding the cord etc. or do not pull
the plug out by force.
The electric shock or short circuit may arise, which may
cause the fire.
● Do not put the cord near the heat, oil and sharp angle
edge.
● Be careful not to damage the cord by being stepped
on, tripping and getting the extra force.
The electric shock or short circuit may arise, which may
cause the fire.
● Use the solenoid valve by confirming fully the coil
voltage and NC/NO option.
Otherwise, the valve does not work correctly, which may
cause the failure and fire.
● Avoid the installation where it is affected directly by
the vibration
● It is dangerous to put on the unstable stand or shelf,
for fear of dropping off.
● Install apart from the place with loud noise some-
where like the welding machine and so on.
