Description
(2) Cable Wiring
● Use our company’s genuine cables for connecting between the actuator
and controller, and for the teaching tool.
● Do not scratch on the cable. Do not bend it forcibly. Do not pull it. Do not
coil it around. Do not insert it. Do not put any heavy thing on it. Failure to
do so may cause a fire, electric shock or malfunction due to leakage or
continuity error.
● Perform the wiring for the product, after turning OFF the power to the
unit, so that there is no wiring error.
● When the direct current power (+24V) is connected, take the great care
of the directions of positive and negative poles. If the connection
direction is not correct, it might cause a fire, product breakdown or
malfunction.
● Connect the cable connector securely so that there is no disconnection
or looseness. Failure to do so may cause a fire, electric shock or
malfunction of the product.
● Never cut and/or reconnect the cables supplied with the product for the
purpose of extending or shortening the cable length. Failure to do so
may cause the product to malfunction or cause fire.

(3) Grounding
● The grounding operation should be performed to prevent an electric
shock or electrostatic charge, enhance the noise-resistance ability and
control the unnecessary electromagnetic radiation.
● For the ground terminal on the AC power cable of the controller and the
grounding plate in the control panel, make sure to use a twisted pair
cable with wire thickness 0.5mm
2
(AWG20 or equivalent) or more for
grounding work. For security grounding, it is necessary to select an
appropriate wire thickness suitable for the load. Perform wiring that
satisfies the specifications (electrical equipment technical standards).
● Perform Class D Grounding (former Class 3 Grounding with ground
resistance 100  or below).
