Description
(2) Cable Wiring
Ɣ Use our company’s genuine cables for connecting between the actuator and
controller, and for the teaching tool.
Ɣ 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.
Ɣ Perform the wiring for the product, after turning OFF the power to the unit, so that
there is no wiring error.
Ɣ 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.
Ɣ 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.
Ɣ 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
Ɣ 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.
Ɣ 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).
Ɣ Perform Class D Grounding (former Class 3 Grounding with ground resistance
100: or below).
