Operation

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.

4 Installation

and Start

(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

(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).
