4. Wiring

CAUTION

■ Before carrying out wiring, turn off the power to the controller and check that the cables to be

connected are not alive with a tester or the like because there is a possibility of electric shock.

Personnel who have basic electrical knowledge and practical experience must carry out wiring.

■ The controller must be wired directly from circuit breaker output on inside of temperature &

humidity Chamber for avoid damage of controller or temperature & humidity Chamber.

4-1. How to connect wires

4-1-1. Applicable power source cable : Vinyl insulation cable KSC 3304 0.9~2.0 ㎟

4-1-2. Applicable tightening torques

Please use-tightening torque with insulating sleeve for M3.5 screws as shown in the following Figure:

4-1-3. Noise rejections

■ Reason making noise

(1) Relay and relay contact point (2) Solenoid coil, solenoid valve

(3) Power source line (4) Inductive load

(5) Invertors (6) Commentators of motor

(7) Phase-angle SCR (8) Wireless communication

(9) Welder (10) High-tension igniter, etc.

■ Solutions

When wiring, comply with the following to protect the controller from noise sources:

(1) Keep away the cables to the input circuit from the power supply

circuit or the grounding circuit as much as possible.

(2) Using a shielded cable is effective in avoiding noise from electrostatic induction. Connect a

shielded cable to the grounding terminal as required. Avoid two-point grounding.

(3) To avoid noise from electromagnetic induction, it is relatively

effective to mutually twist the input cables at regular short intervals.
