1.3 Wiring
Precaution
▶ Switch off the main power supply and make sure that no current flows in all the circuits before
the wiring work.
▶ Do not touch the real terminal part while the power is on.
▶ Main circuit breaker must be kept in OFF state until all the wiring work is done.
1.3.1 Wiring Specifications
1.3.1.1 Power cable specification
▶ Vinyl-insulated shielding cable KSC 3304 0.9 ~ 2.0 ㎟
1.3.1.2 Terminal connector specification
▶ Use crimping terminal with insulating sleeve proper for M3 screw as shown in the figure.
1.3.1.3 Countermeasures against noise
▶ Noise source
(A) Relay and Electrical contacts
(B) SOLENOID COIL, SOLENOID VALVE
(C) Power Line
(D) Inductive Load
(E) INVERTOR
(F) Rectifier of a Motor
(G) Phase-angle controlled SCR
(H) Wireless communication devices
(I) Welding machines
(J) High-tension magneto-Ignition system
▶ Countermeasures against noise
Notice following guide while wiring work.
(A) The wires of input signal should be apart from power line and grounding line.
(B) Use a shielded wire to guard against a noise from electrostatic induction. Multi-point grounding
should be avoided and connect the shield wire to ground terminal if necessary.
(C) It is effective to make the input wires as a twisted pair to prevent an electromagnetic noise.
(D) When using an auxiliary relay, refer to section 2-1-4-5.
