● Recommended specification for electric cable: Vinyl insulated electric cable KSC3304 0.9~2.0mm2
● Recommended specification for terminal: Use the pressed terminal with insulation sleeve which is proper to the M3 screw as shown in [Fig. 1].
● Source of noise
(A) Relay and contact point
(B) Solenoid coil and solenoid valve
(C) Electric power line
(D) Induced load
(E) Inverter
(F) Commutator in motor
(G) SCR for controlling the phase angle
(H) Wireless communication device
(I) Welding machine
(J) High pressure ignition device and etc
● Solution for noise
(A) Make the wiring with caution for the following points from the noise creation source.
(B) Make the wiring for the input circuit with placing the gap from the power circuit and ground circuit.
(C) Use the shield line for the noise from the electrostatic induction.
(D) Connect the shield line to the ground terminal according to the necessity not to make the 2 point ground.
(E) Make the wiring in tight twisting for the noise from the electric induction.
1-3. Wiring
● Make the wiring after checking whether the wiring cable is applied for current with tester by switching off the main electric power in every
supplied instrument.
● Never contact to the terminal because of the risk of electric shock during application of the current (Electric power on).
● Make the wiring after switching off the main electric power certainly.
