▶ FG wiring
Vinyl-insulated wire(2.0 ㎟ (KSC 3304)) must be used. It must be grounded at 3 points or
more with 100 Ω or less resistance.
▶ Power connection
Vinyl-insulated wire(0.9 - 2.0 ㎟ (KSC 3304)) must be used.

Too much noise may lead to damage or malfunction to the device.
Use line filter to remove the noise.
Caution
Inductive load(L) including motor, solenoid, and external relay may lead to malfunction.
The CR filter for AC circuit and the diodes for DC circuit should be connected in parallel
with the inductive load
Caution
Input wire must use shielded cable and be wired with certain distance from
the power and ground circuits. RTD sensor must be 3-wire type with the same wiring
resistance.
Caution
•Enclosure must be grounded at 3 points or more(100 Ω or less of grounding resistance)
using 2 ㎟ or bigger cable.
•Input signal and output lines must be of shielded cable with 1 grounding point.
•Thermoresistor input must be wired with no resistance difference between 3 wires.
•Input/output signal line must be isolated from power line.
•To use current input, attach 250 Ω 0.1 % resistor at both ends of input terminal.
Caution

Fig. 2) Connection of relay
Before wiring, disconnect the power.
Do not touch a terminal because it may lead to electric shock.
