■ Be sure to connect to correct polarities, Connecting to a wrong polarity may cause
unexpected malfunction.
■ Use shielded wires and ground the shielding to an independent grounding point.
■ Keep the input circuit wiring as far as possible away from the power and ground circuit.
■ Use a wire having a low conductor resistance and no three-wire resistance differential.
Be sure to ground FRAME GROUND (FG).
Be sure to keep L(Hot) and N(neutral) status connection.
Otherwise, it may result for operation default and defect.
To prevent electric shock, be sure to turn off the controller and the source circuit
breaker before wiring.
7.6 Grounding and Power Cable Connection.
■ Use a thick grounding cable (2 ㎟ or thicker and shorter than 20m) for class-3 grounding or higher
(grounding resistance : 100 Ω below)
■ Be sure to ground from the grounding terminal to an independent grounding point(1 point grounding)
■ Use Vinyl insulation wire 0.9~2.0㎟ (Allowed Rating Voltage 300V max) or higher leveled cable for
power cable connection.
