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.

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.
