2.2 Wiring
2.2.1 Caution for Wiring
1) Do not lay signal cable near to high voltage power cable or house them in the same trunking
duct. Effects of noise or surge induction may occur. Keep signal cables a safe distance of
more than 100 mm (3.94") from these power cables.
2) Ground the shied wire or the shield of a shielded cable at one point on the programmable
controller. Do not, however, ground at the same point as high voltage lines.
3) The terminal screws of the 32DP-IF are M3.5 (0.14"), therefore the crimp style terminal (see
drawing) suitable for use with these screws should be fitted to the cable for wiring.
Figure 2.3: Crimp Terminals
4) The terminal tightening torque is 0.5 to 0.8 N•m. Tighten securely to avoid malfunction.
5) Cut off all phases of power source before installation or performing wiring work in order to
avoid electric shock or damage of product.
6) Replace the provided terminal cover before supplying power and operating the unit after
installation or wiring work, in order to avoid electric shock.
