1 ) This system is designed to read and write data (forced on/off) while the programmable

controller is running.

If abnormal data is written to the programmable controller, due to effects of noise, the

programmable controller may malfunction and cause machine trouble or an accident.

Therefore, observe the following cautions.

• Do not lay signal cables near high voltage power cables or put them in the same trunking

duct.

Otherwise effects of noise or surge induction are likely to take place. Keep a safe distance

of more than 100 mm (3.94") from these wires.

• Ground the shield wire or shield of a shielded cable at one point on the programmable

controller. Do not, however, ground at the same point as high voltage lines.

2 ) Cut off phases of power source externally, before installation or wiring work in order to avoid

electric shock or serious damage to the product.

3 ) Replace the provided terminal cover before supplying power and operating the unit after

installation or wiring work in order to avoid electric shock.
