Cautions during Use

1. Follow instructions in ‘Cautions during Use’. Otherwise, It may cause unexpected

accidents.

2. When supplying or turning off the power, use a switch or etc. to avoid chattering.

3. Install a power switch or circuit breaker in the easily accessible place for supplying
or disconnecting the power.

4. In order to avoid leakage current owing, connect resistance and condenser as

(Figure 2).

If connect as (Figure 1), it may cause malfunction due to leakage current.

5. Keep away from high voltage lines or power lines to prevent inductive noise.

In case installing power line and input signal line closely, use line lter or varistor at

power line and shielded wire at input signal line.
Do not use near the equipment which generates strong magnetic force or high
frequency noise.

6. Change setting time(T1), Y-Δ switching time or etc. after turning off the power of the

timer.
