•
Do not connect two or more timers with only one input contact or transistor
simultaneously.
•
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 filter 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.
