Safety Precautions
■ Precautions for Safe Use
Please comply strictly with the following instructions which are
intended to ensure safe operation of the product.
1. Have the Time Switch installed only by qualified electrical
2. Store the Time Switch within the specified ratings. If the Time
3. Mounting the Time Switch side-by-side may reduce the life
4. Use the Time Switch within the specified ratings for operating
5. Do not operate the Time Switch in any of the following locations.
6. The Time Switch is not waterproof or oil resistant. Do not use it in
7. Do not use the Time Switch in locations subject to excessive dust,
8. Install the Time Switch well away from any sources of excessive
9. Maintain voltage fluctuations in the power supply within the
10.Internal elements may be destroyed if a voltage outside the rated
11.Be sure to wire the terminals correctly and use the correct
Minor injury by electric shock may occasionally occur. Do
not touch any of the terminals while power is being
supplied. Be sure to mount the terminal cover after wiring.
When using a surface-mounting model in an exposed
condition, always install the Y92A-72H terminal cover
(separately purchased) to comply with Electrical
Appliance and Material Safety Law (for Japan).
Minor injury due to explosion may occasionally occur. Do
not use the product where subject to flammable or
explosive gas.
Minor electric shock, fire or malfunction may occasionally
occur. Never attempt to disassemble, modify, or repair the
product or touch any of the internal parts.
Fire may occasionally occur. Tighten the terminal screws
to the rated torque (from 0.98 to 1.17 N·m).
Unexpected operation may occasionally occur.
Before changing times or other settings while power is
being supplied, either turn OFF the power on the load
side or set the output ON/OFF switch to OFF and confirm
the safety of the system.
Minor electric shock, fire, or malfunction may occasionally
occur. Do not allow metal fragments, lead wire scraps, or
shavings from installation work to fall inside the Time
Switch.
If the output relay is used beyond its life expectancy, its
contacts may become fused or there may be a risk of
burning. Use the product within its rated load and
electrical life expectancy. The life expectancy of the
output relay varies considerably according to its capacity
and operating conditions.
Serious injury may occasionally occur due to fire or
explosion of a battery, or leakage from a battery. Never
attempt to short the positive and negative terminals,
recharge, disassemble, deform by applying excessive
pressure, or expose the battery to fire.
