■ Precautions for Safe Use

Please observe the following precautions for safe use of this product.

Environmental Precautions

Store the Timer within specified ratings. If the Timer has been stored

at -10°C or lower, let it stand for 3 hours or longer at room

temperature before turning ON the power supply.

Use the Timer within the specified ratings for operating temperature

and humidity.

Do not operate the Timer in locations subject to sudden or extreme

changes in temperature, or locations where high humidity may result

in condensation.

Do not use the Timer in locations subject to excessive dust, corrosive

gas, or direct sunlight.

Do not use the Timer in locations subject to vibration or shock.

Extended use in such locations may result in damage due to stress.

Install the Timer well away from any sources of static electricity, such

as pipes transporting molding materials, powders, or liquids.

Usage Precautions

Install a switch or circuit breaker that allows the operator to

immediately turn OFF the power, and label it to clearly indicate its

function.

Pay careful attention to polarity to prevent wrong connections when

wiring terminals.

Internal elements may be destroyed if a voltage outside the rated

voltage is applied.

Maintain voltage fluctuations in the power supply within the specified

range.

The Timer uses a transformerless power supply. Do not touch the

input terminals while the supply voltage is being applied, otherwise

an electric shock may occur.

CAUTION

Indicates a potentially hazardous

situation which, if not avoided, may

result in minor or moderate injury or in

property damage.
