To ensure safety, always observe the following precautions.

Wiring

Power Supply Voltage

Do not use a voltage in excess of the operating voltage range.
Applying a voltage in excess of the operating voltage range, or applying AC power (100 VAC or greater) to a DC Sensor may cause explosion or burning.

Load Short-circuiting

Do not short-circuit the load.
Doing so may cause explosion or burning.

Incorrect Wiring

Do not reverse the power supply polarity or otherwise wire incorrectly.
Doing so may cause explosion or burning.

Connection without a load

If the power supply is connected directly without a load, the internal elements may burst or burn. Be sure to insert a load when connecting the power supply.

Operating Environment

(1)Do not use a Sensor in an environment where there are explosive or inflammable gases.

(2)Do not use the Sensor in environments where the cables may become immersed in oil or other liquids or where liquids may penetrate the Sensor. Doing so may result in damage from burning and fire, particularly if the liquid is flammable.
