For notes for each product, see "Precautions" of each product.
Power supply voltage
Do not use a voltage in excess of the operation voltage range. Appying a voltage in excess of the operation voltage range, or applying AC power (100 V AC or greater) to a DC power model sensor may result in explosion or fire.
Do not short-circuit the load. Explosion or fire may result.
Do not reverse the power supply polarity or otherwise wire incorrectly. Explosion or fire may result.
Connection without a load
If the power supply is connected directly without a load, the internal elements may explode or burn. Be sure to insert a load when connecting the power supply.
Do not use in an environment where there are explosive combustible gases.
