It indicates a hazardous situation which, if not avoided, could result in

death or serious injury.

It indicates a situation which, if not avoided, could result in product

damage as well as property damage.

• This product is only intended to detect object(s). Do not use this

product for the purpose to protect a human body or part of a human

body.

• This product is not intended for use as an explosion-proof product.

Do not use this product in a hazardous location and/or potentially

explosive atmosphere.

• This product uses DC power. The product may explode or burn if an

AC voltage is applied.

• Do not wire the cable along with power lines or high-tension lines,

as the sensor may malfunction or be damaged due to noise.

• When using a commercially available switching regulator, ground

the frame ground terminal and ground terminal.

• Do not use this product outdoors or in a location in which its
