Safety Information for LR-ZB Series

• 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 disassemble this product. Laser emission from this product

is not automatically stopped when it is disassembled.

• Use with an over current protection device which is rated 30 V or

more and not more than 1 A.

Safety Precautions on Laser Product

• This product employs a semiconductor laser for the light source.

• Use of controls or adjustments or performance of procedures other

than those specified herein may result in hazardous radiation

exposure.

Follow the instructions mentioned in this manual. Otherwise, injury to

the human body (eyes and skin) may result.

• Laser emission from this product is not automatically stopped

when it is disassembled. Do not disassemble this product.

• Do not stare into the beam.
