2.2 Operating environment

Make sure that UAM’s operating environment is within the stated specification (temperature, humidity,
vibration, ambient light, etc.)

Do not use or mount UAM near devices that could generate strong electromagnetic waves as it could
affect the operation of UAM.

Do not use or mount UAM in dusty, smoky, or misty environments, or where corrosive substances are
present. Operating under such environments may decrease the detection capacity of UAM.

This product is for indoor use only.
2.3 Installation of UAM

Install UAM on a firm surface or structure to avoid displacement.

UAM should be firmly mounted using the screws (recommended torque for screws is 3N.m.). Shock
and vibration should not loosen the mounting. Detection may fail if actual protection zone differs from
the intended zone due to displacement of UAM.

Safety distance should be determined before installing UAM. User must verify the function of UAM
after installation by placing a test piece at all the positions of protection zone (refer to chapter 4 for the
details on the safety distance calculation for various applications).

When installing the UAM, protective materials such as guards or light curtain should be used to prevent
any passage into the hazardous area.

Reset switch used for interlock, muting and override function should be mounted at a location away
from the protection zone.

Mutual interference can occur when identical UAMs are mounted at the same detection plane. Refer to
chapter 5 for countermeasures to avoid mutual interference.

UAM should be mounted at the location which has sufficient space for maintenance.

Do not add any protective materials such as, glass and transparent cover, in front of the optical window.
This could lead to loss of detection capability of the UAM.

Minimum detectable width varies with the distance. Refer to chapter 10 for details.
2.4 Wiring

Switch off all the power supplies during wiring.

When a converter is used for supplying the power, make sure it fulfills the following requirements.

A rated output voltage within the range of DC 24V±10% (SELV circuit, Category II).

Reinforced insulation or double insulation for the primary and secondary circuit.

Holding time of the output should be above 20ms.

The power supply complies with the requirements of electromagnetic compatibility
regulations (EMC) of the respective country, state and district.

All the input/output signal cables should be installed away from machines power lines and high-
voltage cables.
