Remarks
With glossy objects, the
sensor is to be fastened at
an inclination of
approx. 10° relative to the
object surface.
Operate in accordance with
intended use!
This product is not a safety sensor

protection.
The product may only be put into
operation by competent persons.
Only use the product in accor-
dance with the intended use.
UL REQUIREMENTS
Enclosure Type Rating: Type 1
For Use in NFPA 79 Applications
only.
Adapters providing field wiring
means are available from the manuf-
acturer. Refer to manufacturers in-
formation.
CAUTION – the use of controls or
adjustments or performance of
procedures other than those spe-
cified herein may result in hazar-
dous radiation exposure.
ATTENTION ! Si d'autres disposi-
tifs d'alignement que ceux préco-
nisés ici sont utilisés ou s'il est
procédé autrement qu'indiqué,
cela peut entraîner une exposition
à des rayonnements et un danger
pour les personnes.
