CSA for Hazardous Locations
When wired in accordance with CEC and this mounting instructions.
Class I, Div. 2, Groups A, B, C and D
Class II, Div. 2, Groups E, F and G
Class III, T4
Enclosure: Type 4/4x
Temp. range: -13° to 176°F (-25° to 80°C)
ELECTRICAL
DO NOT operate an incandescent light bulb as a load.
The current inrush when the bulb is cold can cause a
current overload.
DO NOT operate a proximity sensor directly from a vol-
tage supply without a load. This is a short circuit and can
cause damage. Note: insert a miniature fuse according to
the technical data sheet, if specified.
Concerning Safety... ifm efector makes every effort to build a de-
pendable product, but every product will eventually fail. Therefore,
your equipment must be designed to prevent property damage and
personal injury if our products fail. ifm efector proximity switches
are not designed to be used as stand-alone devices to protect or
guard human life or limb.
WARNING
Explosion Hazard – substitution of components may impair suitabi-
lity of Class 1, Div. 2. Do not disconnect while circuit is live unless
area is known to be non-hazardous.
AVERTISSEMENT
Risque d'explosion - La Substitution de composants peut rendre ce
matérielle inacceptable pour les emplacements de classe I division
2. Ne pas débrancher tant que le circuit est sous tensions, à moins
qu'il ne s'agisse d'un emplacement non dangereux.
CAUTION
Use only ifm efector conduit adapters (U30029, U30030, U30031) or
other CSA ceritifed conduit adapters.
ATTENTION
Utiliser uniquement les adaptateurs tube d'ifm efector (U30029,
U30030, U30031) ou d'autres adaptateurs tube certifiés par CSA.
