Conduit Installation - Pepperl+Fuchs 1001A Series Installation And Operation Manual

Model 1001A Installation and Operation Manual
Electrical Conduit
1. Choose the location for the enclosure's electrical conduit
connection(s) based on the requirements on page 15,
"Electrical Supply Requirements".
2. Drill and deburr enclosure conduit fi tting holes in the
protected enclosure. Mount the fi ttings.
3. Determine appropriate route for the enclosure electrical and
power alarm signal conduit.
4. Measure, cut and thread conduit, check conduit fi t to insure
proper seating. Fully ream all conduit.
5. Install conduit and tighten all fi ttings to fi tting manufacturers
specifi cations. Secure conduit to appropriate structural
supports as required.
6. Seal all conduit with an approved compound prior to
operation of the protection system.
HELPFUL HINT
It may be impractical to pour all electrical conduit seals
prior to installation in the fi eld. However, all conduit
connections must be sealed for proper testing and
operation of the enclosure protection system. Therefore,
the use of temporary seals such as duct seal or masking
tape for bench or shop testing, prior to fi nal fi eld
installation may be used.

Conduit Installation

WPS & WPSA Style Conduit
WPS and WPSA style systems provide electrical contacts
for audible or visual alarm devices that signal a loss of
protected enclosure pressure. WPS and WPSA style systems
are calibrated to alarm at 0.15" for Class I applications and
0.50" for Class II applications. The switches are suitable
for hazardous (classifi ed) outdoor locations. Wiring must
be installed with a seal and conduit fi ttings suitable for the
area. Alarm circuit power may be derived from the protected
enclosure power source or an intrinsically safe alarm signal
source. All associated alarm devices must be protected by
suitable means (explosion-proof, purged, or intrinsically safe).
