Installation Guide and Manual

Conduit Installation

Electrical Conduit

1. Choose the location for the enclosure's electrical conduit

connection(s) based on the requirements on page 49,

"Electrical Supply Requirements".

2. Drill and deburr enclosure conduit fitting holes in the

protected enclosure. Mount the fittings.

3. Determine appropriate route for the enclosure electrical

and power alarm signal conduit

4. Measure, cut and thread conduit, check conduit fit to

ensure proper seating. Fully ream all conduit.

5. Install conduit and tighten all fittings to fitting

manufacturer’s specifications. Secure conduit to appropriate

structural supports as required.

6. Seal all conduit with an approved compound prior to

operation of the protection system.

WPS Style Conduit Connection Parts

WPS & WPSA style systems provide electrical contacts for audible

or visual alarm devices that signal a loss of protected enclosure

pressure. They are calibrated to alarm at 0.15” (3.8 mm) for Class

I applications. The switches are suitable for hazardous (classified)

outdoor locations. Wiring must be installed with a seal and

conduit: fittings 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).

WPS Style Conduit Connection Parts

Fitting Kits Can Be Bebco Furnished

1. For EXP pressure loss alarm switch connected to an

enclosure mounted alarm, one (1) LCK (L fitting Conduit Kit)

or equivalent conduit elbow, coupling and seal fittings.

2. For EXP pressure loss alarm switch connected to a remote

mounted alarm, one (1) TCK (T fitting Conduit Kit) or

equivalent conduit tee, coupling and seal fittings.

3. One (1) lot 150# rating 1/2" galvanized or aluminum pipe.

Helpful Hint

It may be impractical to pour all electrical conduit seals prior to

installation in the field. 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 final

field installation may be used.
