Establishing Connections Sizes, Lengths & Bends

Typical Single Protected Enclosure Connections

Helpful Hints

To ensure adequate protective gas flow to the protected enclosure(s), all piping and tubing must be fully reamed.

Precautions must be taken to prevent crimping and other damage to protective gas piping and tubing.

When protecting multiple enclosures with a single enclosure protection system, the enclosures must be connected in series from the smallest to the largest to ensure adequate protective gas flow.

Determining Enclosure Inlet & Outlet Connection Locations

Helpful Hints

If flammable gases are lighter than air, the inlet connection to each enclosure must enter near a bottom corner. The outlet connection, for the required enclosure protection vent or piping to an adjacent protected enclosure, must exit near an extreme opposite top corner. If flammable gases are heavier than air, inlet and outlet connections must be reversed. In all cases, the most prevalent gas must determine the location of inlet and outlet connections.

Electrical Supply Requirements

General Wiring Requirements

WARNING

THIS DEVICE CONTAINS ELECTRICAL PARTS

WHICH CAN CAUSE SHOCK OR INJURY.

All electrical connections, conduit and fittings on the protected enclosure must be suitable for the hazardous location in which they are installed. In addition, all conduit and wire must be installed in accordance with NEC as required and all relevant plant and local codes. Note: Do not use seals on conduit used as a protected "wireway" to supply protective gas to adjacent protected enclosures. The same conduit can be utilized for both electrical and pneumatic service to an adjacent protected enclosure(s), provided the conduit is oversized to allow a minimum free clearance equal to or larger than the pipe size required between multiple enclosures.

Enclosure Power Requirements

The protected enclosure(s) electrical power source must originate from a circuit breaker or fused disconnect suitable for the hazardous location in which it is installed. The switch must be located within fifty (50) (15.2 m) feet of the protected enclosure(s) and the protection system and be properly marked.

Alarm Signal Requirements

The WPSA style pressure switch requires a 120 VAC power supply in addition to the alarm signal. The WPS and WPSA Style system alarm signal may originate from the protected enclosure if the alarm signal is disconnected by the protected enclosure's circuit breaker or fused disconnect as stated in Enclosure Power

Requirements above.

The protected enclosure(s) alarm signal power may also originate from outside of the protected enclosure. In this application, the protected enclosure may be used as a "wireway" to pass alarm signal wiring from the power source to the alarm device, if the wiring is isolated and properly labeled. In addition, appropriate conduit seals must be provided outside of the protected enclosure separately.

Important Note

NFPA 496 requires the use of an alarm or an indicator to detect the loss of safe enclosure pressure. In addition, the NFPA 496 requires that if an indicator alone is utilized, a protective gas supply alarm must also be installed between the last valve in the protective gas supply and the protected enclosure.

Therefore, the protective gas supply to all LPS Style systems must be equipped with the above mentioned protective gas supply alarm. Exception: Systems utilizing an EPSK or GPSK enclosure pressure loss alarm switch accessory will satisfy the above mentioned NFPA requirement.

Typical Enclosure Wiring Methods

In a general sense, protected enclosures should be wired similar to explosion proof enclosures, in accordance with Article 500 of the National Electric Code - NFPA 70.

Single conductor wiring should be placed in rigid metal conduit, seal-flex conduit or other mediums approved for use in the hazardous location surrounding the protected enclosure.

Additionally, NFPA 496 requires the use of approved seals on all pressurized enclosure conduit wiring entries, in accordance with

NFPA 70. Furthermore, the use of an approved seal is simply the most practical way to prevent excessive leakage through conduit connections.

However, while explosion proof enclosures require conduit seals on all cable entries, in accordance with NFPA 70, other methods of sealed cable entries that are suitable for hazardous locations can be used, such as compression glands.

In conclusion, there are two primary goals. First, the installer should ensure that all associated wiring and cable is protected by pressurization or other means, such as explosion proof conduit or intrinsic safety barriers. Secondly, the installer should ensure that all associated conduit and wireways are sealed to conserve protective gas, unless they are used to supply protective gas to other enclosures or devices.

Typical Enclosure Wiring Connections

2 8

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.

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.

Conduit Installation

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.

Set-up Procedure

Helpful Hints

“Safe" pressure, for purposes of this manual, is defined as a minimum .25 inch (6.4 mm) of water column.

Regulator may be in the locked position upon arrival. To adjust regulator, pull handle to outward position.

Carefully insert T-bar valve key to align valve stem tip of both valves. Practice locking and unlocking key in the

RECV valve stem. Practice and familiarization of this process should ease operation of the system.

To test the vent's operation, gently prod the vent flapper open with a soft pointed object, (example: eraser end of a pencil) ensuring that the vent valve works freely. On vertically configured vents, this can be accomplished from within the protected enclosure. Side mounted -90 configured vents can be tested by removing the conduit plug at the bottom of the mounting tee. Multiple operations require only one test per day if enclosure is not opened or left unattended.

Important Notes

T he Rapid Exchange® Control Valve and the Enclosure

Pressure Control Valve are both operated by utilizing the removable T-bar Valve Key supplied with the system. The purge system is shipped with the T-bar Valve Key locked in the Rapid Exchange® Control Valve stem. To remove the Tbar Valve Key, wrap your index and middle finger around the T-Bar and place your thumb firmly against the system face plate. Pull the T-bar Valve Key straight out firmly. This will unlock and free the T-bar Valve Key for use in the

Enclosure Pressure Control Valve stem. When Set-Up or

Operating procedures are complete. Replace the T-bar

Valve Key in the Rapid Exchange® Control Valve stem and push in firmly to lock in position. THE T-BAR VALVE KEY

LOCKS IN THE RAPID EXCHANGE® CONTROL VALVE STEM

ONLY.

Operators must secure wrist or stop watch to manually time Exchange Cycle for all applications.

Pepperl+Fuchs Rapid Exchange® Purging Systems are designed to provide a pre-calibrated and certified volume exchange rate. With the Rapid Exchange® pressure gauge set at 60 psi (4.14 bar) minimum, the model 3003 will accomplish the required volume exchanges at a rate of

ONE MINUTE PER 3 CUBIC FOOT (85 /min) of enclosure volume.

The volume exchange rate is based on a four (4) enclosure volume exchange. Multiply the required exchange time by

2.5 for applications requiring a ten (10) volume exchange for motors. Regardless of enclosure volume or system flow rate. Pepperl+Fuchs requires that operators withhold power to the enclosure while inducing the Class I enclosure volume exchange, for at least five (5) minutes.

Normal exchange times should be doubled if large obstructions block protective gas flow.
