09System Mounting

IMPORTANT NOTESThe system should be mounted at EYE LEVEL.

Care must be taken to ensure the system and all protruding components are clear of all enclosure accesses (doors and covers) and conduit, pipe, tubing or cable entries.

LH, RH, TM, BM and WM configurations are intended for mounting adjacent to the protected enclosure.

LH, RH, TM & BM configurations are also suitable for 2" schedule 40 pipe mounting.

Determine the mounting configuration of your system using the diagrams on pages 9 & 10.

Remove and save the manila envelope (containing the enclosure warning nameplate) which may be taped to the outer surface of the mounting flange.

Although all systems are factory tested and calibrated, we strongly suggest a bench test of basic functions prior to installation.

IMPORTANT NOTESFor proper moisture drainage of the Type 7 enclosure, the installer must 1) move the Type 7 breather drain to one of the bottom conduit entrances or 2) use drain seals on all conduit connected to the bottom two conduit entrances.

The Type 7 breather drain is not provided or required with PM configurations.

Top two conduit entrances will be dedicated for Intrinsic Safe wiring ONLY when the EPCU is supplied with Pepperl+Fuchs' optional ISB intrinsic safety barriers.

Set-up Procedure

Model 2002 Rapid Exchange Purging Set-up1.Closetheenclosurepressurecontrolregulator(allstyles)

andRapidExchangecontrolvalve(STDStyleonly)fullybyturningclockwise(CW).

2.ConnecttheinertgassupplytothesystemsupplyInletandsettheRapidExchangepressuregaugeto60psi.

3. Temporarilyconnecta0-5inchwatercolumnpressuregaugeormanometertotheprotectedenclosure.

4.Checkoperationofenclosureprotectionventasdetailedabove.See"ImportantNotes."

5.Sealenclosure(s)andadjustenclosurepressurecontrolvalvebyopeningslowlycounterclockwise(CCW)toseta“safe”pressureontheenclosurepressuregauge.

Note:Ifpressuresettingisdifficulttostabilizeorset,(seepage25,“TroubleshootingProcedures”).

IMPORTANT NOTESRegardless of any condition, the Type X Rapid Exchange system is designed to automatically withhold power to the protected enclosure while inducing Rapid Exchange®, for at least five (5) minutes. Normal exchange times should be doubled if large obstructions block inert gas flow.

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 pipe plug at the bottom of the mounting tee. Multiple operations require only one test per day if enclosure is not opened or left unattended.

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 (motors).

The start-up instructionnameplate exchange time slot will feature the standard factor for this system "ONE MINUTE PER CUBIC FOOT", but the unit may feature a set of direct factor nameplates with self-adhesive backing such as “TEN MINUTES”, for application to the start-up instructions, dependent on how the system was specified and purchased. Field modification of this nameplate, to show a direct factor, is acceptable as noted above if the method used to mark the nameplate does not deface the instructions listed. Materials used for the marking must be indelible and withstand prevailing environmental conditions.

Operating Sequence

WARNING! Do not exceed a “safe” pressure with the enclosure pressure control regulator.

Operators must follow step-by-step sequence of the start-up instructions nameplate on the protection system.
