verify.proper.sequencing .v. After. the. pad-mounted. gear. is. installed,. either:. (1).

destroy. the. extra. set. of. keys. or. (2). make. them.accessi.ble.only.to.qualified.persons ..This.will.main-tain.the.integrity.of.the.key-interlock.scheme ..

v. Key.interlocks.are.not.security.locks.and.are.not..sub-stitutes.for.padlocks .

6 .. OPENING DOORS..Do.not.force.doors.open ..Forcing.a. door. open. can. damage. the. latching. mechanism .. If.optional.key.interlocks.are.provided,.correctly.position.the.interlocks.so.the.doors.can.be.opened .

7 .. CLOSING AND LOCKING DOORS.v. Doors.must.be.securely.closed.and.latched,.with...pad-

13 .. SWITCH POSITION.v. Always. confirm. the. open/close. position. of. Mini-

Rupter.Switches.by.visually.observing.the.position.of.the.switch.blades .

v. Switches.may.be.energized.by.backfeed .

v. Switches.may.be.energized.in.any.position .

14 .. MAINTAINING PROPER CLEARANCE.. Always.maintain. proper. clearance. from. energized.compo.nents .

15 .. FUSE STORAGE.

Operating the Mini-Rupter Switch

The. following. instructions. are. for. operation. of. manual. Mini-Rupter. Switches .. For.Mini-Rupter.Switches.operated.by.Type.PM.Switch.Operators,.refer.to.S&C.Instruction.Sheet.669-515 ..Complete.ratings.for.Mini-Rupters.as.applied.in.S&C.Remote.Supervisory.PME.Pad-Mounted.Gear.are.shown.in.Appendix.B.on.page.22 ..Before.proceeding,.refer.to.the.“DANGER”.on.page.8 ..

1 .. Remove.the.padlock.and.open.the.switch-operating-shaft.access.cover ..See.Figure.3 .

2 .. Remove.the.folding.switch-operating.handle.from.its.storage.pocket.behind.the.access.cover ..Unfold.the.handle.and.slide.it.onto.the.hex.switch-operating.shaft .

. Note.the.switch-position.indicator.which.is.attached.to.the.hex.switch-operating.shaft.and.rests.against.a.stop.in.either.the.open.or.closed.position ..Arrows.indi.cate.switch-open.or.switch-closed.position .

3 .. Rotate.the.handle.in.the.appropriate.direction.to.open.or.close.the.switch,.and.check.the. switch-position. indi.cator. to. verify. that. the. switch. is. in. the. desired. position .. A..window.is.provided.in.the.switch-termina.tion.compartment.to.allow.positive.visual.verification.of.switch-blade.position ..See.Figure.2.on.page.5 .

Ç WARNINGAlways. confirm. the. open/close. position. of. the. Mini-Rupter. Switch. by. visually.observing.the.position.of.the.switch.blades .

4 .. Remove.and. fold. the.switch-operating.handle,.and.return. the.handle. to. its.storage..position ..Then.close.and.padlock.the.access.cover .

Ç CAUTIONDo.not.leave.the.switch-operating-shaft.access.cover.unlocked.if.the.gear.is.left.unattended.by.qualified.persons .

Fuse Access — Opening

S&C.Remote.Supervisory.PME.Pad-Mounted.Gear.is.equipped.with.the.unique.TransFuser.Mounting—a. fuse-handling. mecha.nism. that. is. interlocked. with. the. loadbreak. elbow ..First,.the.elbow.is.removed.to.interrupt.any.fuse.load ..Then,.the.mechanical.interlock.is.actuated,.allowing.operation.of.the.TransFuser.mechanism ..This.permits.access.to.the.fuse.for.quick.and.easy.replacement.of.blown.fuses.with.a.conventional.shotgun.stick ..The.fuse.is.accessible.only.when.it.is.de-energized.and.isolated .

Ç DANGERThe.following.procedures.presuppose.that.the.user.has.supplied.and.installed.load-break.inserts.and.loadbreak elbows .

Open the Mini-Rupter Switches before proceeding if deadbreak inserts and deadbreak elbows are installed, or if company operating procedures and rules do not permit switching with elbows. Failure to open the switches when deadbreak inserts and elbows are used will result in a flashover and serious injury.

Opening the TransFuser Mounting

1 .. Open.the.appropriate.fuse.termination-compartment.door.and.secure.it.with.the.door.holder ..See.Figure.4.on.page.11 ..On.double-door.models,.the.adjacent.door.should.be.closed.and.latched.to.minimize.exposure .

2 .. Using.a.shotgun.stick,.install.a.portable.feedthru.or.standoff.insulator.on.the.parking.stand.that.is.directly.above.the.cable.guide.of.the.elbow.to.be.moved ..This.will.ensure.that. once. the. elbow. is. moved,. the. cable. will. not. interfere. with. the. TransFuser.Mounting .. Using. the. shotgun. stick,. and. following. the. elbow. manufac.turer’s.instructions. for. loadbreak. operation,. remove. the. 200-ampere. loadbreak. elbow.(thus.interrupting.any.load.through.the.fuse.to.be.removed),.and.move.the.elbow.to.the.portable.feedthru.or.standoff.insu.lator ..See.Figure.5.on.page.12 .

Ç DANGERWhen.changing.fuses,.the.200-ampere.interface.need.not.be.covered.since.it.will.be.exposed.only.tempo.rarily ..If.company.operating.procedures.and.rules.require.it,.the.interface.may.be.covered.with.an.insu.lating.protective.cap.without a drain wire ..A.cap.with.a.drain.wire.must.not.be.used ..Operation of the TransFuser mecha-nism will draw the grounded drain wire inside the component compartment close to energized parts which can result in a flashover and serious injury.

Ç WARNINGIf.elbows.are.stored.on.feedthru.or.standoff.insulators.for.an.extended.period.of.time,.cover.the.200-ampere.interface.with.an.insulating.protective.cap.with.a.drain.wire.and.connect.the.drain.wire.to.the.ground.bail ..Failure to connect the drain wire to the ground bail can result in a flashover, injury, and equipment damage.

The.insulated.protective.cap.and.drain.wire.must.be.removed.before.operating.the.TransFuser.mechanism ..Failure to remove the cap and drain wire will in terfere with operation of the mechanism.

1 Fuses must be furnished by others .2 Maximum voltage and current ratings listed apply to the complete pad-mounted gear unit . Consult fuse manufacturer for complete fuse ratings .

3 Holders for 14 .4-kV PME models are rated 14 .4 kV nominal, 17 .0 kV maximum, and 200 amperes maximum . Holders for 25-kV PME models are rated 25 kV nominal, 29 kV maximum, and 200 amperes maximum .

4 Includes adapter when required .

5 All 15 .5-kV fuse types listed—except RTE ELX Current-Limiting Fuses—when used in 14 .4-kV Model PME-4, PME-5, PME-6, PME-9, PME-11, or PME-12 Pad-Mounted Gear furnished with Fault Fiter mount-ings, permit the gear to achieve a 25-kA short-circuit rating . Separable connectors and cables installed in the switch compartments must be rated 25,000 amperes, RMS, symmetrical . In addition, the gear cannot be furnished with optional 200-ampere bushing wells in lieu of 600-ampere bushings at the switch terminals, Catalog Number Suffix “-M4 .”

•. Protection.of.single-phase.transformers.serving.single-phase.loads .

•. Protection.of.three-phase.lateral.circuits.fed.by.single-conductor.shielded.cable.(pro-vided.that.each.trans.former.on.the.lateral.is.individually.fused.so.that.the.current-lim-iting.fuse.serving.the.lateral.will.not.be.required.to.clear.secondary.faults) .
