tions.against.fire.or.explosion.
•. When.working.in.hazardous.environments,.always.
exercise.appropriate.safety.precautions.
•. Be.sure.O-rings.and.seals.are.kept.in.good.repair..
•. When.applying.power,.use.DC.power only!

INSTALLATION
CAUTION
Installation should be performed only by qualified
personnel, and in accordance with local governing
regulations.
The.following.installation.guidelines.are.separated.by.
meter.series.and.mounting.type.
Precision G Series:
•. Local –.The.GG510.Pulse.Out.with.Display.mounts.
directly.to.the.1-inch.MNPT.conduit.connector.
•. Remote –.The.GG500.Pulse.Out.with.Display.con-
nects. via. an. output. cable. as. shown. in. the. Wiring.
Diagram.
Industrial Grade G2 Series:
•. Local –.The.GG510.Pulse.Out.with.Display.requires.
the.GPI.Conduit.Connector.Kit.(Part.#113437-01).for.
local.mounting.to.the.G2.series.meter.
•. Remote –.The.GG500.Pulse.Out.with.Display.con-
nects. via. an. output. cable. as. shown. in. the. Wiring.

Commercial Grade A1 Series:
•. Local –.The.GG510.Pulse.Out.with.Display.requires.
the.GPI.Conduit.Connector.Kit.(Part.#113437-01).for.
local.mounting.to.the.A1.series.meter.
•. Remote –.The.GG500.Pulse.Out.with.Display.con-
nects. via. an. output. cable. as. shown. in. the. Wiring.

GM Oval Gear Series:
•. Local –. The. Pulse. Out. with. Display. is. mounted.
directly.to.the.oval.gear.meter.housing.
•. Remote –.The.GG500.Pulse.Out.with.Display.con-

Remote Installation
Choose.a.mounting.location.suitable.for.the.Display..The.
ideal.mounting.location.is.where.the:
•. Flowmeter.is.as.close.as.possible.
•. Mounting.surface.has.minimal.vibration.
•. Ambient.temperature.is.0°.F.to.+140°.F.(-18°.C.to.
+60°.C).
•. Cable.lengths.are.minimal.
Avoid.mounting.locations.where.the.Display.is:
•. Subject.to.constant.exposure.to.water.or.other.liquids.
(occasional. low-pressure. splashing. will. not. harm.
unit).
•. Subject.to.>.5g.shock.loading.
•. Facing.the.sun.directly.for.long.periods.of.time.
Mount.the.GPI.Display.Remote.using.bolts,.screws.or.
standard.U-bolts.for.pipes..Mounting.options.include:
•. Wall
•. Pipe
•. Meter.(1-inch.FNPT.conduit.connection.required).
Some.products.come.with.20.feet.of.shielded.cable..GPI.
offers.an.optional.cable.kit.with.100.feet.of.cable.(see.
spare.parts.list)..When.wiring.longer.lengths.of.cable,.
be. sure. to. connect. the. shield. to. LOCAL-COM. only!.
(Multiple. shield. connections. may. cause. ground-loop.
problems..Some.trial.and.error.may.be.needed.because.
of.the.wide.variety.of.user.conditions..
Try.to.keep.cable.lengths.short..Individual.installation.
sites. vary. widely,. contact. GPI. Customer. Service. with.
questions.regarding.your.specific.needs.
WIRING
This.manual.refers.to.various.models.of.GPI.flowmeters..
Determine.what.type.of.input.the.electronics.will.receive.
and.what.type.of.output,.if.any,.you.require..If.the.unit.is.
not.already.wired,.use.the.diagrams.found.in.the.wiring.
diagrams.section.to.correctly.wire.the.system.

Connecting the Equipment

1.. Remove.the.faceplate.by.removing.the.four.corner.
screws.
2.. Attach. wiring. from. your. equipment. according. to.
the. following. terminal. connections. and. wiring. in-
structions,.depending.on.your.circumstances..(See.
Terminal.Connections.below)
The. display. may. be. powered. by. battery,. externally.
powered.or.both..When.both.are.used.(external.power.
terminal.as.primary.with.the.battery.terminal.as.back.up).
the.batteries.should.last.up.to.5.years..Connection.and.
disconnection.of.either.power.input,.while.the.other.is.
active.will.not.interrupt.operation.of.the.display.
