t
. − If.the.weigh.cell.is.in.a.hazardous.area/location,.it.must.be.grounded.(i .e .,.an.equipoten-
tial.bonding.conductor.must.be.connected) ..This.connection.should.be.made.by..
a.trained.technician ..The.weigh.cell.is.equipped.with.a.connector.for.the.grounding.con-
ductor ..The.position.is.marked.by.the.symbol.shown.here,.indicating.the.grounding.con-
nection ..
Use.a.stainless.steel.screw.(M6.thread).to.connect.the.grounding.conductor ...
We.recommend.using.a.tooth.lock.washer.to.prevent.the.screw.from.coming.loose ...
The.wire.used.for.the.grounding.conductor.should.have.a.cross-sectional.diameter.of.at.
least.4.mm ,.with.a.suitable.ring.lug.attached ...

The.grounding.cable.must.be.installed.in.such.a.way.that.it.is.not.under.mechanical.
stress.and.so.the.screw.will.not.become.loose ..Connect.all.equipment,.including.periph-
eral.devices,.to.the.equipotential.bonding.conductor .
Connecting the Weigh Cell to AC Power
Before.putting.the.weigh.cell.into.operation,.make.sure.that.the.power.cable.is..
t
correctly.connected.to.the.electrical.outlet;.it.is.especially.important.to.make.sure..
the.grounding.cable.is.attached.to.the.housing.of.the.power.supply ..All.devices.used.
must.be.connected.to.the.equipotential.bonding.conductor.via.the.retainers.provided.on.
each.device ..Installation.must.be.carried.out.by.a.certified.electrician.according.to.the.
valid.standards.of.technology ..
Before.putting.the.equipment.into.operation.for.the.first.time,.make.sure.that.the.
area.of.installation.is.not.hazardous ..If.the.equipment.shows.any.signs.of.mal-
function.as.a.result.of.damage.during.shipment.(display.remains.blank,.display.
not.backlit.even.with.a.weight.readout,.weight.value.not.repeatable,.readout.does.not..
stabilize,.etc .),.disconnect.the.equipment.from.AC.power.and.contact.a.Sartorius.service.

t
. − Lay.both.cables.in.a.manner.that.is.secure.and.protected .
. − Flexible.installation.of.cables.with.threaded.fasteners.can.be.carried.out.on.request ..
Check.the.voltage.rating.and.the.plug.design ..
t
. − If.they.do.not.match.the.rating.or.standard.you.use,.contact.your.Sartorius.office.or.dealer ..
. − Use.only.original.Sartorius.power.supplies:
. − YPC01-Z . . ..(for.use.outside.hazardous.areas/locations)
. − YPC01-X.(for.use.within.hazardous.areas/locations)
To.operate.the.weigh.cell.in.a.hazardous.area.or.location,.please.comply.with.the..
following:.
. – .Currently.valid.standards.and.regulations.for.installation.of.explosion-protected..
. .equipment.in.such.areas.
–.Installations.in.Zone.1.must.be.carried.out.and.checked.by.a.certified.electrician .
Plug.the.female.connector.of.the.blue.intrinsically.safe.power.supply.cable.into.the.
t
socket.on.the.weigh.cell ..Secure.this.connection.by.tightening.the.knurled.collar .
Be.sure.to.connect.the.power.supply.to.the.electronics.module.before.plugging.
the.equipment.in.to.AC.power ...
.
Install.the.power.cable.so.that.it.is.protected.from.damage ...
The.intrinsically.safe.connector.for.the.power.cable.(primary.side).is.not.part.of.
the.standard.equipment.supplied.(open.cable.ends) ...
Connecting.Electronic.Peripheral.Devices..
Make.absolutely.sure.to.unplug.the.weigh.cell.from.AC.power.before.you.connect.
or.disconnect.a.peripheral.device.(display.and.control.unit.or.PC).to.or.from.the.
interface.port ..
