INSTALLATION
4.1 General
Electric.safety.can.be.guaranteed.only.if.the.electric.
system. is. correctly. connected. to. a. grounding. sys-
tem.in.good.working.order,.as.foreseen.by.current.
laws. concerning. electric. safety.. Therefore,. it. is. es-
sential.to.always.verify.this.safety.requirements.be-
fore.starting.the.unit.and.have.the.distribution.sys-
tem. carefully. inspected. by. qualified. personnel. in.
case.of.doubt..TECNOMAGNETE.S.p.A..shall.not.be.
responsible.for.damages.originating.from.the.failure.
to.connect.the.unit.to.an.appropriate.grounding.sys-
tem.
Users.shall.have.to.make.sure.that.the.unit.is.pro-
tected. with. a. differential. magnetothermal. switch.
suitable.to.withstand.the.rated.current.used.by.the.
system..It.is.therefore.necessary.to.install.a.suitable.
protection. with. magnetothermal. switch. (curve. C).
with.a.I
n
.value.compliant.with.nameplate.data.
TECNOMAGNETE. systems. are. permanent-electro.
systems,.which.means.that.they.need.to.be.powered.
only.during.the.short.cycle.phases..This.configura-
tion. is. designed. to. ensure. maximum. safety. in. the.
event.of.power.failure.
TECNOMAGNETE.controllers.use.the.power.supply.
by. means. of. a. sophisticated. partializing. process,.
which.means.that.they.can.be.operated.only.when.
the.machine.is.idle.and.that.they.require.a.rated.cur-
rent.that.is.normally.lower.than.the.one.required.to.
operate.the.machine.on.which.the.magnetic.system.
being.controlled.is.installed.
ATTENTION
Do not perform repeated MAGNETIZATION/DE-
MAGNETIZATION CYCLES
TECNOMAGNETE. systems. are. constituted. by. per-
manent.magnets.and.use.electric.power.only.to.en-
able/disable. the. area. being. machined.. Therefore,.
they. can. be. regarded. “COLD”. magnetic. clamping.
systems.
The. repetition. of. MAGNETIZATION/DEMAGNETI-
ZAZION.cycles.at.very.close.intervals.may.increase.
the. temperature. of. the. magnetic. chuck,. especially.
when.using.controllers.with.DEMAG.NUFLUX.cycle.
It.is.therefore.advisable.to.run.cycles.only.when.nec-
essary.
The.connection.of.the.magnetic.chuck.to.the.power.
supply. must. be. carried. out. by. qualified. personnel.
only.
Check.the.supply.voltage.and.frequency.
The.electrical.supply.to.the.controller.must.be.sin-
gle-phase.230V/400V/480V.(phase.+.neutral).or.two-
phase.(phase.+.phase)..
ATTENTION
ST100.controllers.are.designed.to.operate.with.sup-
ply.voltages.of.230V.50/60.Hz.and.cannot.therefore.
be. used. for. Tecnomagnete. modules. with. lower. or.
higher. ratings.. To. use. different. voltages,. install. a.
transformer.with.a.suitable.rating.(not.above.4.kVA).
or.contact.TECNOMAGNETE.S.p.A..for.assistance.
ATTENTION
ST200. controllers. are. designed. to. operate. with.
supply. voltages. of. 200V. -. 480V. at. 50/60. Hz. and.
can. therefore. be. used,. after. validation,. to. enable.
TECNOMAGNETE. modules. with. different. voltage.
specifications.. To. use. different. voltages,. install. a.
transformer. with. a. rating. compliant. to. that. of. the.
magnetic.chuck.or.contact.TECNOMAGNETE.S.p.A..
for.assistance.
ATTENTION
All.cables.supplied.must.have.a.bending.radius.with.
a.diameter.<10mm.and.a.tension.of.>15N/mm

stallation. must. always. be. performed. by. qualified.
