4.3.2 Power cable
TECNOMAGNETE. supplies. a. suitable. multi-pole.
power.cable.with.a.standard.length.of.four.meters,.
which.prevents.overheating.problems.and.a.voltage.
drop.within.the.rating.of.the.TECNOMAGNETE.mod-
ule,.if.used.in.ordinary.operating.conditions.
Before.using.longer.cables,.always.make.sure.that.
the. cable. section. used. guarantees. a. voltage. drop.
below.1%.
Ordinary.operating.conditions.are.intended.as.inter-
mittent.working.cycles,.with.intervals.of.at.least.one.
minute.between.two.enabling.cycles.
4.3.3 Selecting the correct dimensions for dis-
charge cables
The.discharge.cable.fitted.on.ST200.comprises.four.
leads.suitable.for.the.purpose,.has.a.standard.length.
of. six. meters. and. is. dimensioned. to. prevent. over-
heating.and.the.loss.of.power.on.the.chuck.in.ordi-
nary.operating.conditions.
Ordinary.operating.conditions.are.intended.as.ena-
bling/disabling.cycles.occurring.at.an.interval.above.
1.minute.
Before.using.longer.cables,.always.make.sure.that.
the. cable. section. used. guarantees. a. voltage. drop.
below.1%.
4.3.4 Electric specifications
All.ST200.controllers.are.available.as.single.and.two-
phase. models;. the. maximum. installed. power. for.
each.cycle.is.25.kVA.(cos
ϕ
=0.9).for.two-phase.400V.
plants,.15kVA.for.230V.plants.and.32.kVA.for.480V.
plants.
To.optimally.protect.the.installation,.it.is.necessary.to.
install. a. suitable. magnetothermal. switch. (curve. C).
with.an.I
n
.value.compliant.with.the.rating.specified.
on.the.nameplate.

5.1 ST100
ST100.controllers.are.not.fitted.with.a.specific.ena-
bling.device,.which.may.however.be.ordered.as.op-
tional.(see.Chapter.6.1).
5.2 ST200
The.ST200.controller.has.an.enabling.device.fitted.
on.connector.DB9.situated.on.the.rear.of.the.control-
ler.(PINS.8.and.9).
The.technical.specifications.for.the.contact.are:
•.Voltage.30V,.current.1A
•.Voltage.110V,.current.0.3A
It.is.always.advisable.to.use.an.auxiliary.relay.
Before.using.other.models.of.start.systems,.contact.

by. ST200. is. in. magnetization. mode,. the. enabling.
contact.is.closed..PINS.6.and.7.can.be.connected.to.
the.power.of.the.tool.machine.and.used.to.run.the.
