4.2.2 Power cable
TECNOMAGNETE. supplies. a. suitable. multi-pole.
power.cable.with.a.standard.length.of.two.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.
4.2.3 Selecting the correct dimensions for dis
charge cables
The.discharge.cable.fitted.on.ST100.comprises.suit-
able. leads,. has. a. standard. length. of. three. meters.
and.is.dimensioned.to.prevent.overheating.and.the.
loss. of. power. on. the. chuck. in. ordinary. 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%.
4.2.4 Electric specifications
The.fuses.of.model.ST100.model.are.12.5A.lagged.
fuses.with.a.length.of.20.mm.and.a.diameter.of.5.mm.
(20.x.5.mm).
4.3 Connecting ST200 controllers to the
power supply
4.3.1 Connecting the controller to the power
supply
The.controller.must.be.supplied.with.a.single-phase.
voltage.. The. supplied. multi-pole. cable. has. three.
leads.suitable.for.the.purpose,.two.for.the.phase.and.
neutral. terminals. (or. phase). and. one. for. the. earth.
(yellow/green).
The. controller. cannot. be. powered. from. the. three-
phase. +. neutral. distribution. network. that. supplies.
the.tool.machine.used..If.the.voltage.required.for.the.
controller.is.not.available,.install.a.power.transformer.
with.a.rating.suited.for.the.magnetic.chuck.
