4.2 Connecting ST100 controllers to the
power supply
4.2.1 Connecting the controller to the power
supply
The controller must be supplied with a single-phase
voltage. The multi-pole cable supplied with the con-
troller has three leads suitable for the purpose.
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.

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 tted 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.
