10 ELECTRICAL DATA
Features of the standard motor:
- tropicalised
- equipped internally with a thermal cutout
- IP 55 protection degree
- class F winding
- closed type: asynchronous three-phase 2-speed motors (400/400 V star-
delta connection).
400/400 V - Y ∆ motors are equipped internally with a thermal cutout and
speeds are selected by means of a normal star-delta switch (accessory
CST).
The terminals of the cutouts are connected to the terminal block so that they
can be used as protection in series with the coil of a contactor.
If the internal cutout is not used to protect the motor, it will be necessary to
provide a motor overload cutout set at a current that is 10-15% higher than
the current indicated on the unit rating plate.
Make the electrical connections with the power supply disconnected, in
accordance with current safety regulations. All the wiring must be done by
qualified personnel.
Check that the mains electricity supply is compatible with the voltage shown
on the unit rating plate.
Scrupulously follow the wiring diagram provided, according to the type of
installation.
Each unit requires a switch (
IL ) on the feeder line with a distance of at least
3 mm between the opening contacts, and a suitable safety fuse ( F ).
