INSTALLATION AND ELECTRICAL CONNECTION

Check the general condition of the motor before
putting it into operation, with special reference to:
– Good state of preservation of the mechanical
parts, including smooth rotation of shaft and fan
– Good condition of anchoring points (flanges or
feet)
– Good condition of the fan-cover
– Good condition of the surface coating
The characteristics of the application you intend to
use must be compatible with the technical data on
the data-plate and in the catalogue, and with the
prescriptions and indications in this manual. Neces-
INSTALLATION
The indicated prescriptions on installation and me-
chanical connection must be observed.
– Position the motor in its assigned place and se-
cure it with adequate fastening means, respect-
ing its construction shape. The motor can, in
general, be installed in any position. However
protection against penetration of bodies in the fan
compartment must be guaranteed. According to
type of application, penetration can, for example,
occur through the grill of the fan-cover if the fan
is at the top, and through the interspace between
fan-cover and carcass if the fan is facing down-
ward. Such penetration must be countered by an
appropriate guard or by suitably locating the fan
in the installation structure.
– Before connecting mechanical parts to the shaft,
remove the protective layer from the shaft (as
mentioned in "Storage conditions").
– Key the mechanical elements onto the shaft, us-
ing adequate tools only.
– In the event of forced coupling and to avoid dam-
aging the bearings, we advise you to use the
cold-state procedure as shown in Fig. 1 and
Fig. 2.
– For fitting and removing respectively. The cou-
pling tolerances must be inline with ISO286-2
(UNI4399 can be used as a further application
guide), taking into account the construction ge-
ometry of the shaft as indicated in the catalogue.
– For motors with a double output shaft, a rigid cou-
pling on both sides must not be used.
sary checks during installation and commissioning:
– Check if all the electrical terminals connected to
the terminal board are correctly connected (see
item "Electrical connection").
– Make sure that the data on the data-plate match
the characteristics of the feed circuit to which the
motor is connected.
– Observe the criteria of good construction and
preventive technique, local regulations, and the
specifications of the system.
– In case of incompatibility or uncertainty, do not
put the motor into operation or service.
- never operate this product in an explosive
atmosphere.
