Motors intended for use in the vertical position
may be delivered on pallets in a horizontal position.
When the motor is pivoted, the shaft must under no
circumstances touch the ground as the bearings could
be irreparably damaged.

If the motor is fitted with a drip cover, allow an additional 50 to 100 mm to avoid
damaging it when the load is swung.
4.2 - Location - ventilation
Our motors are cooled in accordance with method IC 411
(standard IEC 60034-6) i.e. “machine cooled by its surface,
using the ambient fluid (air) flowing along the machine”.
The fan at the non-drive end cools the motor. Air is sucked in
through the grille of a fan cover (which provides protection
against the risk of direct contact with the fan in accordance with
standard IEC 60034-5) and blown along the housing fins to
ensure thermal equilibrium of the motor whatever the direction
of rotation.
The motor is to be installed in an adequately ventilated area,
where the air inlets and exits are free by a value of at least a
quarter of the frame height.
Check that the fan cover bears no impact marks.
Blocking (clogging) the cover grille and the housing fins,
even accidentally, will adversely affect the operation of
the motor and its safety.
With vertical operation with shaft extension downwards, it is
recommended that the motor be equipped with a drip cover to
prevent the entry of any foreign matter.
It is necessary to check that the hot air is not being recycled. If
it is, pipes must be provided for the intake of cold air and
expulsion of hot air, in order to prevent abnormal motor
temperature rise.
In this case, if the air is not circulated by an auxiliary fan, the
dimensions of the pipes must be such that the pressure losses
are negligible compared to those of the motor.
Installation
Possibility of additional external heat
The motor temperature class does not take additional external
heat into account (e.g. pump circulating a hot fluid).
The motor must be mounted in the position specified on
the order, on a base which is rigid enough to prevent
distortion and vibration.
Where the motor feet have six fixing holes, it is preferable to
use those which correspond to the standard dimensions for the
motor power rating (refer to the asynchronous motors technical
catalogue) or failing this to those shown at B2.
Provide easy access to the terminal box, the condensation
drain plugs and, if appropriate, to the grease nipples.
Use lifting equipment which is compatible with the weight of the
motor (indicated on the nameplate).
When the motor is fitted with lifting rings, they are
solely for lifting the motor and must not be used to
lift the whole machine after the motor has been fitted to it.
Note 1: When installing a suspended motor, it is essential
to provide protection in case the fixing breaks.
Note 2: Never stand on the motor.
