Forced ventilation during operation ensure the good functioning of the
motor taking away the motor heat dissipation.
Make sure that the forced ventilation is kept on for a sufficient time
(according to the motor temperature) after the motor has been turned off.
Air blowers work properly only if rotating in one direction towards the
motor splines. Make sure that the blower is connected in order to have
the correct direction of rotation (see the arrow indicating the direction of
rotation on the fans).
Maintenance
Maintenance operations must be carried out only by qualified personnel.
Inadequate inspections and maintenance can result in personal injury or
property damage.
Maintenance operations must be carried out only by qualified personnel
only after having previously disconnected the equipment or the motor
from the main supply (including any auxiliary and in particular the anti-
condensation heaters). For the single phase motors wait until the
capacitors are discharged.
In case of motors with thermal protectors special precautions should be
taken so that an accidental automatic restart cannot cause any danger.
Don’t use repaired or altered components. Always use brand new OEM
components as replacement parts. Installation and maintenance
personnel must immediately notify all the product defect or anomalies.
The installation and maintenance personnel must NOT allow any motor
use until all possible problems are solved and it’s safe to operate the
motor.
For security reasons the hand release (49) and the hexagonal "T" key
(51) must never be left on the motor but removed and kept by the plant
maintenance responsi ble after every intervention. The hexagonal “T” key
must be used only after having disconnected the motor from the electrical
supply and after having checked that no load is applied to the drive shaft.
