storing and installing
induction motors
This document is supplemental to the General «Installation and Maintenance» Instructions, ref. 3770 &
4850
• CONFORMITY
- Our motors conform to standard EN/IEC 60034-1 , and therefore to the Low Voltage Directive 2006/95/EC, which
is demonstrated by their CE marking
• RECEIPT
- Check the state of the motor. If the motor or even the packaging has been damaged, notify your haulage contractor
(if required, renovation cannot be undertaken under warranty).
- Check that the correct motor has been delivered (mounting arrangement, information on nameplate).
• STORAGE
- Place the equipment in a clean dry area, protected from impacts, vibrations, temperature extremes and in an
environment with relative humidity less than 90%.
- Do not remove the rotor blocking device (roller bearings).
- When storing for longer than six months, consult the manufacturer.
• BEFORE INSTALLATION
- Check the insulation resistance of the windings (phase/earth R greater than 10 MΩ) and that the bearings are
working correctly if the motor has been stored longer than six months.
- Drain any condensation water.
- Check motor compatibility with its environment before installation and over its entire operating lifetime.

• MECHANICAL INSTALLATION

- Installation must be performed by qualified personnel.
- Install the motor in the same type of environment (Temperature, Relative humidity, Altitude) as specified in the
order.
- Lifting the motor: when the motor is equipped with lifting rings, these are only to be used for lifting the motor. (The
motor must not be allowed to overturn).
- Mount the motor in its anticipated position, on a firm, level bed to prevent distortion and vibration.
- Ensure that the fixing screws (foot or flange) are tightened to the correct torque. The screw diameter must fit the
fixing holes.
- Ensure that alignment of the mechanical shafts and mounting of the coupling or pulley are carried out correctly.
- Do not knock the shaft or the coupling when mounting, do not damage the seal, do not over-shoot the shoulder
of the shaft.
- Make sure that the motor is properly cooled. The air inlets and outlets must be clear.
- Check that the loads applied to the motor shaft (especially the belt tension) comply with the maximum values
stated in our technical catalogues.
- The condensation water drain holes should be at the bottom of the motor ; dot not install the motor in a position
other than the one stated in the order. When there is no risk to the motor protection, the drain plugs for the
condensation water can be removed.
- Protected motors (IP 23) must be installed under cover.
• ELECTRICAL CONNECTION
- Cables must be connected by qualified personnel, with the power off.
- Select the protection system and the feed cables (the drop in voltage during the starting phase must be less than
3%) according to the details on the identification plate.
