Motor Weight; Installation And Commissioning; General - ABB M2A Manual De Instalación E Usuario

Ensure that proper lifting equipment is used and that the
sizes of the hooks are suitable for the lifting lugs.
Care must be taken not to damage auxiliary equipment
and cables connected to the motor.

2.4 Motor weight

The total motor weight can vary within the same frame size
(center height) depending on different output, mounting
arrangement and auxiliaries.
The following table shows estimated maximum weights for
motors in their basic versions as a function of frame
material.
The actual weight of all ABB's motors, except the smallest
frame sizes (56 and 63) is shown on the rating plate.

3. Installation and
commissioning
WARNING
Disconnect and lock out before working on the
motor or the driven equipment. Ensure no explosive
atmosphere is present while the work is in progress.

3.1 General

All rating plate values relating to certification must be
carefully checked to ensure that the motor protection,
atmosphere and zone are compatible.
Standards EN 1127-1 (Explosion prevention and protec-
tion), EN 60079-14 (Electrical installations in hazardous
areas (gas)) and EN 50281-1-2/ EN 61241-14 (Electrical
installations in hazardous areas (combustible dust; selec-
tion and installation)) must be respected. Special attention
should be paid to dust ignition temperature and dust layer
thickness in relation to the motor's temperature marking.
Remove transport locking if employed. Turn shaft by hand
to check free rotation if possible.
Motors equipped with roller bearings:
Running the motor with no radial force applied to the shaft
may damage the roller bearing.
Motors equipped with angular contact bearing:
Running the motor with no axial force applied in the right
direction in relation to the shaft may damage the angular
contact bearing.
WARNING
For Ex d and Ex de motors with angular contact
bearings the axial force must not by any means
change direction, because the flameproof gaps
around the shaft change dimensions and may even
cause contact!
The type of bearing is specified on the rating plate.
Motors equipped with regreasing nipples:
When starting the motor for the first time, or after long
storage, apply the specified quantity of grease.
For details, see section "6.2.2 Motors with regreasable
bearing".
When fitted in a vertical position with the shaft pointing
downwards, the motor must have a protective cover to
prevent foreign objects and fluid from falling into the
ventilation openings. This task can also be achieved by
a separate cover not fixed to the motor. In this case the
motor must have a warning label.
