Motor Weight; Installation And Commissioning; General - ABB ACS800 Serie Manuel D'installation

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 explo-
sive atmosphere is present while the work is in
progress.

3.1 General

All rating plate values relating to certifi cation must be
carefully checked to ensure that the motor protection,
atmosphere and zone are compatible.
Standards EN 1127-1 (Explosion prevention and
protection), EN 60079-14 (Electrical installations in
hazardous areas (gas)) and EN 50281-1-2/ EN 61241-
14 (Electrical installations in hazardous areas (combus-
tible dust; selection and installation)) must be respect-
ed. 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 fl ameproof gaps
around the shaft change dimensions and may
even cause contact!
The type of bearing is specifi ed on the rating plate.
Motors equipped with regreasing nipples:
When starting the motor for the fi rst time, or after long
storage, apply the specifi ed quantity of grease.
For details, see section "6.2.2 Motors with regreasable
bearing".
When fi tted in a vertical position with the shaft pointing
downwards, the motor must have a protective cover to
prevent foreign objects and fl uid from falling into the
ventilation openings. This task can also be achieved by
a separate cover not fi xed to the motor. In this case the
motor must have a warning label.
