single-phase motors, will require "reforming" following
periods of storage exceeding 1-2 years.
Contact ABB Sales Office for details.
Transportation
Machines fitted with cylindrical-roller and/or angular
contact bearings must be fitted with locking devices
during transport.
Lifting
Lift the motor using the lifting lugs only, if not otherwise
stated in the separate lifting instruction.
The center of gravity of motors with the same frame
may vary due to different outputs, mounting arrange-
ments and auxiliary equipment.
Check that eyebolts or the lifting lugs integrated with the
motor frame are undamaged before lifting. Damaged
lifting lugs must not be used.
Lifting eyebolts must be tightened before lifting. If
needed the position of the eyebolt must be adjusted with
suitable washers.
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 attached to the motor.
Machine weights
Total machine weight can vary within the same frame
size (center height) depending on different output,
mounting arrangements and added features.
The following table shows estimated maximum weights
for machines in their basic versions as a function of
frame material.
The actual weight of all our motors is stated on the
rating plate except the smallest frame sizes.

Installation
Cooling
Normal ambient temperatures should not exceed 40°C
(marine standard +45 or +50°C) if standard performance
is to be achieved. Check that the motor has sufficient
airflow. Ensure that no nearby equipment, surfaces or
direct sunshine, radiate additional heat to the motor. For
more information about higher ambient temperatures and
cooling, see "the Motor Guide" or contact ABB Sales
Office.
Foundation
The purchaser bears full responsibility for preparation of
the foundation.
Metal foundations should be painted to avoid corrosion.
Foundations must be even, and sufficiently rigid to
withstand possible short circuit forces. They shall be
dimensioned as to avoid the occurrence of vibration due
to resonance.
Foundation studs
Bolt the foundation studs to the feet of the motor and
place a 1-to-2 mm shim between the stud and the feet.
Align the motor directly using appropriate means.
Grout the studs with concrete, check alignment and drill
holes for locating pins.
Drain holes
Always check that open drain holes face downward.
In extremely dusty environments, all drain holes should
be closed.
Alignment
Correct alignment is essential to avoid bearing failures,
vibrations and possible fractured shaft extensions.
Slide rails and belt drives
•
Fasten the machine to the slide rails as shown in
figure 2.
•
Place the slide rails horizontally on the same level.
•
Check that the machine shaft is parallel with driven, or
driving, shaft.
•
Any belt must be tensioned according to the supplier's
instructions.
WARNING
Excessive belt tension will damage bearings and
can cause shaft breakage.
Do not exceed the maximum belt forces (i.e. radial
bearing loading) stated in the relevant product
catalogues.
