Use
Operating conditions
The machines are intended for use in industrial drive
applications.
Normal ambient temperature limits are -25° to +40°C.
Maximum altitude 1000 m above sea level.
Safety considerations
The machine is intended for installation and use by
qualified personnel, familiar with relevant safety
requirements.
Safety equipment necessary for the prevention of
accidents at the installation and operating site must be
provided in accordance with the local regulations.
WARNING
Small motors with supply current directly
switched by thermally sensitive switches can
start automatically.
Points to observe
1.
Do not use the machine to step on
2.
The temperature of the outer casing of the
machine may be hot to the touch during normal
operation.
3.
Some special machine applications require
special instructions (e.g. using frequency
converter supplies)
4.
Lifting lugs must only be used for lifting the motor.
They must not be used to lift the motor when it is
attached to other equipment.
Handling
Storage
The machine should always be stored indoors, in dry,
vibration free and dust free conditions.
Unprotected machined surfaces (shaft-ends and flanges)
should protected with anti-corrosive paint.
It is recommended that shafts be rotated periodically by
hand to prevent grease migration.
Anti condensation heaters, if fitted, should preferably be
energised.
The characteristics of electrolytic capacitors, if fitted to
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.
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
4
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.
On machines weighing more than 25 kg, the actual
weight is stated on the rating plate.

Installation
oling
Co
Normal ambient temperatures should not exceed 40°C
(marine standard 50°C) if standard performance is to be
achieved. Check that the motor has sufficient airflow.
Ensure that no nearby equipment or surfaces 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.
