1.4 Preliminary Checks

Users should check all documentation quoted in the
standard technical information in conjunction with data
concerning standards on explosion-proofi ng, such as:
a) Gas group
Industry Gas group
Explosive IIA
atmospheres
IIB
other than mines
IIC
b) Marking temperature
Temperature class T1 T2
Max. temperature °C 450 300 200 135 100 85
Max. temperature 400 250 155 90
rise of surface K
at 40°C
Max. temperature rise of surface is considered to be the
surface inside the motor (rotor) for temperature classes
T1, T2 and T3 and the outer surface of the motor (frame
and/or end shields) for other temperature classes.
It should be noted that the motors are certifi ed and
classifi ed according to their group. This is determined
by reference to the ambient gas or dust atmosphere
and by the marking temperature, calculated as a func-
tion of the ambient temperature of 40°C.
If the motor is to be installed in ambient temperatures
higher than 40°C or at altitudes higher than 1000 me-
ters, please consult ABB for eventual new rating data
and test reports at the required ambient temperature.
The ambient temperature must not be less than -20°C.
If lower temperatures are expected, please consult ABB.

Handling

2.1 Reception check

Immediately upon receipt check the motor for external
damage (e.g. shaft-ends and fl anges and painted
surfaces) and if found, inform the forwarding agent
without delay.
Check all rating plate data, especially voltage, winding
connection (star or delta), category, type of protection
and temperature class. The type of bearing is specifi ed
on the rating plate of all motors except the smallest
frame sizes.
In case of a variable speed drive application check the
maximum loadability allowed according to frequency
stamped on the motor's second rating plate.

2.2 Transportation and storage

The motor should always be stored indoors (above –
20°C), in dry, vibration free and dust free conditions.
During transportation, shocks, falls and humidity should
be avoided. In other conditions, please contact ABB.
Unprotected machined surfaces (shaft-ends and fl ang-
es) should be treated against corrosion.
It is recommended that shafts are rotated periodically
by hand to prevent grease migration.
Anti-condensation heaters, if fi tted, are recommended
to avoid water condensing in the motor.
The motor must not be subject to any external vibra-
tions exceeding 0.5 mm/s at standstill so as to avoid
causing damage to the bearings.
Motors fi tted with cylindrical-roller and/or angular
contact bearings must be fi tted with locking devices
during transport.

2.3 Lifting

All ABB motors above 25 kg are equipped with lifting
lugs or eyebolts.
Only the main lifting lugs or eyebolts of the motor
should be used for lifting the motor. They must not be
used to lift the motor when it is attached to other equip-
ment.
Lifting lugs for auxiliaries (e.g. brakes, separate cooling
fans) or terminal boxes must not be used for lifting the
motor.
Motors with the same frame may have a different center
of gravity because of different output, mounting ar-
rangements and auxiliary equipment.
Damaged lifting lugs must not be used. Check that
eyebolts or integrated lifting lugs are undamaged before
lifting.
Lifting eyebolts must be tightened before lifting. If
needed, the position of the eyebolt can be adjusted
using suitable washers as spacers.
