4. Operation
4.1 Use
The motors are designed to be used in the following
conditions, unless otherwise stated on the rating plate.
– Normal ambient temperature limits are 0 °C to +40°C.
Derating of the electrical performance of the motor is
mandatory in the range of 40–50 °C.
– The maximum altitude is 1000 m above sea level.
The motor can only be used for applications for which it is
intended to be used. The rated nominal values are shown
on the motor rating plates. In addition, all the requirements
of this manual and any other related instructions and
standards must be followed.
If these limits are exceeded, the motor data and construc-
tion data must be checked. Please contact ABB for further
information.
WARNING
Motors equipped with a brake should not be run
before the brake is released by the correct voltage
supply. Not following this procedure will critically
damage the brake.
WARNING
Ignoring any of these instructions or neglecting the
maintenance of the apparatus may jeopardize the
safety of the machine, and thus prevent it from being
used.
4.2 Cooling
HDP series motors use a forced-air cooling system which
uses either axial servo-fans (IP54 version) or radial fans
(IP23 version).
The coolant is air, which is moved by a component mount-
ed on the motor, the power for which is obtained in such a
way that it is independent of the rotational speed of the
machine.
Make sure that the construction allows sufficient air flow
into and out of the motor at the designated inlet and outlet
points. For IP54 motors, allow a free space of at least
100 mm behind the motor air inlet.
WARNING
Do not use any coolant other than air.
4.3 Safety considerations
The machine is intended for installation and use by quali-
fied personnel who are familiar with the health and safety
requirements and national legislation.
Safety equipment necessary for the prevention of acci-
dents at the installation and operating site must be pro-
vided in accordance with local regulations.
WARNING
Do not carry out work on the motor, connection
cables or accessories such as frequency converters,
starters, brakes, thermistor cables or heating ele-
ments when voltage is applied.
Points to observe
1. Do not step on the motor.
2. The temperature of the outer casing stator surface of
the motor may be too hot to touch during normal
operation, and especially after shutdown.
3. Some special motor applications require special
instructions.
4. Be aware of the rotating parts of the motor.
5. Do not open terminal boxes while they are energized.
6. Low-voltage motors in variable-speed operation
