Operation

4.1 Use

The motors are designed for the following conditions
unless otherwise stated on the rating plate.
– Normal ambient temperature limits are -20°C to
+40°C.
– Maximum altitude 1000 m above sea level.
– Tolerance for supply voltage is ±5% and for frequen-
cy ±2% according to EN / IEC 60034-1 (2004),
paragraph 7.3, Zone A.
The motor can only be used in applications it is intend-
ed for. The rated nominal values and operational
conditions are shown on the motor rating plates. In
addition, all requirements of this manual and other
related instructions and standards must be followed.
If these limits are exceeded, motor data and construc-
tion data must be checked. Please contact ABB for
further information.
Particular attention must be paid to corrosive atmos-
pheres when using fl ameproof motors; ensure that the
paint protection is suitable for the ambient conditions as
corrosion can damage the explosion-proof enclosure.
WARNING
Ignoring any instructions or maintenance of the
apparatus may jeopardize safety and thus prevent
the use of the machine in hazardous areas.

4.2 Cooling

Check that the motor has suffi cient airfl ow. Ensure that
no nearby objects or direct sunshine radiate additional
heat to the motor.
For fl ange mounted motors (e.g. B5, B35, V1), make
sure that the construction allows suffi cient air fl ow on
the outer surface of the fl ange.

4.3 Safety considerations

The motor is intended for installation and use by quali-
fi ed personnel, familiar with health and safety require-
ments and national legislation.
Safety equipment necessary for the prevention of
accidents at the installation and operating site must be
provided in accordance with local regulations.
WARNING
Emergency stop controls must be equipped with
restart lockouts. After emergency stop a new start
command can take effect only after the restart
lockout has been intentionally reset.
Points to observe
1. Do not step on the motor.
2. The temperature of the outer casing of the motor may
be hot to the touch during normal operation and
especially after shut-down.
3. Some special motor applications require special
instructions (e.g. using frequency converter supplies).
4. Be aware of rotating parts of the motor.
5. Do not open terminal boxes while energized.
