4. 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 frequency
±2% according to EN / IEC 60034-1 (2004), paragraph
7.3, Zone A.
The motor can only be used in applications it is intended
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 construction
data must be checked. Please contact ABB for further
information.
Particular attention must be paid to corrosive atmospheres
when using flameproof motors; ensure that the paint
protection is suitable for the ambient conditions as corro-
sion 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 sufficient airflow. Ensure that no
nearby objects or direct sunshine radiate additional heat to
the motor.
For flange mounted motors (e.g. B5, B35, V1), make sure
that the construction allows sufficient air flow on the outer
surface of the flange.

4.3 Safety considerations

The motor is intended for installation and use by qualified
personnel, familiar with 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
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 espe-
cially after shut-down.
3. Some special motor applications require special instruc-
tions (e.g. using frequency converter supplies).
4. Be aware of rotating parts of the motor.
5. Do not open terminal boxes while energized.
