5. Operation

5.1 General

The motors are designed for the following conditions
unless otherwise stated on the rating plate:
− Motors are to be installed in fixed installations only.
− Normal ambient temperature range is from –20 °C to
+40 °C.
− Maximum altitude is 1000 m above sea level.
− The variation of the supply voltage and frequency may
not exceed the limits mentioned in relevant standards.
Tolerance for supply voltage is ±5 %, and for frequency
±2 % according to Figure 4 (EN / IEC 60034-1,
paragraph 7.3, Zone A). Both extreme values are not
supposed to occur at the same time.
The motor can only be used in applications for which it is
intended. 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 explosive atmospheres.
