7.1 Spare parts

Spare parts must be original parts or approved by ABB
unless otherwise stated.
Requirements in standard IEC 60079-19 must be
followed.
When ordering spare parts, the motor serial number, full
type designation and product code, as stated on the
rating plate, must be specifi ed.
7.2 Dismantling, re-assembly
and rewinding
Follow the instructions given in standard IEC 60079-19
regarding dismantling, re-assembly and rewinding. Any
operation must be undertaken by the manufacturer, i.e.
ABB, or by an ABB authorized repair partner.
No manufacturing alterations are permitted on the parts
that make up the explosion-proof enclosure and the
parts that ensure dust-tight protection. Also ensure that
the ventilation is never obstructed.
Rewinding must always be carried out by an ABB
authorized repair partner.
When re-assembling the end shield or terminal box to
the frame of fl ameproof motors, check that the spigots
are free of paint and dirt with only a thin layer of special
non-hardening grease. In the case of DIP/Ex tD motors,
when re-assembling the end shields on the frame
special sealing grease or sealing compound must be
reapplied to the spigots. This should be the same type
as originally applied to the motor for this kind of protec-
tion.

7.3 Bearings

Special care should be taken with the bearings.
These must be removed using pullers and fi tted by
heating or using special tools for the purpose.
Bearing replacement is described in detail in a separate
instruction leafl et available from the ABB Sales Offi ce.
Special recommendations apply when changing the
bearings of DIP/Ex tD-motors (as the seals should be
changed at the same time).
Any directions placed on the motor, such as labels,
must be followed. The bearing types indicated on the
rating plate must not be changed.
NOTE!
Any repair by the end user, unless expressly ap-
proved by the manufacturer, releases the manufac-
turer from his responsibility to conformity.

requirements

8.1 Noise levels

Most of ABB's motors have a sound pressure level not
exceeding 82 dB(A) (± 3 dB) at 50 Hz.
Values for specifi c machines can be found in the
relevant product catalogs. At 60 Hz sinusoidal supply
the values are approximately 4 dB(A) higher compared
to 50 Hz values in the product catalogs.
For sound pressure levels at frequency converter
supply, please contact ABB.
