Unless otherwise stated, spare parts must be original
parts or approved by ABB.
Requirements in standard IEC/EN 60079-19 must be
followed.
When ordering spare parts, the motor's serial number, full
type designation and product code, as stated on the
rating plate, must be specified.
8.2 Dismantling, re-assembly
and rewinding
Follow the instructions given in standard IEC/EN 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 author-
ized repair partner.

8.3 Bearings

These must be removed using pullers and fitted by heating
or using special tools.
Bearing replacement is described in detail in a separate
instruction leaflet available from the ABB Sales Office.

be followed. The bearing types indicated on the rating
plate must not be changed.
