VII. FAILURE
WARNING: An extreme overload or
electrical failure may result in
heating or arcing which can cause
the insulation to give off noxious fumes. All power
should be removed from the motor circuit as a
precaution even though the circuit has overload
protection.
Personnel should not approach the
motor until adequate ventilation of the area has
purged the air of fumes. When covers of a motor
are removed after a failure, care should be
observed to avoid breathing fumes from inside the
motor. Preferably, time should be allowed for the
motor to cool before attempting any examination
or repair.
WARNING:
applied to any electrically energized
equipment because electric shock
could result in serious or fatal injury. In case of fire,
disconnect all power and use a carbon dioxide
extinguisher to quench the flame. Before operating
any motor after a suspected failure, it should be
inspected for damage.
VIII. REPAIR
If a motor is marked with IECEx or ATEX designation
and repairs are required, the motor must be repaired
by operators trained in the understanding of BS/EN
60079-1 and BS/EN 60079-15 standards. The motor
has been designed to meet the rigid requirements of
these standards. Repair or alteration of the motor may

result in the motor no longer meeting the requirements
of these standards. If major repairs are undertaken
(such as rewinding a stator), proper facilities should be
made available and suitable precautions observed.
Recommended tightening torques for various parts is
listed in Tables 4A and 5B below.
WARNING:
insulation
welding near insulation during
rewinding, adequate ventilation must be provided
to avoid exposing personnel to noxious fumes.
Combustion of exhaust must be complete and
adequately vented to the outside atmosphere in
compliance with acceptable standards.
Exposure of personnel to air-borne inorganic fibers
must be avoided by adequate ventilation or by
wetting the remaining insulation components
following the burning of the organic materials.

RENEWAL PARTS
The use of only GE Energy renewal parts is
recommended.
When ordering, specify the model
number and the serial number of motor (complete
nameplate data is desirable).
