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 re-
moved 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 totally
enclosed
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 ex-
amination or repair.
Water should not be 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. Remove covers and make visual inspections of the brushes, commutator, connections
and windings. Electrical tests of each winding to check for open or short circuit or grounds
should be made. Any arc damage should be cleaned up and repaired as necessary. Brushes
may need reseating before operation.
VI. RENEWAL PARTS
Using genuine GE renewal parts assures continued high performance and the full benefits of the long operating life
designed into your GE motor.
Downtime can be minimized by having a protective stock of parts available for replacement. (Refer to Table 14.)
The permanently attached nameplate on your GE motor displays the model and serial number, providing all the
information needed for ordering. Parts are available directly from authorized GE Industrial Systems parts dis-
tributors. Direct electronic access to the factory database of motor information and warehouse inventories enables
distributors to quickly identify part numbers, delivery times and order status.
A. Storage of Renewal Parts
Store supply parts in a clean, dry, ventilated place, protected from rodents and termites, to prevent damage or
loss. Slush all finished iron or steel surfaces with heavy oil or compound to protect them from corrosion.
The parts should be inspected occasionally to ensure their continuous usability.
