High voltage and rotating parts can
cause serious or fatal in
Installation, operation and mainte-
nance of electric machinery should be
• Avoid extended exposure in close proximity
with high noise levels.
• Use proper care and procedures in handling,
lifting, installing, operating and maintaining
Familiarization with NEMA Publication MG-2,
Safety Standard for Construction and Guide
for Selection, Installation and Use of Electric
Motors and Generators, the National Electrical
Code and sound local practices is
recommended.
For equipment covered by this instruction
book, it is important to observe precautions to
protect personnel from possible injury. Among
the many considerations, personnel should be
instructed to:
• Avoid contact with energized circuits or
rotating parts.
• Avoid bypassing or rendering inoperative
any safeguards or protection devices.
• Avoid use of automatic-reset thermal
protection where unexpected starting of
equipment might be hazardous to
personnel.
• Avoid contact with capacitors until safe
discharge procedures have been followed.
• Be sure the shaft key is fully captive before
the motor is energized.
the equipment.
• The motor should be lifted by the lugs
provided. Do not lift anything but the motor
with the motor lifting means.
Safe maintenance practices by qualified
personnel are imperative. Before starting
maintenance procedures, be positive that:
• Equipment connected to the shaft will not
cause mechanical rotation.
• Main machine windings and all accessory
devices associated with the work area are
disconnected from electrical power sources.
If a high potential insulation test is required,
procedures and precautions outlined in NEMA
Standard MG-1 and MG-2 should be followed.
Failure to properly ground the frame of this
machine can cause serious injury to personnel
or death. Grounding should be in accordance
with the National Electrical Code and consistent
with sound local practice.
These instructions do not purport to cover all of the details or variations in equipment nor to provide for every possible
contingency to be met in connection with installation, operation, or maintenance. Should further information be desired or
should particular problems arise which are not covered sufficiently for the purchaser's purposes, the matter should be
referred to the General Electric Company.
