Safety Notice Continued
WARNING: UL Listed motors must only be serviced by UL Approved Authorized Baldor Service Centers if
these motors are to be returned to a hazardous and/or explosive atmosphere.
WARNING: Pacemaker danger − Magnetic and electromagnetic fields in the vicinity of current carrying
carrying conductors and permanent magnet motors can result result in a serious health hazard to
persons with cardiac pacemakers, metal implants, and hearing aids. To avoid risk, stay way from
the area surrounding a permanent magnet motor.
WARNING: Before performing any motor maintenance procedure, be sure that the equipment connected to
the motor shaft cannot cause shaft rotation. If the load can cause shaft rotation, disconnect the
load from the motor shaft before maintenance is performed. Unexpected mechanical rotation of
the motor parts can cause injury or motor damage.
WARNING: Use only UL/CSA listed explosion proof motors in the presence of flammable or combustible
vapors or dust.
WARNING: Motors that are to be used in flammable and/or explosive atmospheres must display the UL label
on the nameplate along with CSA listed logo. Specific service conditions for these motors are
defined in NFPA 70 (NEC) Article 500.
WARNING: Guards must be installed for rotating parts such as couplings, pulleys, external fans, and unused
shaft extensions, should be permanently guarded to prevent accidental contact by personnel.
Accidental contact with body parts or clothing can cause serious or fatal injury.
Caution: To prevent premature equipment failure or damage, only qualified maintenance personnel should
perform maintenance.
Caution: Do not over−lubricate motor as this may cause premature bearing failure.
Caution: Do not over tension belts. Excess tension may damage the motor or driven equipment.
Caution: Do not lift the motor and its driven load by the motor lifting hardware. The motor lifting hardware
is adequate for lifting only the motor. Disconnect the load (gears, pumps, compressors, or other
driven equipment) from the motor shaft before lifting the motor.
Caution: If eye bolts are used for lifting a motor, be sure they are securely tightened. The lifting direction
should not exceed a 20° angle from the shank of the eye bolt or lifting lug. Excessive lifting
angles can cause damage.
Caution: To prevent equipment damage, be sure that the electrical service is not capable of delivering more
than the maximum motor rated amps listed on the rating plate.
Caution: If a HI POT test (High Potential Insulation test) must be performed, follow the precautions and
procedure in NEMA MG1 and MG2 standards to avoid equipment damage.
If you have any questions or are uncertain about any statement or procedure, or if you require additional
information please contact your Baldor distributor or an Authorized Baldor Service Center.
Receiving
Each Baldor Electric Motor is thoroughly tested at the factory and carefully packaged for shipment. When
you receive your motor, there are several things you should do immediately.
1. Observe the condition of the shipping container and report any damage immediately to the
commercial carrier that delivered your motor.
2. Verify that the part number of the motor you received is the same as the part number listed on your
purchase order.
Handling
The motor should be lifted using the lifting lugs or eye bolts provided.
Caution: Do not lift the motor and its driven load by the motor lifting hardware. The motor lifting hardware
is adequate for lifting only the motor. Disconnect the load (gears, pumps, compressors, or other
driven equipment) from the motor shaft before lifting the motor.
1. Use the lugs or eye bolts provided to lift the motor. Never attempt to lift the motor and additional
equipment connected to the motor by this method. The lugs or eye bolts provided are designed to lift
only the motor. Never lift the motor by the motor shaft or the hood of a WPII motor.
2. To avoid condensation inside the motor, do not unpack until the motor has reached room temperature.
(Room temperature is the temperature of the room in which it will be installed).
The packing provides insulation from temperature changes during transportation.
3. When lifting a WPII (Weather Proof Type 2) motor, do not lift the motor by inserting lifting lugs into
holes on top of the cooling hood. These lugs are to be used for hood removal only.
A spreader bar should be used to lift the motor by the cast lifting lugs located on the motor frame.
