Safety Notice

  Continued

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:

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.

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 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 from the motor shaft before moving 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.
