1-2 General Information MN408
Safety Notice Continued
WARNING: Do not use non UL/CSA listed explosion proof motors in the presence of flammable or combustible
vapors or dust. These motors are not designed for atmospheric conditions that require explosion proof
operation.
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 tension belts. Excess tension may damage the motor or driven equipment.
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 (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 º 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.
Caution: The space heaters are designed to operate at or below the maximum surface temperature stated on the
nameplate. If the marked ambient and/or voltage are exceeded this maximum surface temperature can
be exceeded and can damage the motor windings. If applied in a division 2 or zone 2 environment this
excessive temperature may cause ignition of hazardous materials.
Caution: Shaker Duty motors must be properly lubricated prior to Start Up to prevent damage. See Section 3.
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.
4. If the motor must be mounted to a plate with the driven equipment such as pump, compressor etc., it may
not be possible to lift the motor alone. For this case, the assembly should be lifted by a sling around the
mounting base. The entire assembly can be lifted as an assembly for installation. Do not lift the assembly
using the motor lugs or eye bolts provided. Lugs or eye bolts are designed to lift motor only. If the load is
unbalanced (as with couplings or additional attachments) additional slings or other means must be used
to prevent tipping. In any event, the load must be secure before lifting. If the load is unbalanced (as with
couplings or additional attachments) additional slings or other means must be used to prevent tipping. In
any event, the load must be secure before lifting.
