WARNING:
Do not touch electrical connections before you first ensure that power has been disconnected.
Electrical shock can cause serious or fatal injury. Only qualified personnel should attempt the
installation, operation and maintenance of this equipment.
WARNING:
Be sure the system is properly grounded before applying power. Do not apply AC power before
you ensure that all grounding instructions have been followed. Electrical shock can cause serious
or fatal injury. National Electrical Code and Local codes must be carefully followed.
WARNING:
Avoid extended exposure to machinery with high noise levels. Be sure to wear ear protective
devices to reduce harmful effects to your hearing.
WARNING:
This equipment may be connected to other machinery that has rotating parts or parts that are
driven by this equipment. Improper use can cause serious or fatal injury. Only qualified
personnel should attempt to install operate or maintain this equipment.
WARNING:
Do not by-pass or disable protective devices or safety guards. Safety features are designed to
prevent damage to personnel or equipment. These devices can only protection if they remain
operative.
WARNING:
Avoid the use of automatic reset devices if the automatic restarting of equipment can be
hazardous to personnel or equipment.
WARNING:
Be sure the load is properly coupled to the motor shaft before applying power. The shaft key
must be fully captive by the load device. Improper coupling can cause harm to personnel or
equipment if the load decouples from the shaft during operation.
WARNING:
Use proper care and procedures that are safe during handling, lifting, installing, operating and
maintaining operations.
Improper methods may cause muscle strain or other harm.
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:
Disconnect all electrical power from the motor windings and accessory devices before
disassembly of the motor. Electrical shock can cause serious or fatal injury.
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:
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:
This equipment is at line voltage when AC power is connected. Disconnect and lockout all
ungrounded conductors of the ac power line before proceeding. Failure to observe these
precautions could result in severe bodily injury or loss of life.
WARNING:
Rotating parts can cause serious or fatal injury. If relubrication is performed with the motor
running, to avoid injury do not contact any rotating parts.
WARNING:
Solvents can be toxic and/or flammable. Follow manufacturer’s safety procedures and
directions. Failure to observe this precaution could result in bodily injury.
