equipment.
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: 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: 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: Surface temperatures of motor enclosures may reach temperatures which can cause discomfort or
injury to personnel accidentally coming into contact with hot surfaces. When installing, protection
should be provided by the user to protect against accidental contact with hot surfaces. Failure to
observe this precaution could result in bodily injury.
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 provide 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: 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: Thermostat contacts automatically reset when the motor has slightly cooled down. To prevent injury or
damage, the control circuit should be designed so that automatic starting of the motor is not possible
when the thermostat resets.
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: 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.
