maintenance procedures until you understand the Warning and Caution statements.
A Warning statement indicates a possible unsafe condition that can cause harm to personnel.
A Caution statement indicates a condition that can cause damage to equipment.
Important:
This instruction manual is not intended to include a comprehensive listing of all details for all procedures required
for installation, operation and maintenance. This manual describes general guidelines that apply to most of the
motor products shipped by Baldor. If you have a question about a procedure or are uncertain about any detail,
Do Not Proceed. Please contact your Baldor District Office for more information or clarification.
Before you install, operate or perform maintenance, become familiar with the following:
• NEMA Publication MG-2, Safety Standard for Construction and guide for Selection, Installation and
Use of Electric Motors and Generators.
• The National Electrical Code
• Local codes and Practices
Safety Notice:
This equipment contains high voltage! Electrical shock can cause serious or fatal injury. Only qualified personnel
should attempt installation, operation and maintenance of electrical equipment.
Be sure that you are completely familiar with NEMA publication MG-2, safety standards for construction and
guide for selection, installation and use of electric motors and generators, the National Electrical Code and local
codes and practices. Unsafe installation or use can cause conditions that lead to serious or fatal injury. Only
qualified personnel should attempt the installation, operation and maintenance of this 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 disassembling 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.
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:
Guards must be installed for rotating parts to prevent accidental contact by personnel. Accidental contact
with body parts or clothing can cause serious or fatal 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:
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.
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:
Adjustable speed controls may apply hazardous voltages to the motor leads after power to the controller
has been turned off. Verify the controller is incapable of delivering hazardous voltages and that the voltage
at the motor leads is zero before proceeding. Failure to observe this precaution may result is severe bodily
injury or death.
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.
