WARNING: The holding brake alone does not guaranty personnel safety. Use
structural measures such as protective fences or a second brake to
secure personnel safety.
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: 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: Ensure all electrical connections are securely made. High voltage may
be present and high motor speeds may result from a broken connection.
WARNING: Pacemaker Danger − Magnetic and electromagnetic fields in the vicinity
of current carrying conductors and permanent magnet motors can result
in a serious health hazard to persons with cardiac pacemakers, metal
implants and hearing aids.
WARNING: Dangerous movements can occur when a motor is improperly
connected or a fault occurs. Be careful during start−up, troubleshooting
and maintenance procedures to avoid injury.
WARNING: Severe burn is possible. The motor winding can reach 155 degrees C
during operation. Do not touch motor without protective clothing or
allow sufficient time for motor to cool to avoid burns.
