ELECTRICAL INSTALLATION
GROUNDING THE MOTOR
Ground the motor according to CE and local codes.
Consult the Canadian Electrical Code (CE) for information on grounding of
motors and generators and general information on grounding. In making the
ground connection, the installer should make certain that there is a solid and
permanent metallic connection between the ground point, the motor or
generator terminal housing and the motor or generator frame.
WIRING YOUR MOTOR
WARNING! Do not touch electrical connections unless you first ensure that
power has been disconnected. Please refer to: OSHA standard 1910.147
titled: The Control of Hazardous energy (lockout/tag-out).
WARNING! Surface temperatures of motor enclosures may reach
temperatures that can cause discomfort or injury to personnel coming in
contact with hot surfaces. 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.
Connect the motor as shown in the connection diagram
on the motor nameplate. Be sure to identify the proper
wiring diagram for the motor you are installing. If you
have difficulty determining the proper wiring diagram for
your motor, please contact Princess Auto for assistance.
If this motor is installed as part of a motor control drive
system, connect and protect the motor according to the
control manufacturer’s diagram. When using AC motors with frequency inverters, be
certain that the motors maximum speed rating is not exceeded. The wiring, fusing
and grounding must comply with the Canadian Electrical Code (CE) or International
Electrotechnical Commission (IEC) and local codes.
If improper rotation direction is detrimental to the load, check the rotation or ‘bump’
the motor prior to coupling the load to the motor shaft. When the motor is coupled to
the load and started, it should start quickly and run smoothly. If not, stop the motor
immediately and determine the cause. Possible causes are: low voltage at the motor,
motor connections are not correct or the load is too heavy. Check the motor current
