• Electric Motor

ASSEMBLY & INSTALLATION MOUNTING

• Foot mounted: Foot-mounted motors should be mounted to a rigid foundation to prevent excessive vibration. Shims may be used if the location is uneven.
• Flange mounted: Flange-mounted motors should be properly seated and aligned. If improper rotation direction is detrimental to the load, check the rotation or ‘bump’ the motor before coupling the load to the motor shaft.
• V-belt drive: Mount the sheave pulley close to the motor housing. Allow clearance for end-to-end movement of the motor shaft. Do not over-tighten belts as this may cause premature bearing failure or shaft breakage.
• Direct coupled: Direct coupled motors should be carefully aligned and the shaft should rotate freely without binding or drag.

BUILD A GUARD
WARNING! Guards must be installed to form a safe and uncompromised perimeter around rotating parts such as couplings, pulleys, external fans, and unused shaft extensions.
After motor installation is complete, a guard of suitable dimensions must be constructed and installed around the motor. This guard must prevent personnel from coming in contact with any moving parts of the motor or drive assembly but must allow sufficient cooling air to pass over the motor. If a motor- mounted brake is installed, provide proper safeguards for personnel in case of brake failure.

All parts should be permanently guarded to prevent accidental contact by personnel. Accidental contact with body parts or clothing can cause serious or fatal injury. When this motor is installed according to these instructions, it complies with the EEC Machinery Directive. Electromagnetic Compatibility(EMC) requirements for CE compliance are met when the incoming power is purely sinusoidal.

ELECTRICAL INSTALLATION

GROUNDING THE MOTOR
Ground the motor according to CE and local codes. Consult the Canadian Electrical Code (CE) for information on the 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 motor’s 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 before 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 after a few minutes of operation and compare the measured current with the nameplate rating.
