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 prior to 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 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 after a few minutes of operation and compare the measured current with the nameplate rating.

Care & Maintenance

Maintain the tool with care. A tool in good condition is efficient, easier to control and will have fewer problems.
Inspect the tool components periodically. Repair or replace damaged or worn components. Only use identical replacement parts when servicing.
Maintain the tool's labels and name plates. These carry important information. If unreadable or missing, contact Princess Auto Ltd. for replacements.

WARNING! Only qualified service personnel should repair the tool. An improperly repaired tool may present a hazard to the user and/or others.

Lubrication

The bearings are permanently lubricated and do not require additional grease.

Disposal

Recycle a tool damaged beyond repair at the appropriate facility.

Troubleshooting

Visit a Princess Auto Ltd. location for a solution if the tool does not function properly or parts are missing. If unable to do so, have a qualified technician service the tool.

Problem(s)	Possible Cause(s)	Suggested Solution(s)
Motor will not start.	There is a blown fuse or open circuit breaker. Motor starter overload activated. The thermal switch is open. Low or no voltage reaching motor. Power enters control circuit but does not reach the motor.	Test for voltage at the fuse or circuit breaker. Also see if the voltage/amp rating of the fuse or circuit breaker is correct for the motor. It should exceed the Motor's FLC by 25 percent. The thermal protector will automatically reset and the motor will function normally again once it has cooled. Test the starter before starting motor again. The thermal protector will automatically reset and the motor will function normally again once it has cooled. Beware as the motor may automatically start when reset. Check each motor terminal's voltage. The voltage should be within 10% of the voltage on the motor's nameplate. Disconnect the load and apply power to the motor. If the motor operates normally, then the issue is with the load attached to the motor. Should the motor still not work, have it serviced or replaced by a qualified technician. Begin by confirming all contacts are clean and tight. Examine for obvious damage. Test each part of the circuit for power until the problem area is discovered. Have a qualified service technician repair or replace the circuit.
Fuse/circuit breaker overloads.	There is a blown fuse or open circuit breaker. Motor starter overload activated. Power enters control circuit but does not reach the motor. Low or no voltage reaching motor. Motor shaft does not turn when power applied.	Test for voltage at the fuse or circuit breaker. Also see if the voltage/amp rating of the fuse or circuit breaker is correct for the motor. It should exceed the Motor's FLC by 25 percent. The thermal protector will automatically reset and the motor will function normally again once it has cooled. Test the starter before starting motor again. Begin by confirming all contacts are clean and tight. Examine for obvious damage. Test each part of the circuit for power until the problem area is discovered. Have a qualified service technician repair or replace the circuit. Check each motor terminal's voltage. The voltage should be within 10% of the voltage on the motor's nameplate. Disconnect the load and apply power to the motor. If the motor operates normally, then the issue is with the load attached to the motor. Should the motor still not work, have it serviced or replaced by a qualified technician. Disconnect the motor from the load and test under no-load conditions. If the shaft does not turn, the bearing is immobilized. Have the motor serviced or replaced by a qualified technician.
Motor is overheating.	Broken or disconnected ground. Hot power lead is connecting to the motor frame. Motor overloads during operation. Starting windings remain active in circuit as motor accelerates. Worn or poorly lubricated bearings. Inadequate ventilation reaching the motor.	Reconnect or replace the ground wire and test for proper ground. Have a qualified technician inspect the motor and repair/replace the defective wiring. A moving part of the motor may be binding. Inspect the motor to see if any parts are touching. Check to see the motor's shaft is straight. Run the motor under normal load and check the amount of current it is drawing. Disconnect the motor from its load and check the current drawn while running under no-load. If the current draw is excessive under load, but normal when there is no-load, Inspect the load to determine the problem. If the no-load current is above the listed rating, have the motor serviced or replaced by a qualified technician. Switch motor off to listen for a click. This is the centrifugal switch closing as the motor slows. Damaged or poorly lubricated bearing can be heard. This may be a result of wear, inadequate oil reaching the bearings or the motor overheating. Contact Princess Auto Ltd. for a solution. Clean/clear all ventilation openings. Use dry compressed air if blowing debris out of the ventilation openings.
Excessive vibration or noise.	Excessive end play in motor. Worn or poorly lubricated bearings.	An unbalanced motor or load creates vibration. Check for excessive end play or loose parts. Realign the motor and load. Check end play by trying to move the motor shaft in and out. Add end-play washers as required. If the shaft is bent, replace the rotor or motor.
