ENGLISHFRANÇAIS1. INTRODUCTIONBefore you install, operate or perform maintenance, become familiarwith the following: N EMA Publication MG-2: Safety Standard for Construction and Guide forSelection, Installation and Use of Electric Motors. IEC 60034-1 Electrical and IEC 60072-1 Mechanical specifications ANSI C51.5, the National Electrical Code (NEC) and local codes and practices. O SHA standard 1910.147 titled: The Control of Hazardous energy(lockout/tag-out).2. SAFETY NOTICEWARNING: All operations must be carried out byappropiately trained personnel. Electric motors haveenergized circuits and exposed rotating parts whichmay cause injuries to people.Only qualified personnel, trained in the safe installation and operation of thisequipment, should install this motor. When improperly installed or used, rotatingequipment can cause serious or fatal injury. Equipment must be installed inaccordance with the National Electrical Code (NEC), local codes and NEMA MG2Safety Standards for Construction and Guide for Selection, Installation and Useof Electric Motors and Generators and OSHA regulation standard 1910.147 titled:The control of hazardous energy (lockout/tag-out).Use correct material handling equipment to avoid injury. Use caution whenremoving the motor from its packaging. Sharp corners may exist on motor shaft,motor key, sheet metal and other surfaces.1. onnect Power and Ground to the motor according to NEC or IEC and localCcodes.2. rovide a permanent guard to prevent accidental contact of body parts orPclothing with rotating or moving parts of motor. Beware of burns if motor is hot.3.Shaft key must be secured before starting motor.4. ounting bolts should be high tensile steel. Be sure to use a suitable lockingMdevice on each bolt (spring washer or thread lock compound).5. o not apply power to the motor until the motor is securely mounted by itsDmounting holes.6. his motor must only be connected to the proper line voltage, line frequencyTand load size.3 Techtop MotorsTechtopCanada.com

ENGLISHFRANÇAIS7. otors are not to be used for load holding or restraining unless a properlyMsized brake is installed. If a motor mounted brake is installed, provide propersafeguards in case of brake failure.8. isconnect all power services, stop the motor and allow it to cool beforeDservicing.9. or single phase motors, discharge the start and/or run capacitors beforeFservicing.10. Do not by-pass or render any inoperative safety devices.3. RECEIVINGOnce you receive your motor, instantly observe the condition of the shippingcontainer. Immediately report any damage to the commercial carrier thatdelivered your motor.Verify that the part number of the motor you received is the same as the partnumber listed on your purchase order.4. HANDLINGUse correct material handling equipment to avoid injury. Use caution whenremoving the motor from its packaging. Sharp corners may exist on motor shaft,motor key, sheet metal and other surfaces.5. GUARDINGAfter motor installation is complete, a guard of suitable dimensions must beconstructed and installed around the motor. This guard must prevent personnelfrom 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 mountedbrake is installed, provide proper safeguards for personnel in case of brake failure.WARNING: Guards must be installed to form asafe and uncompromised perimeter around rotatingparts such as couplings, pulleys, external fans, andunused shaft extensions.All parts should be permanently guarded to prevent accidental contact bypersonnel. Accidental contact with body parts or clothing can cause seriousor fatal injury. When this motor is installed according to these instructions, itcomplies with the EEC Machinery Directive. Electromagnetic Compatibility(EMC) requirements for CE compliance are met when the incoming power ispurely sinusoidal.TechtopCanada.comTechtop Motors 4

ENGLISHFRANÇAIS6. MOUNTINGFOOT MOUNTED: Foot mounted motors should be mounted to a rigidfoundation to prevent excessive vibration. Shims may be used if thelocation is uneven. Improper alignment may void the motor’s warranty.FLANGE MOUNTED: Flange mounted motors should be properly seated andaligned. Note: If improper rotation direction is detrimental to the load, check therotation 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 overtighten belts as this may cause premature bearing failure or shaft breakage.DIRECT COUPLED: Direct coupled motors should be carefully alignedand the shaft should rotate freely without binding or drag.Note: Techtop Motors with frame 254T and larger are shipped with anopposite drive end bearing lock. If front end bearing locks are desired,please contact Techtop for assistance.7.

ENGLISHFRANÇAIS8. GROUNDINGGround the motor according to NEC and local codes. In the USA, consult theNational Electrical Code, Article 430 for information on grounding of motors andgenerators, and Article 250 for general information on grounding. In making theground connection, the installer should make certain that there is a solid andpermanent metallic connection between the ground point, the motor or generatorterminal housing, and the motor or generator frame. In non-USA locations consultthe appropriate national or local code applicable.9. WIRING YOUR MOTORConnect 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 youhave difficulty determining the proper wiring diagram for your motor, please contactTechtop for assistance. If this motor is installed as part of a motor control drivesystem, connect and protect the motor according to the control manufacturer’sdiagram. When using AC motors with frequency inverters, be certain that themotors maximum speed rating is not exceeded. The wiring, fusing and groundingmust comply with the National Electrical Code or IEC and local codes. Note: Ifimproper 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 coupledto the load and started, it should start quickly and run smoothly. If not, stop themotor immediately and determine the cause. Possible causes are: low voltage at themotor, motor connections are not correct or the load is too heavy. Check the motorcurrent after a few minutes of operation and compare the measured current with thenameplate rating.WARNING: Do not touch electrical connectionsunless you first ensure that power has beendisconnected.
