6. How to install motor and gearhead

Motor with Electromagnetic Brake Maintenance ManualT he gear head and motor should be handled, installed and maintained by trained technicians. Carefully read this manual and allaccompanying documents before use.
A copy of this manual should be sent to the actual user of the gear unit.
This manual should be maintained by the user.

1. Safety and other precautions• Install motor and gearhead, putting both contact surfaces together like fig.2 while rotating them little by little. Forcing into motor shaft andbumping into the inside of gearhead, at assembly, may cause abnormal noise by broken gearand shorten the operating life.
• When holding down transfer systems, such as chain, pulley, and sprocket, to the gearhead shaft with keyway, process keyway in the system side as
well and hold them down by attached key.

MotorWiring• Connect a power cable to the motor according to the connection diagram or maintenancemanual; otherwise, electric shock or fire may result.(Without terminal box, exercise insulation inthe connecting part.)• Do not forcibly curve, pull or clamp the power cable and lead wires; otherwise, electric shock mayresult.
• Correctly ground the grounding bolt; otherwise, electric shock may result.
• Use power source stated in the nameplate; otherwise, motor's burning or fire may result.
Operation• N ever approach or touch any rotating parts (shaft, etc.) during operation; otherwise, loose
clothing caught in these rotation parts may result in severe injury.
• W hen the power supply is interrupted, be sure to turn off the power switch. Unexpectedresumption of power may cause injury or damage to the equipment.
Daily inspection and maintenance• Never approach or touch any rotating parts (shaft, etc.) during maintenance ; otherwise, loose
clothing caught in these rotating parts may result in severe injury.
Inspection upon delivery• Verify that the unit received is in fact the one ordered. When a different product is installed, injury
or damage to the system may result.

General• The gear head and motor should be operated only within its name plate and catalogue ; otherwise, electric
shock, injury or damage to a system may occur.
• Keep hands and all foreign objects from the internal moving part of the gear unit and motor; otherwise,electric shock, injury, fire or damage to a system may occur.
• Damaged units should be taken off-line; otherwise, injury or fire may occur.
• Do not remove the nameplate.
•A ny modifications or alterations of any kind, to the unit, will void the warranty and all subsequent claims.
Transport• E xercise ample care not to drop the unit and fall during transport.
Installation• Do not place any inflammables around the gear head and motor; otherwise, fire may result.
• Do not place any objects that will hinder ventilation around motor; otherwise, cooling effect is reduced, andmay lead to a possible fire hazard and a burn due to excessive heat built-up.
• Do not touch the key way at the shaft end or on the inside of the dear unit and motor; otherwise, injury mayresult.
• When the unit is used in food processing applications vulnerable to oil contamination, install an oil pan orother such device to cope with rare oil leaking. Otherwise, oil leakage may damage products.
Coupling with other machines• Install appropriate guard devices around rotation parts ; otherwise, injury may result.
• Confirm the direction of rotation before coupling the unit with its driven machine. Difference in the directionof rotation may cause injury or damage to the system.
Wiring• Do not touch lead wire when measuring the insulation resistance. Electric shock may result.

4. Overheat protection device
1) Thermal protector type• When motor is run with overload or is stopped and overheated, in order to protector motor coil, overheat protection device, TP (Thermal protector ), is built in the coil.
• This TP has an automatic reset system.
So, if temperature in the coil returns to the normal level, this motor runs automatically.
2) Impedance protector type• Impedance protector motor is designed to enlarge impedance of coil winding, reduce the input current at motor restriction, and not to exceed the allowable max.temperature.
• ”ZP” as impedance protector is displayed in the nameplate.

5. Rating• Motor is designed to be suited to the usage conditions , and its usage limitation to fit to the usage conditions is called rating.
• There are some ratings, like continuous, short-time, and repetition rating. SHI’s induction motor is continuous rating and reversible motor is short-time rating (30min.).
