Page 7: Acceptance Inspection
. ACCEPTANCE INSPECTION Check the following points after the motor has been delivered and before installing it. Before opening the package, confirm the orientation. If the package is crated, take care for the nails when unpacking. a. Check the type (TYPE), output (kW), poles (POLE), voltage (V) and frequency (Hz) indicated on the nameplate. b. -
Page 8: Shaft Protection Clamp
. SHAFT PROTECTION CLAMP A motor that uses roller bearings is equipped with the shaft protection clamp so that the shaft displacement or vibration during the transport would not damage the roller bearings. (Refer to Fig. 1.) Before hooking up the motor to a machine, loosen the installation bolt to remove the installation hardware. -
Page 9: Coupling With Machine
. COUPLING WITH MACHINE (1) Direct coupling (Refer to Fig. 2.) Install the motor so that the center of the motor-shaft and the center of the partner machine's shaft are aligned. Place a linear under the motor or machine leg if necessary, and completely adjust. Table 1 Allowable mounting dimensions of coupling Kind of Dimension A... - Page 10 (b) Obtain the center of t, apply a perpendicular load to the V-belt at this center point, and obtain the deflection force Td (N) where the deflection amount δ at that point is the following value. δ = 0.016 × t (mm) (Refer to Fig. 4.) For example, the deflection amount for a distance of 1m between the belt contact would be 0.016 ×1000 = 16 (mm).

(4) Chain drive Adjust the chain length so that a slight slackness is formed when the gears are aligned. The shaft-to-shaft distance should be larger than the diameter of the larger gears plus the diameter of the smaller gears. Consult with the chain manufacturer for the max. - Page 12 (2) Use an arm-type pulley that has a ventilation hole so that the pulley does not obstruct the ventilation cooling. Provide as large a ventilation hole as possible if a flat plate type is to be used. (Refer to Fig. 5.) (3) The V-Belt speed is as follows.

Page 13: Wiring
. WIRING (1) Wiring procedures Wiring work must be done according to the Electrical Equipment Technical Standards and Interior Wiring Code by a trained worker using suitable wiring tools. Working with live wires is dangerous. Always turn the power OFF before starting the work. The outline of the wiring requirements is shown in Table 5. If the wiring distance is long, the voltage drop will increase. - Page 14 (3) Switch and fuse Select the switch fuse according to the local power company's standards. Refer to Table 5 for the capacity and wire size of the switch, fuse and instruments. Use of the Mitsubishi MS magnetic switch for starting the motor and as overload protection is recommended.

Page 15: Initial Starting
(6) Protection device This motor does not have a protection device. Installation of an overload protection device is mandatory under the Electrical Equipment Technical Standards. Installation of a protection device (leakage breaker, etc.) besides an overload protection device is recommended. If switching surge may be caused by operating a circuit breaker, switch or magnetic valve, install a protection device for limiting surge. -

Page 17: Maintenance
. MAINTENANCE The quality of maintenance will greatly affect the motor life. (1) Inspection and maintenance schedule a. Motors used periodically, such as emergency motors absorb moisture as the stop time is long. This causes the insulation resistance to drop. Thus, daily caution is important. b. -
Page 18: Servicing Of Coils And Insulation
. SERVICING OF COILS AND INSULATION (1) When coil has absorbed moisture Measure the insulation resistance with a megger tester when the coil has absorbed moisture during shipment, storage or when the motor has been stopped for a long time, and at the times specified in the maintenance plan. If this measurement value drops suddenly, dry the coil. - Page 19 (2) Method of grease lubrication (replenishment) The motors with open bearings and a grease over-stuffing prevention structure are of either of the two configurations below. Lubricate the motor of each configuration according to the procedures below. In each event, when removing the old grease and charging the new, use care so as not to come into contact with the rotating bodies such as the shaft.

- Page 21 (6) Bearing noise The easiest way to check a bearing is to listen to the noise it generates. Listen to the bearing noise during operation so that abnormalities can be found at an early stage. However, do not rely on the noise only to decide pass or fail. Check the vibration, temperature and discharged grease so that you do not judge the practically all right parts to be defective.
- Page 22 (7) Bearing clearance When purchasing bearings from a bearing manufacturer, order the type with the bearing No. noted on the motor nameplate. Observe the following points when placing the order. a. Clarification of clearance symbol The bearing clearance is very important for the bearing life, noise and vibration. Thus, when purchasing the bearings, the clearance symbol must be clearly instructed in addition to the basic bearing No.

b. Installation of open type ball bearings or roller bearings (a) Put the bearing into a clean oil bath and heat it up to about 90°C for 30 minutes. Make absolutely sure that the temperature does not by all means exceed 100°C. Put the heated bearing on the shaft. Do not move the bearing until it has completely cooled down. - Page 26 Phenomenon Cause Remedy 1. The motor can be 1. The connection is incorrect. 1.
