•
When using a chain, attach so that the chain tension angle is perpendicular to the shaft.
•
Refer to the chain catalog or other reference for chain tension.
•
Select a sprocket or gear pitch diameter that is at least three times the shaft diameter.
•
The working load point of the sprocket or gear should go as close to the product as possible (See Figure 5-2).
It is recommended that the load point does not go beyond the center of the shaft’s length.
•
Over-tightening the V belt will damage the shaft and bearing. Refer to the V belt catalog or other reference for
V belt tension.
•
The parallelism, eccentricity β of the two pulleys should be within 20´. (See Figure 5-3)
•
When using multiple V belts, use a matched set having the same length.

•
For brakemotors, install the rectier where the temperature is less than 140°F (60°C).
•
Long wires cause the voltage to drop. Select cables with appropriate diameter so that the voltage
drop will be less than 2%.
•
After wiring the motor, check that the terminal box mounting bolts are tight.

This section details wiring for standard Sumitomo three-phase motors and brakemotors. If using a motor
manufactured by a company other than Sumitomo, please refer to that manufacturer’s instruction manual for wiring,
operating and maintenance details. When wiring motors into the power supply, Sumitomo recommends the use of
terminal rings to facilitate the connection:
6. Motor Wiring
•
Do not handle the unit when cables are live. Be sure to turn-o the power; otherwise electric shock
may result.
•
Connect the power cables to the unit according to the connection diagram shown inside the
terminal box or in the maintenance manual; otherwise electric shock or re may result.
•
Correctly ground the grounding bolt; otherwise electric shock may result.
•
Keep all wiring and electrical parts dry and moisture free.
•
Follow local electrical codes and regulations when wiring; otherwise burning, electrical shock, injury
and/or re may result.
•
The motor is not equipped with an overload device. Sumitomo strongly recommends that another
protective device (i.e.: ground fault interrupters, etc.), in addition to an overload device, be installed
in order to prevent burning, electric shock, personal injury and/or re.
•
For single phase motors, exercise caution so as to not damage the vinyl cover of the starting
capacitor, otherwise shock may result.
•
For brakemotors, do not electrify a brake coil continuously when the motor is stopped otherwise
the brake coil may burn and re may result.
