| PROTECTION |
Automatic Restart |
| Note: In a situation where the fan is locked by an external |
| force while the electricity is on, an increase in coil |
| temperature will be prevented by temporarily turning off |
| the electrical power to the motor. The fan will |
| automatically restart when the locked rotor condition is |
| released. |
| Polarity Protection |
