The fan's operation when the PWM control lead wire is not connected (when the control terminal is open) varies depending on the model.
Please refer to the "San Ace Catalog" for the specifications of each model.
<Example>
* Note:
If the control lead wire is not connected, please take appropriate safety measures.
For example:
- Bundle the lead wires to prevent them from being caught in the rotating fan.
- Insulate the end of the control lead wire to prevent it from coming into contact with
other lead wires, power terminals, or other conductive parts.
