Motor-fan connection diagram
Important. The motors are equipped with inner thermal protection with automatic reconnection. Before using motor
speed control systems verify the compatibility with the motors. Non compatible systems may damage motors or
increase noise level; Modine will not be responsible for model performance with speed control systems. For fans
equipped with thermal contacts (TK), these must be connected to the control circuit. For models supplied with wiring
in a junction box, remove the cover to make the connection.
