Modine Manufacturing ECO Technical Manual page 30

ENGLISH
8.3. Power supply 230V 50 Hz – EC motor
8.4. Before using speed adjustment systems, check their compatibility with the fan motors. Incompatible systems
can generate noise and damage. The Manufacturer assumes no responsibility for the performance of models
equipped with adjustment systems.
8.5. For other connections refer to the diagram printed on the inside of the motor-fan box.
8.6. In fan motors equipped with thermocontacts (TK), they must be connected to the control circuit.
8.7. In the models supplied with the wiring in the junction box, remove the side cover to make the connection.
