1. Remove the right lateral panel unscrewing the four fixing screws and find the earth buckle [J2] ON THE
MOTOR'S BODY. If this is not easily accessible, remove the left lateral panel also;
Disconnect the connector of the motor's cable [J1], noting the contact's position, and disconnect the earth
buckle positioned on the motor's body [J2] unscrewing the screw.

direction shown in the figure.
When reassembling the motor, always remember to connect the earth buckle [J2], with the motor and check
that the contacts of the connector [J1] are correctly positioned.
