Asynchronous Motors Ver. 0002 AM - 23
AM.8.2 FEEDBACK CONNECTION. ENCODER
It is done through a 12-pin male Conney connector which assures a sealing degree of IP65.
The various available encoder models use this connector.
The cable required to connect this connector with drive module is the one referred to as EEC.
Chapter IN describes this cable in detail.

position.
AM.8.3 FAN CONNECTION
The fan is always supplied with 220Vac. On most motors, it is carried out through a terminal
box. Only SPM90 motors use a connector that is provided with the motor (maximum cable
section, 2.5 mm

).
A previous section describes the characteristics of the fans.
