Figure 6 Stepper Motor 4Nm and 8Nm assembly schematic 3.2 Connection and wiring To perform the correct setup, please refer to the following diagrams representing possible ways of motor connection. Installation and connection can be done by qualified personnel only. Failure in performing in any of this operations may result in risk of fatal injury, electric shock, incorrect mounting or product damage. - Page 8 Figure 7 Stepper motor with male type terminal Figure 8 Connection cable with dedicated terminal Due to length of the motor cables, extension cables connecting motor with the controller are supplied additionally. Extension cable is equipped with 4 pole connectors sleeves fitting terminal of the motors (Figure 11). Lengths of the cables differs depending on the size of the Rotary Heat Exchanger.
