Auxiliary Power Connection of the Power Unit
The service 24 V DC supply terminal X80 for the power unit is used for service purposes together with the output terminal X67. When
there is a 24 V DC power, it is possible to update the firmware, do commissioning checks, or check node communication.
For service and commissioning procedures, connect 24 V DC supply to both terminals X80 and X67. After the tasks are completed,
disconnect the 24 V DC supply.

During normal operation, the 24 V DC output terminal X67 provides power supply and AuxBus connectivity for the system module. The
power supply is a GND referenced, +24 V DC ±5%, 40 W supply which is also used for powering the AuxBus. The AuxBus topology and
connection points are described in 6.16.2 AuxBus Cable Requirements. The power supply is recommended and designed for powering
the control unit and options of the system module.
The recommended connector is 1769919/Phoenix contact. The correct tightening torque is 0.22–0.25 Nm (1.9–2.2 in-lb).
