￭ Fieldbus control
You can control the unit through a fieldbus interface if the unit is equipped with an optional
fieldbus adapter (for example, K454), and when you have configured the control
program for the fieldbus control with the parameters. For information on the parameters,
see the firmware manual.
Note: To be able to switch the main breaker [Q1] and the supply unit on and off (Run enable
signal) through the fieldbus, the Run enable command at digital input DI2 must be on (1).
That is the case when the operating switch [S21] is switched to the ENABLE/RUN position.
