Communication with the control, even when the line voltage is switched off
If, in your plant or system, communication with the control system should continue to function
even when the line voltage is switched off, then you must externally supply the
inverter/Control Unit with 24 V DC. To do this, use terminals 31 and 32 – or connector X01.
You can find additional details in the operating instructions for the inverter or the Control
Unit.
