3.5.2. Connection Diagrams
The various Drum HV (High Voltage) models connection diagrams differ from one another.
The following diagrams depict the two different possibilities for power supply connections:
• 400 V & 800 V S-models that feature power supply backup functionality, needing an Aux.
24 V backup supply (The drive will not be operative, without having the external 24 VDC
supply).
• 400 V model without power supply backup functionality (The drive’s internal DC/DC
converter is fed from the VP+ and VN- , of the internal drive's bus line).
