Functional Design
AC and DC supply paths
ABB describes AC and DC inputs that are decoupled before the step-up converter, supporting a redundant supply concept.
Input status supervision
The AC and DC input voltages are monitored. AC and DC presence is shown by the AC ON and DC ON LEDs.
240 VDC continuity option
During brief DC supply interruptions, the 240 VDC output can be supported by an external capacitor connected at the specified output terminals.
24 VDC contact supply
The contact interrogation voltage is galvanically isolated, current-limited and short-circuit-proof according to the ABB description.
Lifecycle-Aware Verification
Record the complete order number, module designation and V2 marking from the nameplate.
Confirm AC/DC source ranges, output circuits, terminal assignments and cabinet protection.
Follow ABB hardware documentation and use qualified personnel for de-energized inspection and installation.
