3.3.2. Auxiliary power supply configurations
The total auxiliary power demand of the drive includes:
–
Auxiliary power for the cooling system
– Auxiliary power for the control hardware and the gate units which are used to
trigger the power semiconductors
The total auxiliary power can be fed to the drive in the following ways:
–
Through a common power supply
•
The total auxiliary power is supplied to the drive by a three-phase AC power
supply.
• If the power supply is interrupted, drive internal batteries provide a backup
for the control system, thus enabling the drive to ride-through and/or to
perform a controlled shutdown.
– Through separate power supplies
•
The auxiliary power is supplied to the drive by a three-phase AC power
supply and by an UPS to a separate one-phase AC or DC input.
• Feeding the control power separately by an UPS has the advantage that the
main control hardware will remain energized, the full ride-through
capabilities of the drive can be used, and the communication to a higher-
level control system will not be lost in the event of an auxiliary power
outage.
IMPORTANT!
The power feed for the auxiliary supply must be protected with a
suitable circuit protection rated for the inrush current.

For more information on the auxiliary power interface of the drive, see
“Appendix D
- Wiring diagrams”.
– For information on the rated voltage(s) and current(s), see the rating plate of
the drive.
