2.2.2 Auxiliary power supply configurations
The drive needs auxiliary power for:
• the cooling system and a short-time power
demand for the charging unit of the drive
The power is fed by a three-phase power sup-
ply.
• the control hardware
The power is fed by one single-phase power
supply.
The drive can be equipped with the following
power supply options:
• Standard power supply
The drive is equipped for one three-phase
power supply that provides the total auxiliary
power.
• Optional power supplies
To accommodate requirements for safe opera-
tion if the auxiliary power fails, the drive can be
furnished with one three-phase power supply
and one single-phase power supply.
Independent of the power supply scheme, the drive
provides an internal back-up supply for 100 ms.
This safety feature enables the control system to
shut down the drive in a controlled manner if the
auxiliary power fails.
Optionally the drive can be equipped with an addi-
tional battery. The battery supports 15 minutes
ride-through operation of the control system.
The power feed for the auxiliary supply
must be protected with a suitable circuit
protection rated for the inrush current.
For information, see utility consumption
list of the drive.
For information on the configuration of
the auxiliary power interface in the drive,
see Appendix D – Wiring diagrams.
