Auxiliary power supply configurations

5k A UM
The drive needs auxiliary power for:
■ the cooling system and a short-time power demand for the charging
unit of the drive.
■ the control hardware.
One single-phase power supply or two single-phase power supplies
feed the power to the drive.
The drive can be equipped with the following power supply options:
■ Standard power supply
The auxiliary power for the cooling system and the charging unit is
supplied to the drive by a three-phase AC power supply.
The auxiliary power for the control hardware is supplied by an
uninterruptible power supply (UPS) to a separate single-phase AC
input.
■ Optional power supplies
The total auxiliary power is supplied to the drive by a three-phase AC
power supply. If the power supply is interrupted, drive internal
capacitors provide a backup for the control hardware between 0.5
and 3 sec. The backup enables the drive to ride-through or to perform
a controlled shutdown.
In addition to the above power supplies, a separate power supply is
needed for
■ optional cabinet space heaters (110 / 230 V (AC)),
■ the excitation unit (option),
■ the synchronizing bypass unit (option).
For information on the configuration of the auxiliary power interface
present in the drive, see
For information on the rated voltage(s) and current(s), see
the drive.
