2.2 Power supply configuration
The drive requires two independent power supplies:
• Main power supply for the power electronic
components
• Auxiliary power supply for the control and cool-
ing equipment
2.2.1 Main power supply with input isolation
transformer
The main power is fed to the drive by the input iso-
lation transformer which adapts the line voltage to
the required voltage for the drive. The input isola-
tion transformer is always part of the drive system.
Two installation solutions are available for the
transformer:
• Integrated
The transformer is placed on the left side of the
drive. The length of the cabinet depends on
drive power. For the integrated configuration, a
dry-type transformer is used.
• Non-integrated
The transformer is external to the drive. The
transformer can either be an oil-immersed or
dry-type device. The distance between drive
and transformer is determined by the maximum
possible cable length for the transformer sec-
ondary cables.
Drives with an non-integrated transformer are
equipped with a common mode choke.
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.
