1.5.1 Cyber Security Disclaimer
This product is designed to be connected to and to
communicate information and data via a network
interface.
It is Customer's sole responsibility to provide and
continuously ensure a secure connection between
the product and Customer network or any other
network (as the case may be). Customer shall
establish and maintain any appropriate measures
(such as but not limited to the installation of firewalls, application of authentication measures,
encryption of data, installation of anti-virus programs, etc) to protect the product, the network, its
system and the interface against any kind of security breaches, unauthorized access, interference,
intrusion, leakage and/or theft of data or information.
ABB and its affiliates are not liable for damages
and/or losses related to such security breaches,
any unauthorized access, interference, intrusion,
leakage and/or theft of data or information.
1.5.2 User Lock
For better cyber security, it is highly recommended
that you set a master pass code to prevent e.g. the
changing of parameter values.
To activate the user lock for the first time, enter
the default pass code, 358, into 16.02 Passcode.
This will make parameters 16.16…16.17 changeable. Then enter the old pass code to 16.16 OldUserPasscode and change user pass code in 16.17
NewUserPasscode. In 16.02 Parameter Lock, the
user lock functionality can now be enabled.
WARNING !!
ABB will not be liable for damages or losses caused
by the failure to activate the user lock using a new
pass code. See 1.5.1 Cyber Security Disclaimer.

The following sections provide an overview of:
• ACS2000 DFE (diode front end) and integrated
input transformer,
• available main and auxiliary power configura tions,
• major power electronic components of the
drive,
• cabinet design,
• door locks,
• cooling system.
• 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.
