2 Safety
2.1 General safety instructions
►
Protect the device from moisture, dirt and damage during transport, storage and operation.
►
Operate the device only within the specified technical data.
►
Operate the device only in a closed housing (distribution board).
►
Mounting and installation must be carried out by qualified electricians.
►
Disconnect the device from the supply of electrical power before mounting.
2.2 Proper use
The device must be installed centrally in an electrical distribution board.
The device is a modular DIN rail component for quick installation in distribution boards on 35 mm mounting
rails according to EN 60715.
2.3 Cyber security (network security)
The industry is increasingly faced with cyber security risks. To increase the stability, security and
robustness of its solutions, ABB has introduced official robustness tests for Internet security as part of the
product development process.
In addition, the information below includes guidelines and mechanisms that you can use to improve the
security of KNX systems.
2.4 Preventing access to the different media
The basis for any protection concept is the careful shielding of the system against unauthorized access.
Only authorized persons (installers, janitors and users) should have physical access to a KNX system. The
critical points of every KNX medium must be protected as well as possible during planning and installation.
In general, applications and devices should be permanently installed to prevent their easy removal and in
this way prevent access to the KNX system for unauthorized persons. Sub-distributions with KNX devices
should be closed, or in rooms to which only authorized persons have access.

ABB i-bus®KNX
Safety
12 2CDC508198D0211 Rev. A | AC/S 1.x.1
2.5 Twisted pair cabling
►
The ends of KNX twisted pair cables should not be visible or protrude from the wall either inside or
outside the building.
►
If available, use the anti
-theft devices on the application modules.
►
Bus cables outdoors repr
esent an elevated risk. Ensure that physical access to KNX twisted pair
cables is especially difficult here.
►
For extra security, devices installed in areas with limited protection (outdoor areas, underground
parking lots, restrooms, etc.) can be
designed as a separate line. Enabling the filter tables in the line
coupler (KNX only) prevents attackers from gaining access to the whole system.
2.6 IP cabling inside the building
For building automation, use a separate LAN or WLAN network with its own hardware (routers, switches
etc.).
Regardless of the KNX system, apply the usual security mechanisms for IP networks. These are
examples:
•MAC filter
•Encryption of wireless networks
•Usage of strong passwords and protection of these against access by unauthorized persons
Note
The device cannot be reached during IP, TCP or UDP flooding (access from the internet). To prevent this
reaction, set a data rate limit at network level.
Please discuss this with your network administrator.

Safety
AC/S 1.x.1 | 2CDC508198D0211 Rev. A 13
2.7 Connection to the Internet
KNXnet/IP routing and KNXnet/IP tunneling use unencrypted data transfer and is therefore not intended
for use on the public internet. For this reason router ports in the direction of the internet must not be
opened: this action will ensure KNX communication is not visible on the internet.
Systems can be accessed via the internet in the following ways:
•Access to KNX installations via VPN connections. However, this requires a router with VPN server
functionality or a server.
•Use of manufacturer-specific solutions or visualizations, e.g. access via https.
2.8 Open IP network ports
The device uses the following network ports for data communication in the IP network. It is to be ensured
that only authorized systems have access to these network ports.

3 Product overview
3.1 Product overview
The devices are modular DIN rail component (MDRC) in the pro Mdesign. The module width of the
devices is 4 space units. The devices are designed for installation in distribution boards on 35 mm
mounting rails.
The devices are powered by the bus and require an additional supply voltage, either 24 V AC/DC or Power
over Ethernet (PoE).
The device connects to the ABB i-bus®KNX via the front bus connection terminal.
The software application Engineering Tool Software (ETS) is used for physical address assignment and for
setting the parameters.
The device is ready for operation after connecting the bus voltage and the supply voltage.

Fig. 1: AC/S 1.1.1 device illustration
Automation controller with pre-defined automation modules for comprehensive heating, ventilation and air
conditioning automation (HVAC automation). For use from central systems to room automation, supports
the achievement of energy efficiency goals such as EN 15232.
The device contains pre-defined application-specific automation modules (ASM) for the most common
areas of application, for instance the calculation of heat demand, trends or schedulers. You can create
your own automation modules using a graphic logic editor.
The device has a web user interface for the display of data and operation; this interface is generated
automatically.
Commissioning is undertaken entirely in ETS version 5.6.5 or later. Additional external software is not
required. The device has a KNX TP connection and requires a supply voltage of 24 V AC/DC or PoE for
operation.

Table 7: Device type AC/S 1.1.1
Note
ETS and the current version of the device application are required for programming.
The latest version of the application and corresponding software information are available for download
from www.abb.com/knx.After import into ETS, the application appears in the Catalogs window under
Manufacturers/ABB/Heating Ventilation Air conditioning/Automation Controller.
In addition to the ETS application, you will require ETS DCA "ABB AC/S" for commissioning; this can be
obtained free of charge from the KNX online shop.
The device does not support the locking function of a KNX device in ETS. If you use a BCU code to
inhibit access to all the project devices, it has no effect on this device. Data can still be read and
programmed.
Note
The application "HVAC Application/1.0" and the DCA "ABB AC/S" are supported in ETS 5 only from
version 5.6.5. Earlier versions are not supported.
