ABA/S 1.2.1 | 2CDC509086D0201 9
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.
►
Switch off the device supply voltage before mounting.
2.2 Proper use
The product must be installed centrally in an electrical distribution board.
The device is a modular installation device for quick installation in distribution boards on 35 mm mounting
rails to EN 60715.
2.3 Cyber security (network security)
The industry is increasingly faced with cyber security risks. To make its solutions more stable, secure and
robust, ABB has officially added cyber security tests to its product development process.
In addition, the information below includes guidelines and mechanisms that you can use to improve the
security of KNX systems.
Link to disclaimer, "Cyber Security Disclaimer for Products"
2.4 Restrict access to the various media
The basis of any protection plan is to isolate the system carefully against unauthorized access. Only
authorized persons (installers, janitors and users) should have physical access to a KNX system. During
planning and installation, the critical points of each KNX medium must be protected as effectively as
possible.
In general, applications and devices should be permanently installed to prevent them from being easily
removed, allowing unauthorized access to the KNX system. Sub-distributions with KNX devices should be
closed, or in rooms to which only authorized persons have access.

ABB i-bus®KNX
Safety
10 2CDC509086D0201 | ABA/S 1.2.1
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 lines in outdoor areas are an
increased 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. For example:
•MAC filters
•Wireless network encryption
•Use strong passwords and protect them from unauthorized persons
Note
The device cannot be reached during IP, TCP or UDP flooding (access from the internet). To avoid this,
set rate limiting at network level.
Please discuss this with your network administrator.
2.7 Connection to the internet
The device's web server uses unencrypted data transfer and is therefore not intended for use on the public
internet. To prevent KNX communication from being visible on the internet, ports must not be opened in
that direction by routers.
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.

3 Product Overview
3.1 Product Overview
The device is a modular installation device (MDRC) in Pro Mdesign. The module width of the device is
four space units. It is designed for installation in distribution boards on 35 mm mounting rails.
The device is supplied via the bus and requires an additional auxiliary voltage, either 24 V DC or Power
over Ethernet (PoE). We recommend using a power supply from our range. When using timer functions,
date and time must be provided via KNX/TP.
The device connects to the ABB i-bus®KNX via the front bus connection terminal.
Engineering Tool Software (ETS) is used for physical address assignment and parametrization.
Once the bus and auxiliary voltages are connected, the device is ready for operation.

The latest version of the application and corresponding software information is available for download
from www.abb.com/knx. After import into ETS, it appears in the Catalogs window under
Manufacturers/ABB/Controller/Controller Output.
The device does not support the locking function of a KNX device in ETS. Using a BCU code to inhibit

3.3.4.3 Description of inputs and outputs
SELV 24 V DC supply voltage input
Only a 24 V DC voltage may be connected to the power supply input. We recommend using a power
supply from our range.
CAUTION
The device must be powered either by a 24 V DC voltage or via PoE (Power over Ethernet) according to
IEEE 802.3af class 2.
Connecting the device to 230 V may destroy it!
KNX connection
The supplied bus connection terminal is used to connect to the KNX bus.
LAN connection
The device connects to the network via an Ethernet RJ45 interface for LAN networks. The network
interface can be operated at a transmission speed of 10/100 Mbit/s. Network activity is indicated by the
LAN/LINK LED on the front of the device.
The device features an AutoSensing function and sets the baud rate (10 or 100 Mbit) automatically.
