4 Setup and function
4.1 Introduction
The ABB-free@home
(MDRC) for installation in the distributer on a mounting rail according to DIN EN 60715.
In applications in which a central device (e.g. a weather station) is to be made available for
several ABB-free@home
The USB interface is connected to the System Access Point via USB (Type B). All USB
interfaces in a building are then interconnected via a Twisted Pair cable.
The central line, like all individual ABB-free@home
free@home
®
power supply and a System Access Point for configuring the weather station.
The device is connected to the System Access Point via a Type B USB cable and is operational
as soon as the USB is connected. The USB-Interface, MDRC does not need to be configured,
since this takes place automatically via the System Access Point.
The operating status is displayed via 3 LEDs. The bus part and the USB part are isolated
galvanically from each other.

6.1 Requirements for the electrician
Danger - Electric voltage!
Install the device only if you have the necessary electrical engineering
knowledge and experience.
■
Incorrect installation endangers your life and that of the user of the electrical
system.
■
Incorrect installation can cause serious damage to property, e.g. due to fire.
The minimum necessary expert knowledge and requirements for the installation
are as follows:
■
Apply the "five safety rules" (DIN VDE 0105, EN 50110):
1. Disconnect
2. Secure against being re-connected
3. Ensure there is no voltage
4. Connect to earth and short-circuit
5. Cover or barricade adjacent live parts.
■
Use suitable personal protective clothing.
■
Use only suitable tools and measuring devices.
■
Check the type of supply network (TN system, IT system, TT system) to
secure the following power supply conditions (classic connection to ground,
protective earthing, necessary additional measures, etc.).
Danger - Short-circuit in the low-voltage line
■
Risk of death due to short-circuit
■
Risk of death due to electrical voltage of 230 V during short-circuit in the lowvoltage line.
– During mounting observe the spatial division (> 10 mm) of SELV electric
circuits to other electric circuits.
– If the minimum distance is insufficient, use electronic boxes or insulating
tubes.
– Observe the correct polarity.

7 Commissioning
7.1 Initial commissioning
The device connected to the bus line is automatically recognized by the system after a few
seconds. Parameterisation is not required.
– All devices connected to the central line are now recognised automatically and displayed
consecutively in the Web application.
– Devices on the central line, e.g. the weather station, cannot be configured from the
individual system, but only with the System Access Point.
– It can take up to 10 minutes until all devices are displayed. This can be accelerated by
carrying out a reset for the line.
