Planning instructions
NOTE
Planning and application instructions for the system are available in system
manual for ABB-free@home
®
. This can be downloaded via
www.abb.com/freeathome.
NOTE
Transmitter and receiver communicate via radio control. The transmission range
depends on the structural conditions. Walls and ceilings, especially steel
reinforcements or metal claddings, reduce the transmission range. The distance
of components to each other and to other transmitters that also emit high-
frequency signals (e.g. computers, audio and video systems) should be at least
1 m.

Safety instructions
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 users 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.).
■
Observe the correct polarity.
