3. Function
Correct use
–Only suitable for use in indoor areas with no drip and no spray water.
–Switching of incandescent lamps, HV halogen lamps, uorescent lamps, compact
uorescent lamps, dimmable energy-saving lamps, 230 V LED lamps and electronic or
inductive transformers with low voltage halogen lamps
–Installation into wall box according to DIN 49073
–Operate with suitable application module (see Chapter 6.3, "Accessories")
–Connection of extension unit push-button (NO contact), and motion detector extension unit

No mixed load operation of capacitive and inductive loads at the output.
4. Operation
These instructions describe the installation of the switch insert. The operation and function of
the application modules are described in the instructions of the respective application module.

The operation of extension units is only possible if a cover is attached to the main unit.
5. Information for electricians
5.1 Installation and electrical connection
DANGER!
Touching live parts can result in an electric shock.
An electric shock can be lethal.
Disconnect the connecting cables before working on the device and cover all live
parts in the area!
