Operating instructions

1 Safety instructions

Electrical devices may only be mounted and connected by electrically skilled persons.

Serious injuries, fire or property damage possible. Please read and follow manual fully.
The radio communication takes place via a non-exclusively available transmission path, and is

therefore not suitable for safety-related applications, such as emergency stop and emergency
call.

These instructions are an integral part of the product, and must remain with the end customer.

application basics for the KNX radio system.

Planning, installation and commissioning are carried out with the aid of KNX-certified software
of version ETS5 or higher. You can find the up-to-date product database, technical descriptions
and Declaration of Conformity on our Internet site.

Energy saving mode

The device switches to the energy saving mode after a preset time. In energy saving mode, the
LEDs remains switched off. During operation, the energy saving mode is exited.

Operations from the energy saving mode are executed immediately.
