WARNING!
Danger of death through electric shock or fire!

Installation should only be carried out by professional electrician!
Disconnect the mains power supply prior to installation and/or disassembly!
Follow the detailed KNX manual on the Internet!

General information

The flush-mounted actuator DU 1 DALI S RF KNX with wireless function conforms to EN 60669-2-1 if correctly installed.
DALI-2 certified
It provides the interface between the KNX bus system and the DALI lighting system (Digital Addressable Lighting Interface).
It has 1 channel for DALI lighting control; control is via broadcast telegram, i.e. all participants on one channel are switched/ dimmed simultaneously.
It can be installed with conventional push buttons/switches in flush-mounted boxes.
The ETS (Engineering Tool) can be used to select application programmes, assign specific parameters and addresses and transfer them to the device.

This device supports KNX Secure. For start-up, the Factory-Default-Setup-Key (FDSK) is required (sticker on the device and the secure card).
Keep the Factory-Default-Setup-Key in a safe place.
Remove the stickers from the device for maximum safety. If the FDSK is lost, a recovery is not possible. In this case, start-up is only possible „insecure“. DALI DU 1 RF KNX 1 Way Wireless Flush - Figure

Designated Use

The actuator controls the connected DALI lamps in brightness, colour and colour temperature (depending on the device types supported by the DALI lamps). It is designed as a Broadcast Single Master and is DALI-2 certified. Due to broadcast communication, no individual addressing of the DALI lamps is required. All DALI lamps connected to a channel respond together to broadcast com- mands and cannot be controlled via group or individual commands.
For use in residential and other buildings (office buildings, public buildings, hotels etc.)
Use only in closed, dry areas

Installation

For installation in conventional flush-mounted boxes (according to DIN 49073).

Connection
Risk of electric shock!

The inputs carry mains voltage! When connecting the inputs or before any intervention at one of the inputs, interrupt the 230 V supply of the device.
Protect against accidental contact during installation.
Do not connect mains voltage (230 V) or other external voltages to the extension inputs!
Do not remove the insulation from the unused auxiliary inputs.
Do not connect an additional DALI power supply in parallel.
For the entire DALI installation of a segment, a maximum cable length of 300 m must not be exceeded (Ø 1.5 mm²).
Connect the cable for the DALI bus to terminals DA+/DA–.

Start up via direct control (factory setting)
Via input I1, manual operation (one-button operation for dimming, without parameter setting) is possible. This can be changed with the ETS.
