4 INSTALLATION

WARNING: the installation of the device must be
exclusively done by qualified personnel, following the regulations
in force and the guidelines for KNX/EIB installations.
Warnings for KNX/EIB installations
1. The length of the bus line between the KNX/DMX Gateway and the power supply unit must not exceed
350 metres.
2. The length of the bus line between the KNX/DMX Gateway and the most distant KNX/EIB device must
not exceed 700 metres.
3. If possible do not create ring circuits so as to prevent undesirable signals and overloads.
4. Keep a distance of at least 4 mm between the individually insulated cables of the bus line and those of
the electric line.
5. Do not damage the electrical continuity conductor of the shielding.
WARNING: the unused bus signal cables and the electric continuity cable must
never touch powered elements or the grounding cable!
Warnings for installation phase
Switch on the voltage supply.
The group addresses are coded by S1 when the DC voltage in KNX-DMX Gateway is switched on.
Soft-start (slow start-up to protect lights) can be adjusted using S2 and S3 sets the dimming function.
If turning the rotary switch afterwards has no effect, it can be reset using T1.
The Prg button on device inputs the physical addresses via a dummy application into the ETS.
