Description of inputs and outputs

Up to 64 devices with a DALI interface can be connected to the DALI output. The DALI gateway is a DALI
master with integrated DALI power supply.
Important
Other DALI masters must not be connected to the gateway output.
Connecting another master to the Single-Master system can cause communication malfunctions.
Caution
Other DALI power supplies must not be connected to the gateway output.
Connecting another DALI power supply can add to the DALI currents which in turn may irreparably
damage the DALI input stages on the ballasts.
Inadvertently connecting 230 V mains voltage to the DALI output will not destroy the DALI output stage
as the output has built-in protection.
A control cable – maximum length below – can be used on the DALI output:
Cable length [mm
Max. cable length [m] from DG/S to DALI device
These values are rounded resistance values. EMC influences are not considered. For this reason, the
values should be considered as absolute maximum values.
It is possible to assemble the DALI control cable with conventional installation material for mains cables.
The two cores of the five-core NYM 5x1.5 mm
It is not mandatory to lay a separate control cable.
DALI control cables are isolated from the power supply by basic insulation properties according to EN 410.
SELV properties do not feature.
The device is ready for operation after connection of the gateway supply voltage. The green operating LED
on the front of the device lights up.
Note
The initialization phase will terminate if more than 64 DALI devices are connected and the information
will be displayed by group objects on the KNX or in the ABB i-bus
The initialization phase starts automatically after download, gateway supply voltage recovery and KNX bus
voltage recovery. In this phase, the gateway checks the system and addresses new, non-addressed DALI
devices if addressing is enabled. Initially the gateway assumes that the DALI system is unchanged and
immediately sends incoming KNX commands to the DALI, so that if the system has not changed, the
lighting can still be controlled during the initialization phase. Meanwhile, analysis of the DALI installation
runs in the background.
The initialization phase also runs if Enable automatic DALI addressing has been deactivated.
