Setup and installation
The steps to setup the device are as follows:
1. connect the load LEDs to the output terminal blocks
“OUT” of the device.
2. connect the local command to INPUT terminal blocks
and / or connect the DALI bus to the related terminal
blocks;
3. connect the 12/24 Vdc power supply to the terminal
blocks “DC IN” of the device.
As an alternative to using local commands, a DALI / KNX
Gateway can be connected to a KNX pushbutton.
INSTALLATION TECHNICAL NOTES
• Installation and maintenance must be
performed only if the power supply has
been turned off.
• Installation and maintenance must only
be performed by qualified personnel in
compliance with current regulations.
• The product must be installed insi-
de an electrical panel protected against
overvoltages.
• The product must be installed in a verti-
cal position with the front / label facing
the front or in a horizontal position with
the front / label facing upwards. Other
product installation positions are not al-
lowed. The bottom position with the front
panel / label facing down is not allowed.
• Keep separated the circuits at 230V (LV)
and the circuits not SELV from circuits
to low voltage (SELV) and from any con-
nection with this product. It is absolutely
forbidden to connect, for any reason
whatsoever, directly or indirectly, the
230V mains voltage to the bus or to other
parts of the circuit.
!
Before removing the device, be sure that inputs, outputs,
and the DC power supply have been disconnected. By
using a screwdriver, slide the locking device down and
remove the device from the profile rail.
DALI bus line and command connections
The connection to the DALI bus network and the local
commands is done via the screw terminal, located on the
front of the device in the upper part.
The length of the connection cables between the local
commands (N.O. Pushbutton, 0-10V, 1-10V, Potentiome-
ter or other) and the product must be less than 10m; the
cables must be dimensioned correctly and they should be
isolated from every wiring or parts at voltage not SELV.
Use double insulated shielded and twisted cables.
The length and type of the connection cables to the DALI
bus must be compliant with the protocol specification and
with the present regulations and they should be isolated
from every wiring or parts at voltage not SELV. Use dou-
ble insulated shielded and twisted cables.
All the devices and the control signal connected to the
DALI bus and to the local command (N.O. Pushbutton,
0-10V, 1-10V, Potentiometer or other) must be SELV (the
devices connected must be SELV or supply a SELV si-
gnal).

b) Place the support clamping tooth on the top edge of the mounting
rail and rotate device and support towards the guide until it completely
engages
c) Once fastened, connect the bus line, the inputs and the outputs
Installation scheme
Note.
When mounting the device in boards and ca-
binets it shall be provided the necessary ventilation
so that the temperature can be kept within the ope-
rating range of the device.
