Mounting
The device has degree of protection IP10, and is there-
fore suitable for use in dry interior rooms. The housing is
made for rail mounting according to EN 60715 in boards
or cabinets for electrical distribution. The correct mounting
is when the DC inputs screw terminal is located at the bot-
tom. When installing be sure to leave accessible only the
front panel; all other sides must not be accessible. For the
mounting proceed as follows:
• with the aid of a tool bring the locking device in the fully
lowered position (a);
• place the upper edge of the rear inner prole on the
upper edge of the rail (b);
• rotate the device towards the rail (c);
• push the locking device upward until it stops (d).
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.

INSTALLATION TECHNICAL NOTES
• Installation and maintenance must be
performed only if the power supply has
been turned o󰀨.
• Installation and maintenance must only
be performed by qualied 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.

Setup and installation
In order to setup the dip-switch, it is necessary to open
the device front cover, by means of a screwdriver as de-
tailed in the image below.

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 specication 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).
The 6-way dip-switch setting (under the front cover) o󰀨ers
a wide choice of possible congurations.

Conguration and commissioning
Conguration and commissioning activities of the device
must be carried out according to the design of the building
automation system done by a qualied planner.
For commissioning the device the following activities are
required:
• make the electrical connections as indicated above;
• power up the bus;
• carry out the device addressing, as described in the
product Datasheet and in the application manual.
Device addressing
• Simplied method: 1 ballast connected at a time
• Random Address Allocation
DALI channels maps
The intensity and ON / OFF switching of the output is ma-
naged via the DALI channel.
Characteristics of the DALI terminal block
• Screw tightening of the conductors
• Command & bus wiring: 1.5 mm2 solid – 1 mm2 stran-
ded – 30 - 14 AWG
• Command & bus stripping: 6 mm
• Conductor stripping recommended approx. 10 mm
• Maximum length of the connection between dimmer-
driver and control device < 10 m
• Length of connection cables < 10 m
Connection of power supply and LEDs
For the power supply use SELV power suppliers with li-
mited current, short circuit protection only and the power
must be correctly dimensioned. In case of usage of a po-
wer supplier with ground terminals, all points of the pro-
tective earth (PE = Protection Earth) must be connected
to a valid and certied protection earth.
The connection cables between the power source “low
voltage” and the product must be correctly dimensioned
and they should be isolated from every wiring or parts at
not-SELV voltage. Use double insulated cables.
The power supply must be dimensioned according to
the load connected to the device. If the power supply is
oversized with respect to the maximum absorbed current,
then insert a protection against over-current between the
power supply and the device.
Characteristics of the supply and LEDs terminal block
• Screw tightening of the conductors
• Power & LEDs wiring: 2. 5mm2 solid – 1.5 mm2 stran-
ded – 30 - 12 AWG
• Power and LEDs stripping recommended approx.: 7.5
mm
• Max torque 0.5 Nm
Outputs
The length of the connection cables between the product
and the LED module must be less than 10m; the cables
must be correctly dimensioned and they should be isola-
ted from every wiring or parts at not-SELV voltage. It is
preferable to use shielded and twisted cables.
In case it is needed to connect the device and LED mo-
dules with cables longer than 10m, the installer must gua-
rantee the correct functioning of the system. In any case,
do not exceed 30m of the connection between the device
and the LED modules.

Signalling LEDs
On the device front panel a signaling LED is present. If
there is no BUS power supply or there is a BUS error,
the signaling LED ashes quickly (2 pulses per second).
If there is BUS power supply but a BUS error occurs, the
signaling LED ashes slowly (1 pulse per second). If the
BUS signal is connected and working correctly, the LED
remains on steady.
Relationship between DALI bus and local commands: on
power-up, in case the bus connection is not present, the
local command is active. When the BUS connection is
detected, the control passes to the BUS as long as the
signal is present. In the absence of the signal, if the local
command is an N.O. button, the control is passed to the
local commands when the button is pressed. On the other
hand, if the local command is 0-10V or 1-10V, the control
immediately passes to the local command.
