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 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 and
the circuits not SELV from circuits to low
voltage (SELV) and from any connection
with this product. It is absolutely forbid-
den to connect, for any reason whatsoe-
ver, directly or indirectly, the 230V mains
voltage to the bus or to other parts of the
circuit.
!
All the devices and the control signal connected to the
DALI bus and to the local command (where available)
must be SELV (the devices connected must be SELV or
supply a SELV signal).
Characteristics of the DALI terminal block
•
Screw tightening of the conductors
•
Command and bus wiring: 1.5 mm
2
solid – 1.0 mm
2
stranded – 16 - 17 AWG
•
Conductor stripping recommended: 5.0 - 6.0 mm
•
Maximum length of the connection between dimmer-
driver and control device < 10 m
•
Length of bus 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 certified protection earth.
Insert the mounting support in the appropriate shaped
profile of the back side of the device, then hook the teeth
to the profile guide starting from the bottom. Finally, push
the upper part towards the guide for final coupling.
DALI bus line and command connection
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.
For the EK-GD2-DL-1-LV device, the length of the con
-
nection cables between the local commands (if available)
and the product must be less than 10m; the cables must
be correctly dimensioned and they should be isolated
from every wiring or parts at voltage not SELV. Use dou
-
ble 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
the present regulations and they should be isolated from
every wiring or parts at voltage not SELV. Use double in
-
sulated shielded and twisted cables.

Setup and installation
The steps for installing the device are as follows:
•
connect the loads to the “LED OUT” output terminals
of the device;
•
for the EK-GD2-DL-1-LV model, connect the local com
-
mand to the “PUSH” input if you want to use the “stand-
alone” mode;
•
connect the DALI bus to the related DA terminal blocks;
•
connect the 12/48 Vdc power supply to the terminal
blocks “DC IN” of the device.
All the devices and the control signal connected to the
DALI bus and to the local command (where available)
must be SELV (the devices connected must be SELV or
supply a SELV signal).
