outdoor installations, thanks to the die cast alumi
nium body and the stainless steel AISI 316 head.
The luminaire can be installed either upside down
on ceilings, or on side walls.
If you wish to install the fixture on false ceilings or
on drywalls, you can install directly the unit
without the need of recessed box. It is your job to
ensure a stable fixing, depending on the type of
structure on which you are going to install the unit.
POWER SUPPLY
Disconnect the mains voltage from the system.
Connect the red line labeled with "+24V DC" to
the positive output of the power supply; connect
the black line to negative output of the power
supply. Pay attention not to reverse the terminals:
a wrong polarity may seriously damage the devi
ce. In the case of multiple parallel connections of
inground luminaires, it is recommended to use ca
bles with at least 2.5mm
2
cross section or larger,
according to the voltage drop calculations.
Also, the light can be dimmed using an external
optional PWM dimmer (not included). Please refer
to the instruction manual of the dimmer for
connection details. However, due to the internal
electronics, the regulation is not smooth and takes
place at discrete levels.
When choosing the proper power supply unit you
have to consider the total power consumption of
all the devices connected in the same supplied
group; once this value is known, it will be possible
to choose among the vast range of power supply
units offered by Arena Luci.
It is recommended to leave a margin of at least
the 25% less than the driving capability of the
supply unit.
Connect the power supply to the mains outlet,
paying attention to right polarity LNE labelled on
the wiring terminals (colours: brown = L, blue = N,
green/yellow = E). Check the output voltage is
compatible with the specifications of the inground
and the optional dimmer.
