MAINTAINED/NON-MAINTAINED (OPTIONAL) ILLUMINATION SIGNS WITH WHITE LEDs
GENERAL
These sign illumination luminaires use a new
technology, friendly to the environment, with high
illuminated L.E.D.s. L.E.D. technology has very low
power consumption.
The edge illumination sign is used as a maintained
emergency lighting with indications symbols.
In this type of marking panels, the PVC overlay is
mounted on the marking panel with 4 plastic screws,
and it can be changed by change the PVC overlay in
accordance with the desired result.
Each model combines modern, aesthetics, together
with functionality. The exit illumination signs are used
in every public area where clear direction and good
appearance are important.
NON MAINTAINED OPERATION
By default the illumination sign operates as maintained.
The device has a possibility to operate as non
maintained. To change the maintained to non-
maintained operation follow the relative instructions on
page 6.
All models must be permanently connected to the
mains power supply as shown on page 2.
The legend is screened on to a clear acrylic sheet
which has the marking on the marking panel with the
light that comes from the top of the luminaire and
diffracts, giving light to the marking panel.
The luminaire has an indication (CHARGE) for the
charging of the battery and a (TEST) button to TEST
the emergency circuit and the LEDs for good operation
only when the luminaire is powered by the mains power
supply. The unit must be mounted in a clearly visible
area and can either be hung on a ceiling or mounted on
a wall depending on the requirements of the
installation. The package includes all the required
materials for mounting on the wall or on the ceiling.
The pages 2,3 and 4 show us the mounting
methods.
WARNING !!
1. Read carefully this instruction manual.
2. Before service interrupt the mains power supply.
3. The device must be connected to the mains power
supply through a fuse dependent by the total amount of
the line’s power load.
4. It is suggested to check every month the indication
LED for battery charging, and by pushing briefly the
TEST button to check the emergency circuit. The sign
should light for a few seconds powered by the battery
and then, will turn to normal operation
5. full
by disconnecting the mains power supply
Count the autonomous duration of the luminaire and in
case of no correspondence to stated emergency
duration replace the battery The replacement of the
battery must be done using parts of the same type, by
the manufacturer or by a competent person.
7Replaced batteries must not be thrown into
trash bins. They must be returned to special
battery disposal points.
Do not incinerate.
NOTE: LED= Light Emitting Diode
LABELING EXPLANATION:
X: Self contained 1: Maintained (*)
A: Including test device G: Internally illuminated
safety sign. 180: 3 hour duration
(*) Maintained operation: The luminaire lights its
illumination source, when it is powered by the mains
power supply or not.
Non-Maintained operation: The luminaire lights its
illumination source, only in power supply’s failure.
. In the opposite
condition contact the installer.
Every six months, a duration check should be
carried out .
.
6. In case of inactive use for a period greater than 2
months, disconnect the battery by pulling out the
battery’s connector.

Use a certified electrical box 250V AC (IP40) to
perform the electrical connection, with minimum
internal space 35x35x25mm to install the 3 pole
terminal block. In this box install a certified 3 pole
terminal block 250V AC/16A 2,5mm² providing
terminals to connect the live wire L, the neutral N
and the ground GND. To this terminal block is
connected the power cable with a cross section of
1,5mm². Install the electrical box in an appropriate
area in the ceiling. Install securely the 3 pole
terminal block and perform the connection according to figure 3.
The electrical box and the 3 pole terminal block not included. Installation may require
advice from a qualified person.
