POWER SUPPLY INSTALLATION

The power supply must be installed in a dry place away from direct heat or dust.
Ensure easy access for inspection and maintenance. Secure the unit to the wall
with the anchor bolts provided or insert it into a rack with a omega DIN bar. Be-
fore connecting the unit use a tester to make sure that the cables are not broken
or short-circuited. For user safety, the equipment operates at a low voltage and
is separated from the mains by a high-insulation transformer. We recommend
installation of an overload cutout of appropriate capacity between the mains and
the unit. To complete the installation, proceed as follows:
1) Make the cabling connections to the terminal block in accordance with the
diagrams enclosed with this manual.
2) Connect up the power terminal block located beneath the rear cover.
3) Power up the power supplier. Once correctly powered up, only the red "pow-
er-on" LEDS (L1 to L6) for the entrance panel, interphones and monitors
must be illuminated.
The same rule also applies to all the other units in the system. In the case
of entrance panels equipped with video camera and external video camera
units, due consideration must also be given to the following:
4) The video camera operates within a temperature range of -5° to +50°C. To
prevent the unit from overheating, it must therefore be protected from the
sun's rays by a roof or shield.
5) The lens must not be exposed to direct light beams (sun rays, car headlights
etc.).
6) The caller must be illuminated frontally. If lighting is insufficient, use a sup-
plementary external lamp powered from the mains.
GENERAL CABLE INSTALLATION INSTRUCTIONS
Correct DIGIBUS installation requires the following factors to be taken into ac-
count:
- the installation site
- the size of the installation
The equipment is fully compliant with the "CE" mark and directives 2004/108/CE
and the following regarding the Community safety standards and the electromag-
netic compatibility. Nonetheless, for correct installation, the following precautions
must be taken:
- the system cables must be layed taking into account the overall length of the
system cabling; the cross-section of the cables increases with the overall
length of the installation as shown in the tables given below.
- the cables connecting the external/internal units and the power supply must
not be run together with power cables (230V or greater), but must be installed
in their own ducts.
TECHNICAL CHARACTERISTICS OF POWER SUPPLIER ART. 6948
The basic power supply unit for all DIGIBUS video electronic door opener sys-
tems, housed in a V-0 range technopolimeric case. Designed for mounting to
equipment panels with DIN omega rails (12 modules), or wall fixing with masonry
plugs.
Features inter-changeable cards and pull-out terminal blocks to facilitate rapid
maintenance. The power supplier is fitted with an acoustic call generator and 6
LEDS indicating the operating status.

Description of power supplier terminal functions:
M1-M2 Co-ax cable sheath through terminals.
V1-V2 Co-ax cable core through terminals
+1 Monitor disconnect control line.
This terminal is used by the entrance panels or switchboard to deacti-
vate the monitors before a new call and at the end of a conversation.
When terminal +1 is shorted to terminal 4, the voltage across the +
and - terminals passes through zero and remains at zero for the time
terminal +1 is short-circuited. LED L1 switches off to indicate the "zero
voltage" status of the + and - terminals.
CH Call signal activation control line.
This terminal is used by the entrance panels or switchboard to activate
the call generator in the power supplier. When terminal CH is shorted
to terminal 4, the call signal is activated by terminal 3. The signal re-
mains active for the time terminal CH is short-circuited.
S Door lock release control line.
This terminal is used by the entrance panels or switchboard to release
the door lock for the corresponding entrance panel or switchboard.
When terminal S is shorted to terminal 4, terminal S1 is shorted to
terminal 0 (15V rectified) and LED L2 illuminates. Terminal S1 remains
shorted for the time terminal S is activated.
F1 Auxiliary function 1 activation control line.
This terminal is used by the entrance panels or switchboard to activate
function F1. When terminal F1 is shorted to terminal 4, the voltage at
terminal R1 increases to 12 Vdc and remains at this voltage for the
time terminal F1 is shorted. Activation of the function is signalled by
illumination of LED L3.
