Electrical voltage
Mounting, installation and servicing
work on electrical devices may only
be performed by a suitably qualified
electrician.
• Observe the DIN EN 60065
standard! When establishing the
electronic connection, observe the
requirements of VDE 0805 or
EN 60950.
• Never lay parallel to high-
frequency conducting or highly
interference-contaminated cables.
• Observe the planning and installa-
tion guidelines for Multi systems.
Electrostatic charging
As a result of electrostatic charging,
direct contact with the circuit board
can result in destruction of the
device. Direct contact with the circuit
board must therefore be avoided.

Installation
Installation can be performed in any
optional form as parallel cabling.
We recommend side circuit or rising
mains systems with storey-by-storey
distribution. The coaxial cables are
installed in star formation from the
storey distribution board.
It is advisable to avoid pure star
or ring-main type systems.
Conductor material
Use twisted-pair, shielded cable
JY(St)Y with 0.8 mm cross-section as
installation material.
Cores 1 and 2 must generally be
doubled in side circuits, cores used
for video supply +Vp and 0V must
also be doubled.
Range
With 0.8 mm core diameter, the
maximum range is 800 or 1000 m.
Power supply
The system telephones are supplied
with 24 V DC (22-28 V). The supply
voltage must never be permitted to
drop below 22 V under load.
Mounting
The devices are intended as standard
for wall mounting. A 55 mm junc-
tion box must always be provided
under the system telephone cable
entry as a terminal and storage
space.
Strip back cable to appr. 80 mm.
1 Recommended mounting height
appr. 1.50 m to centre device.
2 Open the device from the back by
pressing in the locking lever.
3 When mounting directly on the
wall, fasten the base plate using
4 screws, paying attention that
the plate is the right way up (top
marking).
4 When mounting on a switch box,
use the screw openings in the centre
of the device, paying attention that
the plate is the right way up (top
marking).
Perform the installation in accord-
5
ance with the PS diagram. Connect
the coaxial cable and video supply
on the circuit board.
6 The cores of the installation cable
must be stored inside the free instal-
lation space in the base plate.
7 Insert the coloured plug of the
spiral cable into the socket at the
housing. A distinct click is audible
when the plug is correctly inserted.
8 Insert the other end of the spiral
cable into the receiver until the plug
clicks audibly into place. This con-
nection can no longer be detached.
9 Slot the housing into the base
plate and close by applying a light
pressure.
