Configure lift 2–8 as 2–8 (set the switch to position 5 for lift 5, e.g.).
Audio Unit Connection
Connect up to 5 Audio Units to each splitter. As the splitter has only 3 audio unit
terminals, connect 1–2 Audio Units in parallel. Remove the slide-on terminals from the
audio unit connectors and connect the twin-wire. Adhere to polarity to avoid the Audio

connection polarity.
Requirements
Connect up to 2 Audio Units to one terminal.
With multi-strand cables, always use a pair of wires which match each other. In
standard UTP cables the paired wires are twisted around each other.
With special cables (to the cabin), use the neighbouring wires and make sure
that the nearest surrounding wires do not radiate interference (power wire, video
signal etc.).
Recommendation
Do not run the bus near power wires, especially long sections.

Branch the bus to shorten the total length of sections
Lift Blocking Function Connection
Lift blocking is enabled by the contact breaking (opening) when there is a telephone
line (PSTN, GSM, UMTS) fault or if the

flat. Connect the contact to the relevant input of the control electronics of the lift/group
of lifts. The control electronics must ensure that, after the contact opening, the lifts in
operation go down to the nearest station and the doors open.
Termination Resistance
Warning
The bus is electrically isolated from the telephone line circuits according to
the EN60950 standard requirements and its low voltage cannot cause any
electrical accident.
Caution
This function may be mandatory depending on the regulations applicable
and time of installation.
for the given country
Caution
There is one more pin between the main bus connector and lift number
configuration, which helps you configure the termination resistance on the
last splitter connected (the furthest from the
).
CU
The termination resistance jumper is disabled by default.
