english You can route and connect the control cables yourself, since the
control signals are transferred with a low voltage of 12V.
1. The two-wire control cable (7) must be routed from each vacuum
socket along the tubes to the vacuum unit. The control cable is
attached to the tubes using the supplied cable ties (8).
2. The cable is connected to the branching point using a connector
block (14). Please ensure that the connections are fitted with
long-term protection from dirt and moisture. The branching so-
cket can be surface mounted or concealed.
3. Gather all the cables in the junction box (15) and connect them to
the control cable (16) with the aid of the connector block (14).
4. Check the continuity of the control cable before plastering.
The vacuum unit control cable is inserted into the vacuum unit so-
cket during stationary operation. The right or left connection can be
used (see also CENTIX operating instructions).

3.2 Installing the control
cable
Connecting control cable (7) to
vacuum socket:
5. To connect vacuum socket:
allow control cable (7) to pro-
trude from wall by approx. 20
cm for problem-free vacuum
socket (10) connection later.
The polarity is unimportant
when making the connec-
tion.
Tips + Tricks:
• The control cable can also be
routed in empty tubes (diam.
13.5 mm). The branching point
can be concealed in an empty
socket/branch socket. This keeps
the access to the contact points
open after plastering.
