1. Remove the cover (1) on the electronics box.
2. Connect the DIF cable (2), which is laid out ready,
either to the system control or to the mobile base
station.
3. If you are using a radio receiver, use the mobile base
station (3).
4. If you are using the wired system control, use the sys-
tem control (4).
5. Consult the instructions for the system control for in-
formation on coupling the mobile base station and the
system control.

Routing the cables

1. At lengths of 10 m or more, mains voltage connection
cables must be laid separately from sensor or bus lines.
Minimum clearance for the extra low-voltage wire and
power supply cable at a line length of > 10 m: 25 cm.

24V / eBUS
Route 24 V cables and eBUS cables through the left-
hand strain reliefs on the electronics box.
Route 230 V cables through the right-hand strain reliefs
on the electronics box.

Carrying out the wiring

Ensure that the mains voltage is correctly disconnected
from the safety extra-low voltage.
Only connect power supply cables to the terminals that
are marked for the purpose.
Shorten the connection cables according to require-
ments.

Strip the electrical wire as shown in the figure. In doing
so, ensure that the insulation on the individual conduct-
ors is not damaged.
Ensure the inner conductor insulation is not damaged
when stripping the outer sheathing.
Only strip inner conductors just enough to establish
good, sound connections.
Fit conductor end sleeves on the stripped ends of the
conductors.
Screw the respective plug to the connection cable.
Check whether all conductors are inserted mechanically
securely in the terminals of the plug. Remedy this if
necessary.
