must
be placed onto the mounting plate (D2). You
should then slide it in the direction of the arrow until the
clamps (D3) click into place.

Connection of an External Contact
An external contact can be connected to the binary input
wave via plug-in terminals (C3) on the rear of the radio-
controlled sensor. The external contact can be con-
nected electrically in series with the reed contact in the
radio-controlled sensor or can be used on its own.
Note:
Due to the low voltage and low current levels that
are used for the contact surveillance (to ensure a long
battery life time), only encapsulated contacts as those of
reed relays or measuring relays should be used.
Use internal contact only
Diagram E1 indicates the plug-in terminals of the binary
input in the supplied state. It has been set via the wire
jumper between terminals 3 and 4 that only the internal
contact is used.
Use external contact only
Diagram E2 indicates the terminal assignment when only
an external contact should be used. The internal contact
has been deactivated via the wire jumper between ter-
minals 1 and 2.
Use internal and external contact
Diagram E3 indicates the terminal assignment if the in-
ternal and an external contact should be used together.
The wire jumper is omitted in this case.

Strain relief
The cable can be fixed to the external contact via the
supplied clamping plate (C5). The maximum permitted
diameter of the connecting cable is 5 mm.
Note:
The binary input sends a switching command OFF
when the internal contact or an external contact is closed
and an ON switching command when they are opened.

Commissioning
Note
When commissioning a binary input wave, it must be
linked via “learning telegrams” to the KNX radio-
controlled devices which should process its radio tele-
grams. Only those radio-controlled devices which are
able to process a switching command (ON/OFF) can be
connected to a binary input. These devices are e.g. a
universal dimmer insert sys or a switch insert sys in con-
