Spring for hooking on wall-mounting devices
The device can be hooked on the back of some ekinex
wall-mounting devices with the spring EK-MAR to be or-
dered separately (preventively check the compatibility).
Switching, display and connection elements
The device is equipped with a programming LED and a
programming pushbutton, a terminal block for connection
of the KNX bus line and screw terminal blocks for connec-
tion of inputs and outputs.
Switching and display elements
• pushbutton (3) for switching between the normal and
programming operating modes
• red LED (2) for indication of the active operating mode
(on = programming, off = normal operation)
Connection elements
• KNX bus terminal block (1)
• 6-pole (4) and 4-pole (5) screw terminals for connec-
tion of inputs and outputs

Connection of the KNX bus line
The connection of the bus line is made with the KNX ter-
minal block (1) included in delivery and inserted into the
slot of the housing.
Characteristics of the KNX terminal block
• spring clamping of conductors
• 4 seats for conductors for each polarity
• terminal suitable for KNX bus cable with single-wire
conductors and diameter between 0.6 and 0.8 mm
• recommended wire stripping approx. 5 mm
• color codification: red = + (positive) bus conductor,
black = – (negative) bus conductor

Warning! In order to supply the KNX bus lines use
only KNX bus power supplies (e.g. ekinex EK-AB1-
TP or EK-AG1-TP). The use of other power supplies
can compromise the communication and damage
the devices connected to the bus.
