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.
!
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 3-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
Connection of inputs
Inputs are connected by means of the 6-poles screw ter
-
minal block (4), inserted into the proper slot of the hou
-
sing.
Characteristics of the terminals
•
screw clamping of conductors
• maximum cross section of conductor 1 mm²
•
recommended wire stripping approx. 5 mm
•
torque max 0.2 Nm
In case of input connections longer than 1 m,
shielded cables must be used. In any case, do not
exceed 5 m in length.
Warning!
If configured as analogic, to an input
channel it is allowed exclusively the connection of a
NTC temperature sensor with a characteristic resi-
stance value of 10 kΩ at 25°C, β = 3435.
!
Connection of outputs
Outputs are connected by means of the screw terminal
blocks (4), inserted into the specific slots of the housing.
Characteristics of the terminals
•
screw clamping of conductors
• maximum cross section of conductor 1 mm²
•
recommended wire stripping approx. 5 mm
•
torque max 0.2 Nm
