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

1) Terminal block for KNX bus line

2) Programming LED

3) Programming pushbutton

4) 6-pole terminal block

5) 4-pole terminal block

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 NTC sensors (only for EK-CG2-TP version)

Connection of outputs

The connection of the outputs is made with the screw

terminal blocks (4) and (5) inserted into the 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

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.
