Connection of the KNX bus line
The connection of the KNX bus line is made with the
terminal block (black/red) 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 a
KNX bus power supply (e.g. ekinex EK-AB1- TP or EK-
AG1-TP).
The
use
compromise the communication and damage the devices
connected to the bus.
Connection of the 230 Vac line (all version)
The connection of the line is made with screw terminals
located on the upper front of the device.(Figure A).
Characteristics of the terminals
•
screw clamping of conductors
•
maximum cross section of conductor 2.5 mm²
(single wire)
•
recommended wire stripping approx. 6 mm
•
torque max 0.8 Nm
Warning! The electrical connection of the device can be
carried out only by qualified personnel. The incorrect
installation may result in electric shock or fire. Before
making the electrical connections, make sure the power
supply has been turned off..

The outputs that are not used for the command of the
terminal temperature control can be configured in ETS
for the control of actuators of lighting or drive .
Example
T
EK-HA1-TP:
3-speed fan, 2-pipe system, application with use of the internal
regulator and room sensor or on the recovery. attention to the
electrical connections. The outputs V1, V2, V3 and C1 must be
powered externally ( terminals 11 and 15) with the power phase:
because the system functions you must connect the other end of the
motor fan and the other end of the actuator to the conductor neutral.
