Connection of loads and power supply
The connection to the 90-230 Vac 50-60Hz power supply
is done via the screw terminals located in the lower part
of the device.
Characteristics of the supply and loads terminal block
• Screw tightening of the conductors
• Power and loads wiring: 1.5 mm2solid – 2.5 mm2stran-
ded – 16 - 13 AWG
• Stripping recommended approx.: 5.0 - 6.0 mm
• Max torque 0.5 Nm for screw terminals
Warning! The electrical connection of the appliance
must be carried out exclusively by qualied person-
nel. Incorrect installation can cause electrocution or
re. Before making the electrical connections, make
sure you have deactivated the mains voltage.

INSTALLATION TECHNICAL NOTES
• Installation and maintenance must be
performed only if the power supply has
been turned o.
• Installation and maintenance must only
be performed by qualied personnel in
compliance with current regulations.
• The product must be installed inside
a wall mounting box or an electrical pa-
nel, where it is recommended to install a
surge protector.
• The product must be protected by a sui-
tably sized fuse.
• The product must be protected by a su-
itably sized magnetothermic switch on
the main input line.
• The product must be installed in a verti-
cal position with the front / label facing
the front or in a horizontal position with
the front / label facing upwards. Other
product installation positions are not
allowed.
• Do not connect inductive loads.
• Do not connect to UPS (uninter-
ruptible power supply) with ou-
tput other than Pure Sine Wave.
The device is not grounded. Protection
from accidental contacts is guaranteed
by the casing.
• Use in thermally harsh environments
could limit the output power.
• In the system, keep the 90-230Vac circu-
its and the non-SELV circuits separate
from the SELV circuits at very low safety
voltage and from the KNX bus
• It is absolutely forbidden to connect, for
any reason whatsoever, directly or indi-
rectly, the 90-230Vac mains voltage to
the KNX bus or to the loads.
• Use double insulated cables.
Warning! To power the KNX bus lines, use exclusi-
vely KNX bus power supplies (e.g. ekinex EK-AB1-
TP, EK-AG1-TP or EK-AM1-TP). The use of other
power devices can compromise communication
and damage the devices connected to the bus.

Outputs
The cables connected to the outputs must be correctly
sized and must be isolated from any wiring or parts with
dierent voltages. The length and type of connection ca-
bles must comply with the regulations in force.
Conguration and commissioning
The conguration and commissioning of the device re-
quires the use of the ETS® (Engineering Tool Software)
V5 program or later versions. These activities must be
carried out in accordance with the design of the building
automation system created by a qualied professional.
To congure the device parameters, the corresponding
application program or the entire ekinex® product data-
base must be loaded into the ETS® program. For detailed
information on the conguration possibilities, consult the
application manual of the appliance available on the web-
site www.ekinex.com.
