Description
The ekinex®power supply EK-AG1-TP is a KNX device
for rail mounting which produces and monitors the 30 Vdc
voltage required to operate the bus system. The device
is equipped with an additional output 30 Vdc that may be
used for the auxiliary power supply of other SELV devices.
The device has an integrated choke which provides the
decoupling between the power supply and the information
on the bus line. On a KNX bus line can be connected up
to 64 KNX bus devices. The total current absorbed from
the two outputs (KNX bus and auxiliary) cannot exceed
640 mA. The output is protected from overload and short
circuit. The device can support short interruptions of the
mains voltage (max 200 ms).
Functions
• 30 Vdc SELV power supply for a KNX bus line with max
64 connected devices
• Auxiliary power supply 30 Vdc
• Reset of the connected bus line with a dedicated pu-
shbutton
Main characteristics

Planning
Planning a KNX bus installation, the use of a 640 mA po-
wer supply unit requires to take into account the following
guidelines:
• the maximum number of bus devices connected is 64;
• the maximum length of a line segment is 350 m, mea-
sured along the line between the power supply and the
furthest device bus;
1) Terminal blocks for power supply 110-230 Vac 50/60 Hz
2) Reset pushbutton
3) Reset LED (red)
4) Terminal block for KNX bus line
5) Terminal block for auxiliary output 30 Vdc
6) Overload/short circuit LED (red)
7) Output voltage LED (green)

• the maximum distance between two bus devices can-
not exceed 700 m;
• the maximum length of a bus line is 1000 m, keeping into
account all segments.
At the same bus line can be connected not more than two
power supplies. A second power supply may be necessa-
ry when the installation in distribution boards requires a
particular concentration of the bus devices (tipically more
than 30 units installed within 10 m). In this case a po-
wer supply has to be installed near the group of devices.
Between two power supplies installed on the same bus
line a minimum distance of 200 m is required, measured
along the line.
• screw clamping of conductors
• maximum cross section of conductor 2.5 mm²
• recommended wire stripping approx. 6 mm
• torque max 0.5 Nm

Electrical connections
Main supply 230 Vac
The connection to the 230 main supply Vac is made with
screw terminals ( , L, N) located on the upper front of the
device. Characteristics of the terminal blocks:
EKINSTGUIDAEKAB1TP
Note. When mounting the device in boards and ca-
binets it shall be provided the necessary ventilation
so that the temperature can be kept within the ope-
rating range of the device.
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.
Mounting
The device has degree of protection IP20, and is the-
refore suitable for use in dry interior rooms. The hou-
sing is made for rail mounting according to EN 60715
in boards or cabinets for electrical distribution. The
installation is in horizontal position, the correct posi-
tion is when the terminals for KNX bus line and auxi-
liary output are located at the bottom and the terminals
( , L, N) for connecting the mains power supply 230 Vac
are located at the top. For the installation of the device on
the rail proceed as follows:
• with the aid of a tool bring the locking device in the fully
lowered position (1);
• place the upper edge of the rear inner prole on the
upper edge of the rail (2);
• rotate the device towards the rail (3);
• push the locking device upward until it stops (4).
Before removing the device, be sure the bus terminals
have been extracted from their slots. Use a screwdriver
to slide down the locking device and remove the device
from the rail.
KNX bus line
The connection to the KNX bus line is made with the ter-
minal block (black/red) included in delivery and inserted
into the slot located on the bottom left part of the front.
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 codication: red = + (positive) bus conductor,
black = - (negative) bus conductor
Auxiliary output
The auxiliary output 30 Vdc is provided with a dedicated
terminal block (yellow/white) included in the delivery and
inserted into the slot located on the bottom right part of
the front. The terminal block for the auxiliary output has a
color codication di󰀨erent than that for the connection of
the KNX bus. Characteristics of the 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 codication: yellow = + (positive) AUX conductor,
white = - (negative) AUX conductor
To connect the auxiliary output to the powered devices it
is recommended to use a cable with a sheath of di󰀨erent
color than that used to connect the KNX bus line.

Maintenance
The device is maintenance-free. To clean use a dry cloth.
It must be avoided the use of solvents or other aggressive
substances.
Warning! The electrical connection of the device
can be carried out only by qualied personnel. The
incorrect installation may result in electric shock or
re. Before making the electrical connections, make
sure the power supply has been turned o.
Warning! Incorrect disposal of this product may
cause serious damage to the environment and hu-
man health. Please be informed about the correct
disposal procedures for waste collecting and pro-
cessing provided by local authorities.
Reset
The device has a reset pushbutton. After a reset, the bus
line is not powered for 20 seconds and the bus devices
connected are restored to their original condition. During
this interval of time the reset LED (red) is turned perma-
nently on.
Failure
When the red LED, labeled “I> Imax”, is turned on, this
means that the KNX output is overloaded or short-circu-
ited. The problem can be solved by removing the cause
of the short circuit or by reducing the number of KNX de-
vices connected to the line. After the removal of the pro-
blem only the green LED “ON” is turned on, at this time it
is recommended to reset the line.
