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.

• rotate the device towards the rail (3);

• push the locking device upward until it stops (4).

Before removing the device, be sure that power supply

and controlled loads have been disconnected and the bus

terminal has been extracted from its slot. Use a screwdri-

ver to slide down the locking device and remove the de-

vice from the rail.

Connection of the KNX bus line

The connection of the KNX bus line is made with the ter-

minal block included in delivery and inserted into the slot

at the bottom 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 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.

Connection of the power supply

The connection of the 230 Vac or 24 Vac power supply is

made with the screw terminals (L, N) located at the top

front of the device.

Characteristics of the terminals

• screw clamping of conductors

• maximum cross section of conductor 2,5 mm²

• recommended wire stripping approx. 6 mm

• torque max 0,5 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.

Connection of the outputs

The connection of the outputs is made with the screw ter-

minals located at the top front of the device.

Characteristics of the terminals

• screw clamping of conductors

• maximum cross section of conductor 2.5 mm² (single-

wire) or 1.5 mm² (multi-wire)

• recommended wire stripping approx. 6 mm

• torque max 0.8 Nm

To reduce the total starting current, in case of simulta-

neous activation of two or more output channels, it is pre-

ferable to enable the delayed start function during confi-

guration via the ETS; in this case, each output channel

is activated with a delay time after the previous channel.

The delay is adjustable in the range 5 ... 40 s and is equal

for all channels.

Warming! The number of electrothermal actuators

that can be connected in parallel to each output is

limited by the rated current and the starting current

of the device. Carefully check the information on

the technical documentation of the manufacturer of

actuators.
