Mounting

The device has degree of protection IP20, and is therefo-

re suitable for use in dry interior rooms. The device has to

be installed with the metallic support and the screws (in-

cluded in the delivery) on a wall box with 60 mm distance

between fixing holes. Previously connect the bus terminal

block to the bus cable (see: "Connection of the KNX bus

line") and enter it in its slot on the rear of the device. At

this point it is recommended to carry out the commissio-

ning of the device (see "Commissioning") or at least the

download of the physical address. Eventually snap the

cover with lens on the device.

Connection of the KNX bus line

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

minal block (8) 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! 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.

KNX

bus

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.

Configuration and commissioning

Configuration and commissioning of the device require

the use of the ETS

(Engineering Tool Software) program

V3 or later releases. These activities must be carried out

according to the design of the building automation system

done by a qualified planner.

Note. The configuration and commissioning of KNX

devices require specialized skills. To acquire these

skills, you should attend the workshops at KNX cer-

tified training centers.

Configuration

For the configuration of the device parameters the corre-

sponding application program or the whole ekinex

duct database must be loaded in the ETS program. For

detailed information on configuration options, refer to the

application manual of the device available on the website

www.ekinex.com.

Commissioning

For commissioning the device the following activities are

required:

• make the electrical connections as described above;

• turn on the bus power supply;

• switch the device operation to the programming mode

by pressing the programming pushbutton located on

the front side of the housing. In this mode of operation,

the programming LED is turned on;

• download into the device the physical address and the

configuration with the ETS

At the end of the download the operation of the device

automatically returns to normal mode; in this mode the

programming LED is turned off. Now the bus device is

programmed and ready for use.

Note. After the connection to the KNX bus it is ne-

cessary to wait approximately a minute before the

sensore reaches a stable functioning condition.
