This device is a product of the KNX/EIB instabus-KNX/
EIB system and complies with KNX directives. Detailed
technical knowledge obtained in KNX/EIB training cour-
ses is a prerequisite to proper understanding.The func-
tionality of this device depends on the software.
Detailed information on loadable software and attainab-
le functionality as well as the software itself can be ob-
tained from the manufacturer's product database.
Planning, installation and commissioning of the unit is
effected by means of KNX-certified software. An up-
dated version of the product database and the technical
descriptions are available in the Internet at www.mer-
ten.de.
The coupler connects two instabus KNX/EIB data lines
and ensures the electrical separation of these lines
from one another. The definite functions of the device
are defined by addressing and parameterization.
Line coupler LK:
Physical address X.0.0
Connection of a main line (HL) with an area line (BL). Al-
ternatively with or without filter function. The coupler
belongs logically to the subordinate line.
Area coupler BK:
Physical address X.0.0
Connection of a main line (HL) with an area line (BL). Al-
ternatively with or without filter function. The coupler
belongs logically to the subordinate line.
Amplifier V:
Physical address X.Y.Z
Handling and repetition of telegrams on a line, no filter
function. Division of a line into max. 4 independent line
segments => max. 3 line amplifiers connected in paral-
lel per line (FIG. C). Each line segment requires a sepa-
rate power supply (SV) including a choke (DR).

Use as area and line coupler (BK and LK)
Use as line coupler LK and amplifier V
(TLN = bus subscriber, DR = choke, SV = instabus KNX/
EIB power supply)
Each line requires a separate power supply.

Function of diagnosis LED ("DIAG") red
LED off:
Telegrams are filtered or blocked
(both directions)
LED on:
Telegrams are retransmitted
without being filtered (at least one
direction)
LED flashing:
error detected (as per error flags
in device)

1
The device is snap-fastened on the DIN rail until the
latch is heard to engage, with the connecting termi-
nals pointing downwards
2
The superordinate line is connected with the left-
hand terminal (terminal "HL"). This terminal sup-
plies power to the device electronics so that it is
possible to report a bus voltage failure of the sub-
ordinate via the superordinate line.
3
The subordinate line is connected to the right-hand
terminal (terminal "UL").

Removal info:
Do not lever out the connecting
termianal from below. Risk of shorting the bus
voltage which is not available during the short-cir-
cuit.
¼
Risk of fatal injury from electrical current.
All work carried out on the device may only be per-
formed by skilled electricians.
The country-specific regulations and the valid KNX
guidelines must be followed.
1
Load the physical address into the push-button from
the ETS via the KNX bus.
2
Complete the required configuration settings in the
ETS, and transfer the configuration via EIB into the
coupler.
