2.3 Basic function principles
Coupling to price-sensitive actuators in a controller system is a challenge for a universal gateway. A
building's illumination is typically implemented through a large number of devices. The price of a lamp, and
therefore of the connection to a control system, is thus of great significance.
DALI
The Digital Addressable Lighting Interface (DALI) is a simple bus system for building automation that
transmits the signals for the digital operation of lighting devices. The lamp, sensor, button and switching
elements are wired in parallel, and are linked through the controller. Other actuators, such as heating control
valves or the motors for operating blinds are increasingly being put under digital control.
DALI offers the following advantages:
• an inexpensive interface with simple installation

Product overview
KL6811 11Version: 2.0.0
• fully digital switching of lamps and similar equipment.
• all main manufacturers of ballasts support DALI
The KL6811 DALI Master Terminal from Beckhoff closes the gap between lighting controller and lamp and
enables the connection of up to 64 DALI devices (DALI slaves). The KL6811 is integrated into the
BECKHOFF Bus Terminal system as a normal Bus Terminal and is therefore fieldbus-independent. The
higher-level Bus Coupler transfers the data from the DALI master terminal to the controller. The DALI power
supply unit integrated in the KL6811 supplies the DALI bus. No further components are required for the
operation of the DALI line.
During the start-up phase, the KL6811 searches for connected DALI slaves and supports the user during
commissioning of the system. The KS2000 [}21] configuration software can be used to parameterize the
DALI master terminal from a PC. The parameterization takes place via the fieldbus or via a RS232 interface,
which are connected to the configuration interface of the higher-level Bus Coupler.
DSI
The KL6811 can also be operated as a DSI master. The Digital Serial interface (DSI) is an even simpler bus
system for lighting control. The DSI master sends digital light intensity values serially to the DSI slaves. The
brightness of the slaves can be set between 1% and 100%. The assignment of the brightness to the control
values is logarithmic, so that a human observer sees a uniform increase in brightness when the control
values are increased linearly. The slaves can be switched to dark by setting the control value to 0, without
having to switch off the mains voltage.

3 Mounting and wiring
3.1 Installation on mounting rails
WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or
wiring of the bus terminals!
Assembly
Fig.3: Attaching on mounting rail
The bus coupler and bus terminals are attached to commercially available 35mm mounting rails (DIN rails
according to EN60715) by applying slight pressure:
1. First attach the fieldbus coupler to the mounting rail.
2. The bus terminals are now attached on the right-hand side of the fieldbus coupler. Join the compo-
nents with tongue and groove and push the terminals against the mounting rail, until the lock clicks
onto the mounting rail.
If the terminals are clipped onto the mounting rail first and then pushed together without tongue and
groove, the connection will not be operational! When correctly assembled, no significant gap should
be visible between the housings.
Fixing of mounting rails
The locking mechanism of the terminals and couplers extends to the profile of the mounting rail. At
the installation, the locking mechanism of the components must not come into conflict with the fixing
bolts of the mounting rail. To mount the mounting rails with a height of 7.5mm under the terminals
and couplers, you should use flat mounting connections (e.g. countersunk screws or blind rivets).

Mounting and wiring
KL6811 13Version: 2.0.0
Disassembly
Fig.4: Disassembling of terminal
Each terminal is secured by a lock on the mounting rail, which must be released for disassembly:
1. Pull the terminal by its orange-colored lugs approximately 1cm away from the mounting rail. In doing
so for this terminal the mounting rail lock is released automatically and you can pull the terminal out of
the bus terminal block easily without excessive force.
2. Grasp the released terminal with thumb and index finger simultaneous at the upper and lower grooved
housing surfaces and pull the terminal out of the bus terminal block.
Connections within a bus terminal block
The electric connections between the Bus Coupler and the Bus Terminals are automatically realized by
joining the components:
• The six spring contacts of the K-Bus/E-Bus deal with the transfer of the data and the supply of the Bus
Terminal electronics.
• The power contacts deal with the supply for the field electronics and thus represent a supply rail within
the bus terminal block. The power contacts are supplied via terminals on the Bus Coupler (up to 24V)
or for higher voltages via power feed terminals.
Power Contacts
During the design of a bus terminal block, the pin assignment of the individual Bus Terminals must
be taken account of, since some types (e.g. analog Bus Terminals or digital 4-channel Bus Termi-
nals) do not or not fully loop through the power contacts. Power Feed Terminals (KL91xx, KL92xx
or EL91xx, EL92xx) interrupt the power contacts and thus represent the start of a new supply rail.
PE power contact
The power contact labeled PE can be used as a protective earth. For safety reasons this contact mates first
when plugging together, and can ground short-circuit currents of up to 125A.

Mounting and wiring
KL681114 Version: 2.0.0
Fig.5: Power contact on left side
NOTE
Possible damage of the device
Note that, for reasons of electromagnetic compatibility, the PE contacts are capacitatively coupled to the
mounting rail. This may lead to incorrect results during insulation testing or to damage on the terminal (e.g.
disruptive discharge to the PE line during insulation testing of a consumer with a nominal voltage of 230V).
For insulation testing, disconnect the PE supply line at the Bus Coupler or the Power Feed Terminal! In or-
der to decouple further feed points for testing, these Power Feed Terminals can be released and pulled at
least 10mm from the group of terminals.
WARNING
Risk of electric shock!
The PE power contact must not be used for other potentials!
3.2 Connection system
WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or
wiring of the Bus Terminals!
Overview
The Bus Terminal system offers different connection options for optimum adaptation to the respective
application:
• The terminals of KLxxxx and ELxxxx series with standard wiring include electronics and connection
level in a single enclosure.
• The terminals of KSxxxx and ESxxxx series feature a pluggable connection level and enable steady
wiring while replacing.
• The High Density Terminals (HD Terminals) include electronics and connection level in a single
enclosure and have advanced packaging density.

Mounting and wiring
KL6811 15Version: 2.0.0
Standard wiring
Fig.6: Standard wiring
The terminals of KLxxxx and ELxxxx series have been tried and tested for years.
They feature integrated screwless spring force technology for fast and simple assembly.
Pluggable wiring
Fig.7: Pluggable wiring
The terminals of KSxxxx and ESxxxx series feature a pluggable connection level.
The assembly and wiring procedure for the KS series is the same as for the KLxxxx and ELxxxx series.
The KS/ES series terminals enable the complete wiring to be removed as a plug connector from the top of
the housing for servicing.
The lower section can be removed from the terminal block by pulling the unlocking tab.
Insert the new component and plug in the connector with the wiring. This reduces the installation time and
eliminates the risk of wires being mixed up.
The familiar dimensions of the terminal only had to be changed slightly. The new connector adds about 3
mm. The maximum height of the terminal remains unchanged.
A tab for strain relief of the cable simplifies assembly in many applications and prevents tangling of individual
connection wires when the connector is removed.
Conductor cross sections between 0.08mm2 and 2.5mm2 can continue to be used with the proven spring
force technology.
The overview and nomenclature of the product names for KSxxxx and ESxxxx series has been retained as
known from KLxxxx and ELxxxx series.
High Density Terminals (HD Terminals)
Fig.8: High Density Terminals
The Bus Terminals from these series with 16 connection points are distinguished by a particularly compact
design, as the packaging density is twice as large as that of the standard 12mm Bus Terminals. Massive
conductors and conductors with a wire end sleeve can be inserted directly into the spring loaded terminal
point without tools.

Fig.9: Mounting a cable on a terminal connection
Up to eight connections enable the connection of solid or finely stranded cables to the Bus Terminals. The
terminals are implemented in spring force technology. Connect the cables as follows:
1. Open a spring-loaded terminal by slightly pushing with a screwdriver or a rod into the square opening
above the terminal.
2. The wire can now be inserted into the round terminal opening without any force.
3. The terminal closes automatically when the pressure is released, holding the wire securely and per-
manently.
