Operating instructions
1 Safety instructions
Electrical equipment may only be installed and fitted by electrically skilled persons.
Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.
Danger of electric shock. Device is not suitable for disconnection from supply voltage.
Danger of electric shock on the SELV/PELV installation. Do not connect loads for mains
voltage and SELV/PELV together on a single switch actuator.
Do not connect any three-phase motors. Device can be damaged.
Do not use the current detection and load monitoring functions for safety-related
applications e.g. overload detection.
For the outputs, use circuit breakers for the respective rated current. Device can be
damaged.
These instructions are an integral part of the product, and must remain with the end
customer.

3 Function
System information
This device is a product of the KNX system and complies with the KNX directives. Detailed
technical knowledge obtained in KNX training courses is a prerequisite to proper
understanding.
The function of this device depends upon the software. Detailed information on loadable
software and attainable functionality as well as the software itself can be obtained from the
manufacturer´s product database.
Planning, installation and commissioning of the device are carried out with the aid of KNX-
certified software. Full functionality with KNX commissioning software version ETS3.0d
onwards.
An updated version of the product database, technical descriptions and conversion programs
and other auxiliary programs are available on our Internet website.
Intended use
- Switching of 230 V AC or 24 V AC/DC electrical loads with floating contacts
- Mounting on DIN rail according to EN 60715 in distribution boxes
Product characteristics
- Manual switching of the relays is independent of the bus.
- Operation as NO or NC contacts
- Logic and restraint function
- Switching feedback (bus operation only)
- Switch position display
- Central switching function with collective feedback
- Disabling function for each channel
- Timing functions: switch-on delay and run-on time, staircase lighting timer with pre-warning
function
- Integration into light scenes
- Operating hours meter, configurable via bus
- Input monitoring for cyclical updating with safety circuit
- No additional power supply necessary
i When controlled by a central telegram the relay outputs of the actuator switch with a slight
time delay.
Additional characteristics of C load switch actuators
- Current detection: measurement of the load current for each output
- Monitoring of threshold values for load monitoring, e.g. for reporting load drop-out
- Switching of capacitive loads and the resulting high switch-on currents
4 Operation
Switching relay contacts manually
The status of the relay is reflected by the slide switches (1) on the front of the device (figure 1).
At the same time they can be used for manual operation of the relay outputs using a suitable
tool.
o Move slide switch to ON position.
Relay contact is closed, load is switched on.
o Move slide switch to OFF position.
Relay contact is open, load is switched off.
i The position of the slide switch immediately reflects the status of the relay, regardless of
whether the output is in NO or NC mode of operation.
i Manual switching of the relays is independent of the bus. Thus in case of manual switching
there will be no feedback via the bus.
i Outputs disabled via software can still be switched manually.

5 Information for electrically skilled persons
5.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the
corresponding circuit breakers. Cover up live parts in the working environment.
Fitting the device
Observe the temperature range. Ensure adequate cooling.
o Mount device on DIN rail. Output terminals must be at the top.
Figure 2
Connecting the device
Note permitted loads.
o Move relay to the OFF position.
o Connect device as shown in the connection example (figure 2).
o Connect bus line with bus connection terminal.
i Various external conductors can be connected.
i Devices for C loads use non-contact current sensors for current measurement. Magnetic
fields in the immediate vicinity may distort the current measurement. Lay forward and
return conductors next to each other as close as possible. Do not install in the immediate
vicinity any devices that generate magnetic fields, e.g. doorbell transformers, power
contactors, etc.
Installing the cover
It is necessary to install a cover to protect the bus connection against hazardous voltages in the
connection area.

Figure 3: Installing the cover
o Route the bus line towards the rear.
o Install cover on top of the bus terminal so that it snaps into place (figure 3).
Removing the cover
Figure 4: Removing the cover
o Press the cover to the side and pull it off (figure 4).
5.2 Commissioning
Load the address and the application software
o Switch on the bus voltage.
o Assign physical address.
o Load the application software into the device.
o Note the physical address on the device label.
