The bus cable can be extended with a two-wire cable (bell wire). The cable carries
low voltage and must not run together in a cable conduit with cables carrying a
higher voltage than 50 V (please pay attention to the valid local regulations such as
VDE regulations for Germany). The cross section must be at least 0.5 mm
2 and the
cable can be extended up to 50 m in the case of a single connection.

The SD3 / SDFK Smart Display can be operated in parallel with a controller and
additional modules via a bus line.
Connect the connection cable with stripped ends and any polarity to the VBus
® -ter-
minals at the rear side of the SD3 / SDFK.
Pass cable through strain relief.
During commissioning, the SD3 / SDFK Smart Display carries out an initialising
phase. After this test the following indications are shown:
• SD3 / SDFK in the upper display
• Software version in the display in the middle
• Date of software version (YYMMDD) in the lower display
Afterwards, the SD3 / SDFK Smart Displays receives data packets from the control-
ler. The progress is indicated in the lower display.
Afterwards, the SD3 / SDFK Smart Displays is ready for normal operation.
Note
If several SD3 / SDFK Smart Displays are used simultaneously, a VBus
®
Repeater will be required for amplifying the VBus
