LED Driver
Constant voltage
3.5 Hot plug-in
Hot plug-in is not supported due to residual output voltage of > 0 V.
If a LED load is connected the device has to be restarted before the output will
be activated again.
This can be done via mains reset or via interface (DALI, DSI, switchDIM).
3.6 Earth connection
The earth connection is conducted as protection earth (PE). The LED Driver
can be earthed via earth terminal. If the LED Driver will be earthed,
protection earth (PE) has to be used. There is no earth connection required
for the functionality of the LED Driver. Earth connection is recommended to
improve following
behaviour:
• Electromagnetic interferences (EMI)
• LED glowing at standby
• Transmission of mains transients to the LED output
In general it is recommended to earth the LED Driver if the LED module is
mounted on earthed luminaire parts respectively heat sinks and thereby
representing a high capacity against earth.
3.3 Loose wiring
Release of the wiring
Press down the “push button” and remove the cable from front.
Mains supply wires
Secondary wires (LED module)
3.4 Wiring guidelines
• Run the secondary lines separately from the mains connections and lines
to achieve good EMC performance.
• The max. secondary cable (LED module) length is 2 m (4 m circuit).
• For good EMC performance, keep the LED wiring as short as possible.
• To comply with the EMC regulations run the secondary wires
(LED module) in parallel.
• Secondary switching is not permitted.
• The LED Driver has no inverse-polarity protection on the secondary side.
Wrong polarity can damage LED modules with no inverse-polarity
protection.
• Wrong wiring of the LED Driver can lead to malfunction or irreparable
damage.
• To avoid the damage of the Driver, the wiring must be protected against
short circuits to earth (sharp edged metal parts, metal cable clips, louver,
etc.).
