Wiring guidellines
- The cables should be run separately from the mains connections and mains cables to
ensure good EMC conditions.
- The LED wiring should be kept as short as possible to ensure good EMC.
The max. secondary cable length is 2 m (4 m circuit), this applies for LED output as well
as for I-select 2.
- 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.
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,
ready2mains).
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.
