28000656 Wiring guidelines

• Run the secondary lines separately from the mains connections and lines to achieve good EMC performance.

• The max. secondary cable length is 2 m (4 m circuit), this applies for LED output as well as for I-SELECT 2.

• For good EMC performance, keep the LED wiring as short as possible.

• 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.).

28000656 Earth connection

The earth connection is conducted as protection earth (PE). The LED Driver can be earthed via earth terminal or metal housing. 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 stand-by
• Transmission of mains transients to the LED output
