28000684 Wiring

28000684 Wiring type and cross section

Solid wire with a cross section of 0.5 – 1.5 mm². Strip 8 – 9 mm of insulation from the cables to ensure perfect operation of terminals.

28000684 Wiring guidelines

• 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).
• 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.).

Earth connection

The earth connection is conducted as protection earth (PE). 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)
• 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.
