28004374 Wiring

28004374 Wiring type and cross section

For wiring use stranded wire with ferrules. For perfect function of the terminals the strip length should be 9–10 mm for
the terminal. The maximum secondary cable length is 2 m. The LED wiring should be kept as short as possible to ensure good EMC

28004374 Wiring guidelines

All connections must be kept as short as possible to ensure good EMI behaviour. Mains leads should be kept apart from LED driver and other leads (ideally 5 – 10 cm distance)
Max. length of output wires is 2 m. Incorrect wiring can damage LED modules. 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.).

Hot plug-in

Hot plug-in or secondary switching of LEDs is not permitted and may cause a very high LED output current

Earth connection

The earth connection is conducted as protection earth (PE). The LED driver can be earthed via 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 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.

Installation instructions

The switching of LEDs on secondary side is permitted.
The functioning of the LC in combination with dimming devices (e.g. PWM) cannot be guaranteed and has to be checked individually before using in combination.
