3.7 Mounting of device
Max. torque for fixing: 0.5 Nm/M4
The LED Driver is designed for a life-time stated above under reference
conditions and with a failure probability of less than 10 %.
2. Thermal details and life-time
2.1 Expected life-time
3. Installation / wiring
3.1 Circuit diagram
3.2 Wiring type and cross section
The wiring can be stranded wires with ferrules or rigid wires with a cross
section of 0.5 – 1.5 mm².
Strip 8.5 – 9.5 mm of insulation from the cables to ensure perfect operation
of the push-wire terminals (WAGO 250).

3.3 Release of the wiring
Press down the “push button” and remove the cable from front.
3.4 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.).
3.5 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)
• 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.
For Class II application, protection earth is no need to be connected, below 2
scenarios should be considered:
• If the LED Driver housing is screw on a metal part inside the luminaires,
both LED Driver and LED module must be insulated.
• If the LED Driver housing is screw on a plastic part inside the luminaires,
the LED module need to be insulated.
3.6 Replace LED module
1. Mains off
2. Remove LED module
3. Wait for 30 seconds
4. Connect LED module again
Hot plug-in or output switching of LEDs is not permitted and may cause
a very high current to the LEDs.

Product description
The relation of tc to ta temperature depends also on the luminaire design.
If the measured tc temperature is approx. 5 K below tc max., ta temperature
should be checked and eventually critical
components (e.g. ELCAP) measured. Detailed information on request.
