External fuse for DC operation
The internal fuse of an LED Driver is not rated for DC operation. Because of this, an additional external fuse must be used if an LED
Driver is operated on a DC network.
Proceed as follows:
For LED Drivers with a power of 25-150 watts the following values are recommended:
Tridonic recommends the following external fuse:
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 temperature sensor.
_
Depending on the design of the luminaire it may be possible to improve the radio interference properties by earthing the
device at the earth connection.
_
The LED Driver has no inverse-polarity protection on the secondary side. Wrong polarity can damage LED modules with no
inverse-polarity protection.
_
Use solid wire or stranded wire with the correct cross-section
_
Strip off correct length of insulation; you may need to twist the tool slightly
_
If stranded wire is used: push onto the terminal from above to be able to insert the wire
_
Insert the bare end into the terminal
_
Push onto the terminal from above to release the wire
_
Pull out the wire at the front
_
Connect the external fuse to the line labeled "+" which is between the DC power supply and the input terminal of the LED
Driver
_
Only use an external fuse with suitable parameters.
