Fitting Instructions
Installation:
The converter has to be connected to the 24V
contact socket of the trailer. The flap has to
lock the adapter to prevent the adapter from
releasing while driving. The connector of the
trailer also has to be fixed by the socket flap.
Malfunctions:
All converter junctions are electrically com-
pletely separated. They have no ground
connection of their own. Function tests
therefore have to be executed with a base
load of 5W. Multi meters then only show
values between 6 and 11V direct voltage.
This value is not correct because the con-
verter transmits the 24V voltage 'fragment-
ed' to the electric light bulbs and the meter
cannot show the absorbed of the light bulb.
A perfect meter should show exactly 25%
of the input power. Each line is protected
against short circuits and overheating. The
reset takes place automatically once the
cause of error has been removed.

IMPORTANT
RMS-LEDs are working with
internal series resistors or other
suitable techniques.
If reduction of light intensity occurs
in RMS pulse operation the reduc-
tion must remain within the light
intensity limits of the ECE regula-
tions (R6, R7, R23, R38).
If series resistor technology is
used, light intensity reduction of
20% to 35% must be expected.
The nominal light intensity of the
LED lamp unit for 12V operation is
mentioned in the manufacturer's
ECE approval.
