Some devices have two pairs of output cables that may also have the same color but
of different section:
The pair of cables of larger section is the power output of the
charger,
which
must
be
connected
to
the
battery,
while
the
other
pair
consists of a dry contact of a NORMALLY OPEN relay
. Connecting one cable to
the battery voltage, the Normally Open contact, can be used to turn on a 12V lamp
(or LED) when the main line is connected.
If the pair of cables with the larger section is BROWN-BLUE color, the
POSITIVE is the BROWN cable.
The cooling fan/fans are electronically controlled by the microcontroller which
decides the power and speed according to the conditions of the internal and
environment temperatures.
