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.
