NOTE
The functions of WAECO DC-Kit2/DC-Kit3/DC-Kit5 in conjunction with the
Dometic B2200 described in this manual relate to roof air conditioners with a
serial number higher than 802200001. In the case of Dometic B2200 roof air
conditioners with a lower serial number, the DC-Kit functions for the
Dometic B1600 are possible.
6 Technical description
During a journey, a light system generates a voltage of approx. 14 V which ensures that
the starter battery is recharged and the vehicle's electrical consumers are supplied.
Some caravans also have an electrical connection between the starter and additional
battery which is active when the vehicle engine is running. This cable is designed for
currents up to 20 A. When the air conditioner is in operation via the inverter, the current
taken from the 12 V supply can be up to 120 A. This would overload any standard con-
nection lead present between the starter and additional battery because the light system
is supposed to deliver a large proportion of the load current.
A remedy for this is an additional cable connection (for cable cross sections see table on
page 102) between the starter battery and additional battery which is switched on via the
power relay of the ECL-76/ECL-102/ECL-103 and switched off when the voltage is low.
