7. Installation of electrical devices
Operation via the tow vehicle
Whendriving,thebatteryofthetowvehicletakesoverthesupply
ofthe12Vsupplyifpin9ofthe13-pinsocketsystemonthetow
vehicle is connected.
Usethemainswitchonthecontrolpaneltoswitcho12Voperation
(whenthecaravanishookedtothecar)onlongerstopoversand
breakstoconservepowerinthecar'sbattery.
Whenrunningon12volts,therefrigeratoronlyfunctionsifthemotor
ofthetowvehicleisturnedon.Pins10and11ofthe13-pinsocket
system.
Alwaysswitchotheelectricconnectionbetweenthe
towvehicleandthecaravanbeforehookingthecara-
vanuptoalow-voltagesupply.
Ifoperationiscarriedoutviathetowvehicle,amaximum
of 2 electrical devices in the caravan can be switched
atthesametimeusingthecontrolpanelThisisnotthe
casewhena12vbatterysystem(selfsucientpackage)
is installed.
Thischeckshouldbecarriedoutatleastonceamonthtoensurethat
theresidualcurrentdevicefunctionsperfectlyincasethereshouldbe
a fault in the current.
WhentheFIswitchhasbeenswitchedo(evenwhen
testing)thecustomisedsettingsinallmains-operated
devicesarelostandthedefaultsettingsmadebythe
manufacturerwillapplyagain.
Devicesthatcauseittotripwheninuseshowthatthereisafault;they
mustbecheckedand/orrepairedbyanelectricalengineeringspecialist.
Iftheautomaticcircuitbreakerhasgoneo(otherthaniftheTest
functionhasbeenused)youmustwaitashortwhilebeforeswit-
ching it on again.
-Iftheautomaticcircuitbreakerremainsactive,therewasonlyan
overload.
-Iftheautomaticcircuitbreakergoesoabruptlyagain,thereis
either a short circuit or an earth fault.
Switchingitbackonagainandagainwilldonogood.
Theautomatic circuitbreakeralso goeso when the
rockerswitchisheldrmlyinplace.
