The Residual Current Device(RCD) is basicallyprovided
toprotectthe userfromlethalelectricshock. The RCD will
turnoff (trip) ifthe current flowing inthe liveconductor
doesnotfullyreturndownthe neutralconductor, i.e. some
current ispassing through apersondowntoearthor
throughafaultyappliance.
Toensurethe RCD isworkingcorrectly, thetest button
should beoperatedeachtimethe vehicleisconnectedto
the mainssupply(seesection 2.4)
The MiniatureCircuit Breakers(MCB’s) operatein asimilar
waytotraditional fusesand areprovidedtoprotectthe
wiring installation fromoverloador short circuit. If an
overload occurstheMCB will switchoffthe supply. Ifthis
occursyou shouldinvestigatethe causeofthe fault before
switchingtheMCB back on.
The following table showsthe rating and circuitallocation forthe three MCB’s

3 10 Amps Black(Blue forwaterheater) Fridge /WaterHeater/
12vCharger(internallyconnected)
3.2BatteryCharger
The EC400 / EC450 systemincorporatesan intelligent three-stage batterycharger/ powerconverter.
During stage 1 the batteryvoltage isincreased graduallywhile the current islimited to startthe
charging process and protect the battery. At stage 2 the voltage risesto 14.4Vtodeliverthe bulk
charge tothebattery.When thebatteryischarged, the voltage isdecreased at stage 3 to 13.6Vto
delivera float charge to maintainthe batteryinthe fullycharged state. The chargercan be left
switched on continuouslyasrequired.
The batterycharger/ powerconverteralsoprovidespowerto the leisure equipment when the mains
supplyisconnected. Thismodule suppliesDC totheleisure equipment up to amaximumof25 Amps
(300 Watts), therefore the available powerisdistributed between the leisureload and the battery,with
the leisure load taking priorityasperthe following example:

leisure andvehiclebatteriesand automaticallyadjustsand directsthe chargerpower(and solarpower
ifa solarpanelisinstalled)to maintain the leisureandvehiclebatteriesat an optimallevel.
3.4LeisureBattery
A)Type / Selection
Foroptimumperformance and safetyitisessentialthat onlya proprietarybrand LEISUREbatteryis
used with a typicalcapacityof75 to 120Ah(Ampere / hours). AnormalcarbatteryisNOTsuitable.
Thisbatteryshouldalwaysbe connected when the systemisin use.
The PSUisconfigured to workwith standard lead acid leisure batteries, and in most casesisalso
compatiblewiththelatest rangeofAbsorbed Glass Matt (AGM)batteries. Beforefittingnon-standard
batteriespleasecheckthat the charging profile described in 3.2 issuitableforthe type ofbatteryby
referring to the batterydocumentation orbatterymanufacturer.
Some vehicleinstallationscan caterfortwoleisure batteriesconnected in parallel. In these casesit is
recommended that two identicalbatteriesare used.
The batteryfeed isfitted with an inline fuse between the batteryandtheelectricalharness, andis
usuallylocated immediatelyoutside the batterycompartment orwithin 500mmofthe battery. The
maximumrating ofthisfuse is20Aperbattery.Ifa singlebatteryisfitted to amotorhome, thisfuse
maybe increased to40A,howeveriftwobatteriesare fitted eachbatteryshouldbe fused at a
maximumof20A.
B)Installation & Removal
Alwaysdisconnect the 230vmainssupplyandturn thePSU green chargerswitchto the off position
(buttonout)before removing orinstalling the battery.
When connecting the battery,ensure that the correct polarityisobserved (blackis negative[-] and red
ispositive [+])and that the terminalsare securelyfastened. Crocodile clipsmustnot be used.
WARNING
Explosive gasesmaybe present at the battery.Takecare to prevent flamesand sparks in thevicinity
ofthe batteryand do not smoke.
C)Operation / Servicing
Undernormalcircumstancesit shouldnot be necessaryto remove thebatteryotherthanforroutine
inspection ofthe terminalsand “toppingup”ofthe batteryfluidwhere applicable. Please see
instructionssupplied withthe battery.
Note: Do not overdischarge thebattery.One ofthe most common causesofbatteryfailureiswhen
the batteryisdischarged below therecommended levelofapproximately10v. Discharginga battery
belowthisfigure can causepermanent damage to one ormore ofthe cellswithin the battery.
To preventoverdischarge, the EC400-450 systemincorporatesa batteryprotectcircuit that warnsthe
users and thendisconnectsthe batterieswhen theyfall belowset values.
