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

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.
