1Introduction
Thissection ofthe handbookwillguide youthrough the operation ofthe electricalsystem. All details
are correct at the time ofgoing to press. Pleasealso see the online version whichwillinclude anylater
updatesoramendments.
Furthertechnicaldetailsare contained in section 3 orin thesupporting technicalmanualavailablefrom
www.sargentltd.co.uk
Forthe safe operationofall electricalequipment within yourmotorhome it isimportant that you read
and fullyunderstand these instructions. If you are unsure ofanypoint please contactyourdealer/
distributorforadvicebeforeuse.
The systemhasa numberofkeycomponentsthat youwillneedto be familiarwithbefore attempting to
use thesystem, these are:
·The EC700 PowerSupplyUnit (PSU)-a combined mainsconsumerunitand 12Vcontroller
located in the bed boxorupperlocker.
·The EC700 ControlPanel(CP)-a remotelylocated usercontrolpanelused to turn circuits
on and off and to displaybattery, watertankand othersysteminformation. Thispaneluses
simple straightforward controlsandreliabledata communication to the PSU.
·The PX300 Intelligent Batterycharger300W. -Aseparate, aircooled 300Watt multi-stage
powerconverterunit that chargesthe batteriesand provides12VDC power.
·The EM40Vehicle Interface Unit -Thissmall unitislocated at floorlevelbehind the drivers’
seat. The unithousesfusesforthe fridge, vehiclebattery, radioand othersystems. It also
providesconnectionsforthe optionaltowbarharness.
2Using theSystem

2.2Activating theSystem
The EC700 systemhasa shutdown feature that canbe used when the vehicleisin storage. This
allowsthe leisureelectronicsto be turned off when not required tosave batterypower. When in theoff
state the alarmand tracking systemsuppliesare stillactive, all othersuppliesareturned off.
Before using the systemplease ensure the systemshutdown switchisin the on position (button in)the

3System Technical Information
The following section providesfurthertechnicalinformation relating to the electricalsystem. You can
also access thesupportingtechnicalmanualfrom www.sargentltd.co.uk
3.1Residual CurrentDevice &MiniatureCircuitBreakers
The Residual Current Device(RCD) is
basicallyprovided toprotecttheuser
fromlethal electricshock. TheRCD will
turnoff (trip) ifthe current flowing inthe
liveconductordoesnot fullyreturndown

is passingthrough apersondownto
earthor through afaultyappliance.
Toensurethe RCD isworkingcorrectly,
the test buttonshouldbeoperated each
timethe vehicle isconnected tothe
mainssupply(seesection 2.3)
The MiniatureCircuit Breakers(MCB’s)
operateinasimilar waytotraditional
fusesandareprovided toprotect the
wiring installation fromoverloador short
circuit. If anoverload occursthe MCB
will switchoffthe supply. Ifthisoccurs
you should investigatethecauseofthe

3.2Generator Usage
Caution should be used before connecting a generatorto yourmotorhome.
WARNING
Neverstart orstopthegeneratorwhile electricalloadsare connectedand switched on.Start the engine,
let it stabiliseand then connect the electricalload.When stopping the generator,disconnect theelectrical
load and let enginestabilise before switching off.
Whilstsomegenerators useelectronicinvertertechnology,others useamorebasicprincipletogenerate
the 230Vsupply.Preferenceshouldbeto chooseageneratorwhichproducesaconsistentsinusoidal
wave formwith accurate voltage control.
The ReversePolaritywarning lighton the PSUmayilluminate when usingaGenerator.Thisisanormal
side effectwhen usingsometypesofgenerator.Instead ofconnectingtheneutralconductorto earth,
somegenerators centretaptheearthconnection making bothneutraland liveconductors 110Vabove

B)Installation & Removal
Alwaysdisconnectthe230Vmainssupplyand turnthe PSUgreenchargerswitchto the off position
(buttonout)before removing orinstalling the battery.
When connectingthe battery,ensurethatthecorrectpolarityisobserved(blackis negative[-]andred
