2.Safety
DANGER!
Do not wear metallic objects such as watches, rings, bracelets. May cause burns in the
event of a short-circuit between the battery poles.
DANGER!
Always assume the presence of 230 VAC 50 Hz mains power even in the event of a
mains power failure.
DANGER!
The batteries are sealed units and should not be opened. If battery acid comes into
contact with the eyes wash immediately and thoroughly with water. Seek medical help
immediately. Do not smoke, create sparks or use naked ames near the batteries.
WARNING!
Be careful not to short circuit the battery cables. Before making the connections, ensure
the cables are in good condition.
Strictlyfollowtheinstructionscontainedinthismanual.
WARNING!
For connection to the mains electrical supply it is imperative that the Delta HLA is
connected to a dedicated power supply and not via a ring main.

4.5.1 Connecting an automatic pump to the Delta Battery Backup
Shouldyouneedtoconnecta
manualpumptotheDeltaBattery
Backup,usetheAL/AN(Aux
Load)terminalsinsteadofthe
UL/UN(DirectLoad)terminals.
Thelevelcontrol(oat,pressure
switchetc)whichcontrolsthe
pumpshouldconnecttotheAux
Contactterminals.
WhentheAuxContactterminals
areclosedbytheactivatedlevel
control,avoltageisapplied
acrosstheAL/ANterminalsthus
poweringthepump.Whenthe
levelcontroldeactivates,theAux
Contactisopenedandthepump
isde-powered.
AllstandardDeltapackaged
pumpingstationsthatare
compatiblewiththeDeltaBattery
Backupfeatureautomaticpumps
(pumpswhichcomewithaoat
alreadyattached).
• DeltaV3Pump
• DeltaV4Pump
• DeltaV6Pump
• DeltaFoulV3Pump(Automatic)
TheseconnecttotheUL/UN
(DirectLoad)terminals.
Inoperation,therewillalwaysbe
avoltageacrosstheseterminals.
Thepump’sintegraloatswitchwill
activatethepump.

5.1 Door-locking isolator switch
Thesystemisprotectedbyadoor-lockingisolatorswitch.ToopenthedoorItmustbeintheOFFposition.
5.2 Switching on the rst time
Afterinstallation,closethedoorandturntheisolatortotheONposition.
Assumingthereismainspower,thedisplaywillread“NETWORKPRESENCE”.
5.Operation
WhiletheDeltaBatteryBackupisconnectedtomainspoweritwillchargeandmaintainthebattery(s).After15minutes,itwill
carryouttherstreadingofthebatteryvoltageanddisplayit..
Thebatteryvoltagereadingisupdatedeverytwohours.
5.3 Network power failure
IntheeventofnetworkpowerfailuretheDeltaBatteryBackupautomaticallydisconnectsthebatterychargerandswitchesto
poweringthepumpfromthebatteryviatheinverter.Thedisplaywillread“NONETWORKPRESENCE“.
Thesystemcontinuestopowerthepumpuntiltheinputvoltagefromthebatterydropsbelow10VDC,afterwhichthesystemis
placedinSTANDBY.

5.4 Test function
Inthe“NETWORKPRESENCE”state,pressingthe“TEST”buttonwillcarryoutthefollowingoperations:
• disconnectsofthebatterycharger
• switchesformmainspowertobatterypowerviatheinverter
• powerstheAuxiliaryLoadterminal
Ifafter30secondsnoanomalieshavebeendetectedintheconnectedloadorintheinverter,thedevicewillreturntonormal
functionwithoutanycommunication.
Ifananomalyisdetected,theappliancewillmake5resetattemptsand,ifallattemptsfail,thesystemwilltriggeranAnomaly
Loadalarm(K6relay)andthescreenwilldisplay“ANOMALYLOAD”.
ToresetthesystempresstheRESETbutton.
WARNING!
The unit must be tested with both mains power connected and disconnected.
