1. Safety
Please readcarefullythe following usermanual and the safety
instructions before installing the unit orusing theunit!
1.1 Installation
Condensationmayoccurifthe UPSismoveddirectly froma
coldto awarmenvironment.TheUPS mustbe absolutelydry
beforebeing installed.Pleaseallowanacclimatization time of
atleast twohours.
Donot install theUPS nearwaterorindampenvironment.
Do not install theUPS whereitwould beexposedtodirect
sunlightor near heat.
Donotblockventilationopenings inthe UPS’s housing.
Do notconnectappliancesor items ofequipment which would
overload theUPS (e.g.laserprinters,etc) to theUPS output.
Place cablesinsuchaway that no onecan step onortripover
them.
UPShasprovidedearthedterminal, in thefinal installed
system configuration,equipotentialearth bonding tothe
externalUPS battery cabinets.
An integralsingle emergency switchingdevice whichprevents
furthersupply totheloadbytheUPS inany mode of operation
should be provided inthe buildingwiringinstallation.

An appropriate disconnectdeviceasshort-circuitbackup
protectionshould beprovidedinthebuildingwiring
installation.
Forthree-phaseequipmentconnectiontoan ITpowersystem,
afour-poledevicewhich disconnectall phaseconductors and
the neutralconductorshouldbeprovidedin thebuildingwiring
installation.
This is permanentlyconnectedequipment, it mustbe installed
by qualifiedmaintenance personnel.
Earthconnectionessential beforeconnectingto thebuilding
wiringterminal.
1.2 Operation
Donotdisconnecttheearth conductorcableontheUPSor the
buildingwiringterminalsinanytimesincethis wouldcancel
the protectiveearthingof theUPS system andof allconnected
loads.
The UPSoutput terminal block may beelectricallylived even if
the UPS system is not connected to the building wiring
terminal.
Inorder to fullydisconnecttheUPS, turntheM1/M2/N input
breakerinthe“OFF”position ( for tower 3/110k-20k), turn the
R/S/T/N input switchinthe“OFF” position (fortower 3/1
10K-31Cmodel), then disconnect the mainslead.
Ensurethat noliquidorotherforeign objectscanenter the
UPS.

1.3 Maintenance, servicing and faults
The UPS operateswith hazardousvoltages.Repairsshouldbe
carriedout onlyby qualified maintenancepersonnel.
Caution-riskof electricshock.Evenaftertheunitis
disconnectedfrom the mainspower supply(building wiring
terminal), componentsinsidethe UPSarestillconnectedtothe
batterywhich are potentially dangerous.
Beforecarryingout any kind of serviceand/ormaintenance,
pleasedisconnectthe batteries.Verifythatnocurrentis
present and nohazardousvoltage existsinthecapacitoror
BUS capacitorterminals.
Batteries mustbereplaced onlyby qualified personnel.
Caution-riskof electric shock.Thebatterycircuitisnot
isolated from theinputvoltage. Hazardousvoltages mayoccur
betweenthebattery terminalsand theground.Verifythat no
voltageispresent before servicing!
Batterieshaveahighshort-circuit currentandposeariskof
shock. Takeall precautionarymeasuresspecifiedbelowand
any othermeasuresnecessarywhen working withbatteries:
removeall jewellery,wristwatches, rings and other metal
objects
use only tools withinsulated grips and handles.
Whenchangingbatteries,replacewith thesamequantity and
the same typeofbatteries.

4
Donotattempttodisposeofbatteriesby burningthem.It
couldcauseexplosion.
Donot openor destroybatteries.Effluentelectrolytecan cause
injury to the skin andeyes. It maybetoxic.
Pleasereplacethefuse onlyby afuseofthe sametypeand of
the same amperage inordertoavoidfire hazards.
DonotdismantletheUPS,except thequalifiedmaintenance
personnel.
1.4 Transport
Pleasetransport theUPSonlyintheoriginalpackaging(to
protect against shockand impact).
1.5 Storage
TheUPS mustbestockpiledintheroom whereitis ventilated
and dry.

electricians in accordance with applicable safety regulations!
4.1 Unpacking and Inspection
1. Moving to theinstallationsite
The tower3-phase seriesUPS has wheelsmaking it easytomove the
UPStothe installation site afterit hasbeenunpacked. However,if the
receiving area isfarfrom theinstallationsite,we recommendyou to
movetheUPS by usingapalletjackor alifter beforeyou startto
unpack the UPS.
2. Unpackingand inspection
1) At theinstallationsite,theutmostcareshallbe takenwhen
removingthepackaging in order to avoiddamagingthe equipment.
Checkallpackaging materialstoensurethat no itemsare missing.
The shippingpackage contains:
A UPS
A user manual
A communication cable

4.2 Input andOutput Power Cords andProtective
EarthGround Installation
1. Notesforinstallation
1) The UPSmustbe installed inalocationwithgoodventilation,far
awayfromwater,inflammable gas and corrosive agents.
2) Ensuretheairvents onthefront andrearoftheUPSare not
blocked.Allowat least 0.5mof spaceon each side.
3) Condensationtowaterdropsmay occurif theUPSisunpackedina
verylowtemperatureenvironment.Inthiscaseit isnecessaryto
wait untilthe UPSisfully driedinside outbeforeproceeding
installation and use. Otherwise there arehazards of electricshock.
4) Oncetheinstallation iscompleted, thesidemountingbrackets
（usedinshipping）shallbefixedbacktoensurethestabilityofthe
UPS enclosure. Ifimpossible,additional stability can beaddedby
anchoringthemountingbrackets tothe floorwith M8bolts.See Fig.

AWG Standardfor the UPS inputandoutput wirings.
Note: Do not usethewallreceptacleas the input power source
for theUPS,asits ratedcurrent islessthan theUPS’s
maximum inputcurrent. Otherwisethereceptacle may be
burnedanddestroyed.
4) Connecttheinputandoutput wirestothecorresponding input
and output terminals according to thefollowing diagram.
Note: youmustmakesurethat theinputandoutput wires and
the input and output terminals are connected tightly.
