 When installing the equipment, it should ensure that the sum oftheleakage
currentoftheUPSandtheconnecteddevicesdoesnotexceed3.5mA. 
1-4 Operation
 DonotdisconnectthemainscableontheUPSsystemorthebuilding wiring
outlet(shockproofsocketoutlet)duringoperationssincethiswouldcancelthe
protectiveearthingoftheUPSsystemandofallconnectedloads. 
 The UPS system features its own, internal current source (batteries).TheUPS
outputsocketsoroutputterminalsblockmaybeelectricallyliveeveniftheUPS
systemisnotconnectedtothebuildingwiringoutlet. 
 InordertofullydisconnecttheUPSsystem,firstpresstheOFF/Enterbuttonto
disconnectthemains. 
 PreventnofluidsorotherforeignobjectsfrominsideoftheUPSsystem. 
1-5 Maintenance,serviceandfaults
 TheUPSsystemoperateswithhazardousvoltages.Repairsmaybecarried out
onlybyqualifiedmaintenancepersonnel. 
 Caution - risk of electric shock. Even after the unit is disconnected from the
mains (building wiring outlet), components inside the UPS system are still
connectedtothebatteryandelectricallyliveanddangerous. 
 Before carrying out any kind of service and/or maintenance, disconnect the
batteriesandverifythatnocurrentispresentandnohazardousvoltageexistsin
theterminalsofhighcapabilitycapacitorsuchasBUS-capacitors. 
 Only persons are adequately familiar with batteries and with the required
precautionary measures may replace batteries and supervise operations.
Unauthorizedpersonsmustbekeptwellawayfromthebatteries.
 Caution-riskofelectricshock.Thebatterycircuitisnotisolatedfromtheinput
voltage.Hazardousvoltagesmay occur betweenthe batteryterminals andthe
ground.Beforetouching,pleaseverifythatnovoltageispresent! 
 Batteriesmaycauseelectricshockandhaveahighshort-circuitcurrent.Please
take the precautionary measures specified below and any other measures
necessarywhenworkingwithbatteries: 
－removewristwatches,ringsandothermetalobjects 
－useonlytoolswithinsulatedgripsandhandles. 
 Whenchangingbatteries,installthesamenumberandsametypeofbatteries. 
 Donotattempttodisposeofbatteriesbyburningthem.Thiscouldcausebattery
explosion. 
 Donotopenordestroybatteries.Escapingelectrolytecancauseinjurytotheskin
andeyes.Itmaybetoxic. 
