1. Brief introduction
1.1Systemandmodel description
TheOn-Line-Series isanuninterruptiblepower supply incorporating
double-converter technology.Itprovides perfect protectionspecifically for
strictload. Thedouble-converterprinciple eliminatesallmains power
disturbances. Arectifier converts the alternatingcurrentfrom the socket
outlet to direct current. Thisdirect current charges the batteriesand powers
the inverter.In the eventof powerfailure, the maintenance-freebatteries
power the inverter.Thustheinverter generates asinewave AC power,
which permanentlysupplies the loads.
Designed with the provenon-line, double conversionarchitecture, this
series ofUPS offers thegreatest degree ofavailabilityinpowerprotection
andprovidescontinuous high-quality AC power to connectstrict load,
especially for the basicequipments insomeareasas: finance,
communication, government, traffic, manufacture, education andso on.

check thebatteryconditions. There are two methods to initiatethe battery
self-diagnosis:
1. Through thefunction button
In normal mode, press andhold thefunctionformore than 5seconds
until the buzzer beeps twice.Atthis pointthe indicators (LED7~10)will
blinkcyclically,indicatingthe UPS has workedin battery mode andthe
batteryself-diagnosis has started. The batteryself-diagnosis willlastfor
5secondsdefault.In theevent of abatteryfaultduringbattery
self-diagnosis, theUPS will transfer to normal mode automatically.
2. Through themonitor software
Users canalso initiate batteryself-diagnosisthroughthebackground
monitoringsoftware.

8. 4Checking UPS function
Every time whenconductingfield maintenance, pleasecheck theregular
functionof theUPS, including:
1. Check theoperation status of the UPS
If themain voltage iswithinthespecifications, the UPS shouldoperate
innormal mode;ifthe mainvoltageisabnormal, the UPS shouldoperate
in battery mode. Inboth cases, there shouldbeno faultindication.
2. Check thetransfer between theUPS operation modes
Disconnectthe maininput tosimulateamains failure,theUPS should
transfer tobattery modeand operate normally; thenrecover the mains
input, the UPS should transfer to normal mode andoperate normally
3. Check theLED indicators of the UPS
Duringthecheck processes stated above,check that the LED indication
of the UPS agrees withthe UPS operation mode.
