3.0 Working Principle
3.1 In AC mode
When UPS is in normal working mode, AC goes through the filter and the harmful
waves are filtered. After that, AC charges the battery and meanwhile, passes UPS
AVR and the filter and provide power for the equipment.

5 | ENGLISH
3.2 AC Failure
When AC fails, the battery will supply power to the inverter and then passes filter and
provide power for the equipment, ensuring the continuous power supply.

•Overload, when the UPS is overloaded, UPS will alarm once every 0,5 second
•Fault, if there is a faulty operation of the UPS, UPS will alarm continuously.
4.4 Lock Phase Function
In AC mode, the UPS system automatically tracks AC phase and ensures that the
output wave form of the inverter is the same with AC voltage wave form. In this way, it
reduces the peak pulse and surge voltage to minimizes the interference and damage
to the equipment.
4.5 The Function of the Self-set Frequency
When the UPS is turned on for the first time, the acquiescence frequency is 50/60Hz;

2.0 Opmerkingen over veiligheid
Voldoe aan het volgende om de UPS veilig te gebruiken:
•Laad de accu ten minste 24 uur voordat u de UPS gaat gebruiken.
•Na het ontladen van de accu of na meer dan drie maanden niet gebruikt te zijn,
moet de accu direct worden geladen gedurende minstens 12 uur om er voor te
zorgen dat de accu vol is en om onnodige schade aan de accu te voorkomen.
•De UPS is specifiek voor computers ontworpen en moet niet worden verbonden
met enige inductieve of capacitieve belasting, zoals een elektromotor,
daglichtlamp, laserprinter, enz.
•Het is niet aan te bevelen de UPS te gebruiken in combinatie met medische
apparatuur.
•De behuizing van de UPS kan 50 graden worden bij gebruik. Dit is normaal.

4 | NEDERLANDS
•Als de wisselstroom uitvalt en de "aan/uit"-knop op de voorkant wordt ingedrukt,
geeft de UPS stroom af; als de "aan/uit"-knop wederom wordt ingedrukt, geeft de
UPS geen stroom af.
•Het is verboden om de behuizing te openen, omdat dit gevaar door elektriciteit
kan opleveren. Als er een probleem is, moet u de aanwijzingen van experts
opvolgen.
•Breng de UPS niet in contact met vloeistoffen om kortsluiting, elektronische
schokken of brandgevaar te vermijden.
•Bij abnormaal gedrag van de UPS moet u direct de stroomtoevoer uitschakelen en

•Zorg er voor dat de UPS zich dichtbij een stopcontact bevindt zodat u in
noodgevallen snel de stekker uit het stopcontact kunt trekken.
Let op! De UPS moet geaard zijn.
3.0 Werking
3.1 Lichtnet modus
Als de UPS in de normale werkstand staat, passeert wisselstroom het filter en worden
de schadelijke golven gefilterd. Daarna laadt de wisselstroom de accu en passeert
intussen de UPS, AVR en het filter en levert energie voor de apparatuur.

5 | NEDERLANDS
3.2 Lichtnet storing
Bij een lichtnetstoring levert de accu stroom aan de omvormer waarna deze het filter
passeert. Vervolgens wordt de aangesloten apparatuur van stroom voorzien,
waardoor een continue voeding verzekerd is.
3.3 Aansluiten van de UPS
De UPS heeft de volgende aansluitingen:
• 1 RS232 seriële poort
• 1 USB poort
• Stroom uitgang poorten (het aantal verschilt per model)
3.4 Accu en laden
•Als de UPS op het lichtnet is aangesloten, laadt de lader de accu volledig op in
ongeveer 10 uur.
•Als de accu leeg is, moet u deze direct laden om de levensduur van de accu te
verlengen.
4.0 Belangrijkste eigenschappen
4.1 Normaal bedrijf
•Sluit de UPC op het lichtnet aan en druk op de "aan/uit"-knop op de voorkant; de
UPS wordt ingeschakeld en de wisselstroomuitgangen leveren een
gestabiliseerde spanning.
•Bij storing in het lichtnet levert de UPS direct energie aan de apparatuur. En als
de accu leeg is, schakelt de UPS automatisch uit.
•Als het lichtnet weer stroom levert, schakelt de UPS automatisch in.
