1. Brief introduction
1.1 System and model description
The On-Line-Series is an uninterruptible power supply incorporating double-converter technology. It provides perfect protection specifically
for strict load. The double-converter principle eliminates all mains power disturbances. A rectifier converts the alternating current from the
socket outlet to direct current. This direct current charges the batteries and powers the inverter. In the event of power failure, the
maintenance-free batteries power the inverter. Thus the inverter generates a sine wave AC power, which permanently supplies the loads.
Designed with the proven on-line, double conversion architecture, this series of UPS offers the greatest degree of availability in power
protection and provides continuous high-quality AC power to connect strict load, especially for the basic equipments in some areas as:
finance, communication, government, traffic, manufacture, education and so on.

3.2.1 Notes for installation
1) The UPS must be installed in a location with good ventilation, far away from water, inflammable gas and corrosive agents.
2) The UPS should not be tilted. The air inlet port at the lower part of the front panel and the fan outlet port on the rear panel should not be
blocked so as to ensure good ventilation (Allow at least 0.5m of space on each side).
3) In case if the UPS is unpacked, installed and used at very low temperatures, condensation of water drops may appear. It is necessary to
wait until the UPS is fully dried inside out before proceeding to installation and use. Otherwise, there may be a risk of electric shock.
3.2.2 Installation
Installation and wiring must be performed in accordance with the local electric code and the following instructions by professional personnel.
For safety, please cut off the mains power breaker before installation. The battery breaker also needs to be cut off if it is a long backup time
model.
1) Open the terminal block cover located on the rear panel of the UPS (please refer to the appearance diagram).
2) For 6KVA UPS, it is recommended to select the UL1015 10AWG (6mm2) wire or other insulated wire which complies with AWG Standard for
the UPS input and output wirings.
3) For 10KVA UPS, it is recommended to select the UL1015 8AWG (10 mm2) wire or other insulated wire which complies with AWG Standard
for the UPS input and output wirings.
Note: Do not use the wall receptacle as the input power source for the UPS, as its rated current is less than the UPS’s maximum input current.
Otherwise the receptacle may be burned and destroyed. (Please refer to section 1.4)
4) Connect the input and output wires to the corresponding input and output terminals according to the following diagram.
Note: You must make sure that the input and output wires and the input and output terminals are connected tightly.
5) The protective earth ground wire refers to the wire connection between the equipment which consumes electro-equipment and the
ground wire. The wire diameter of protective earth ground wire should be at least as above mentioned for each model and green wire or
green wire with yellow ribbon wire is used.
6) After having completed the installation, make sure the wiring is correct.
7) Please install the leak current protective breaker at the output power distribution panel of the UPS if necessary.
8) To connect the load with the UPS, please turn off all the loads first, then perform the connection and finally turn on the loads one by one.
9) No matter the UPS is connected to the utility power or not, the output of the UPS may have electricity. The parts inside the unit may still
have hazardous voltage after turning off the UPS. To make the UPS have no output, power off the UPS, and then disconnect the utility
power supply.
10) Suggest charging the batteries for 8 hours before use. After connection, turn the input breaker in the “ON” position, the UPS will charge
the batteries automatically. You can also use the UPS immediately without charging the batteries first, but the backup time may be less
than the standard value.
11) If it is necessary to connect the inductance load such as a monitor or a laser printer to the UPS, the start-up power should be used for
calculating the capacity of the UPS, as its start-up power consumption is too big when it is started.

5. Battery maintenance
●This series UPS only requires minimal maintenance. The battery used for standard models is valve regulated sealed lead-acid maintenance
free battery. These models require minimal repairs. The only requirement is to charge the UPS regularly in order to maximize the expected
life of the battery. When being connected to the utility power, whether the UPS is turned on or not, the UPS keeps charging the batteries
and also offers the protective function of overcharging and over discharging.
●The UPS should be charged once every 4 to 6 months if it has not been used for a long time. In the regions of hot climates, the battery
should be charged and discharged every 2 months. The standard charging time should be at least 12 hours.
●Under normal conditions, the battery life lasts 3 to 5 years. In case if the battery is found not in good condition, earlier replacement should
be made. Battery replace event should be performed by qualified personnel.
●Replace batteries with the same number and same type of batteries.
●Keep the ambient temperature between 15℃and 25℃.
●Do not replace the battery individually. All the batteries should be replaced at the same time following the instructions of the battery
supplier.
●Normally, the batteries should be charged and discharged once every 4 to 6 months. Charging should begin after the UPS shuts down
automatically in the course of discharging, the standard charging time for the standard UPS should be at least 12 hours. Discharge the
battery with the load more than 50%.
6. Notes for battery disposal and battery replacement
1) Before disposing batteries, remove conductive articles such as necklace, wrist watches and rings.
2) If it is necessary to replace any connection cables, please purchase the original materials from the authorized distributors or service
centers, so as to avoid overheat or spark resulting in fire due to insufficient capacity.
3) Do not dispose of batteries or battery packs in a fire, they may explode.
4) Do not open or mutilate batteries, released electrolyte is highly poisonous and harmful to the skin and eyes.
5) Do not short the positive and negative electrodes of the battery, otherwise, it may result in electric shock or fire.

Wstęp
1.1 Opis modelu
UPS online dostarcza czyste i niezakłócone napięcie elektryczne. Wyposażony w technologię on-line o podwójnej konwersji. Zapewnia
najwyższa ochronę podłączonych urządzeń. Inwerter przekształca prąd zmienny na prąd stały. Prąd stały ładuje akumulator i zasila inwerter.
W przypadku gdy zasilanie sieciowe zawiedzie, akumulatory bezobsługowe zasilają inwerter. Inwerter generuje prąd przemienny
sinusoidalny, który zasila podłączone urządzenia. Podłączone obciążenie jest całkowicie odizolowane od niedoskonałości sieci zasilającej.

3Montaż
3.1 Rozpakowywanie
1. Wyjmij UPS z pudełka. Upewnij się, że produkt nie został uszkodzony podczas transportu.
2. Upewnij się, że model UPS jest zgodny z zamówieniem.
3. Jeżeli UPS został uszkodzony w dostawie lub model UPS jest niezgodny z zamówieniem, natychmiast skontaktuj się z dostawcą.
3.2 Procedura okablowania
3.2.1 Uwagi do instalacji
1. Nie umieszczaj UPS w pobliżu: wody, łatwopalnych gazów, środków korozyjnych.
2. Postaw UPS tylko w pozycji pionowej. Aby zapewnić dobrą wentylację UPS nie blokuj kratki wentylacyjnej, portu wyjściowego i
bocznych paneli.
3. W przypadku gdy nierozpakowany UPS został umieszczony w niskiej temperaturze, wewnątrz obudowy może wystąpić zjawisko
skraplania pary wodnej. Należy poczekać aż UPS całkowicie wyschnie przed montażem i użyciem. W innym przypadku może to grozić
porażeniem prądem.
3.2.2 Instalacja
Instalacja UPS powinna być wykonana przez wykwalikowany serwis. Dla bezpieczeństwa odetnij zasilanie sieciowe przed instalacją UPS. Jeżeli
jest to model z funkcją długiego czasu podtrzymania, należy również przełączyć wyłącznik zasilania akumulatorowego na pozycję OFF/0.
1) Otwórz pokrywę listwy zaciskowej umieszczoną na tylnym panelu UPS.
2) Dla modelu 6KVA zalecane jest użycie przewodów UL1015 10AWG o przekroju 6mm2lub izolowanych przewodów spełniających
standardy AWG.
3) Dla modelu 10KVAzaleczane jest użycie przewodów UL1015 8AWG o przekroju 10mm2 lub izolowanych przewodów spełniających
standardy AWG.
4) Podłącz przewody wejściowe i wyjściowe do odpowiednich wejść i wyjść na listwie zaciskowej według poniższego schematu:
Uwaga: Upewnij się, że przewody wejścia i wyjścia są mocno dociśnięte
5) Przewodem uziemiającym należy połączyć wszystkie odbiorniki.
6) Upewnij się, że przewody fazowe, zera i uziemienia na wejściu i wyjściu są prawidłowo połączone.
7) Jeżeli rozdzielnia nie jest wyposażona w wyłącznik różnicowo-prądowy należy zainstalować go przy listwie zaciskowej.
8) Wyłącz wszystkie urządzenia obciążające przed podłączeniem ich do UPS. Po podłączeniu, kolejno włącz urządzenia obciążające.
9) Przewody lub gniazda UPS mogą nadal znajdować się pod napięciem, nawet jeśli UPS został wyłączony z zasilania sieciowego.
10) Ładuj akumulator przez 8 godzin przed pierwszym użyciem. Przed podłączeniem akumulatora, przełącz wyłącznik zasilania
akumulatorowego na pozycję OFF/0. UPS rozpocznie automatyczne ładowanie akumulatora.
11) Jeżeli istnieje potrzeba podłączenia do UPS obciążenia o charakterze indukcyjnym, takich jak monitor lub drukarka laserowa, należy
uwzględnić szczytowy prąd rozruchu do obliczenia obciążenia UPS, ponieważ w momencie rozruchu urządzenia te pobierają dużo
większy prąd.
Uwaga: Nie używaj gniazda ściennego jako źródła zasilania UPS, ponieważ prąd znamionowy gniazda jest mniejszy niż maksymalny prąd
pobierany przez UPS. Może to spowodować uszkodzenie lub spalenie gniazda.

4.2.1 Tryb normalny
Wygląd strony głównej na wyświetlaczu w trybie normalnym, ukazuje poniższy obrazek:
Figura 5-2 Tryb normalny
Wyświetlone są ikony zasilania sieciowego oraz inwertera. Widoczna jest również wartość obciążenia oraz poziom naładowania akumulatora.
W trybie ładowania obszar poziomu naładowania akumulatora zmienia się dynamicznie, po zakończonym ładowaniu świeci jednolicie.
1) Jeżeli ikona zasilania sieciowego miga, oznacza to, że wystąpił problem z odwróconą biegunowością (L, N). Może być to
spowodowane niewłaściwym podłączeniem przewodów lub odłączeniem od uziemienia. UPS nadal działa w trybie normalnym. Jeżeli
ikona akumulatora jest zapalona w tym samym czasie, oznacza to, że napięcie lub częstotliwość zasilania sieciowego jest po za
normalnym zakresem wejściowym UPS. UPS działa w trybie akumulatora.
2) Jeżeli obciążenie wynosi powyżej 105%, dwukrotny sygnał dźwiękowy powtarza się co sekundę, w międzyczasie miga ikona
ostrzegawcza, również co sekundę. Odłącz niepotrzebne obciążenie.
3) Jeżeli miga ikona akumulatora, oznacza to, że akumulator nie jest podłączony do UPS lub napięcie akumulatora jest za niskie.
Sprawdź czy akumulator jest poprawnie podłączony do UPS i włącz autodiagnozę akumulatora (przytrzymaj przycisk „F” przez około
pięć sekund). Jeżeli połączenie akumulatora z UPS jest prawidłowe, problem może być spowodowany defektem akumulatora lub
jego zużyciem. Odnieś się do rozdziału 7 „Rozwiązywanie problemów”.
4) Kolejne cztery strony wyświetlacza to:
a) Strona 1 –procent obciążenia
b) Strona 2 –wartość obciążenia
c) Strona 3 –informacje o wejściu
d) Strona 4 - maksymalna temperatura
Uwaga: Podłączenie zasilacza do UPS powinno być przeprowadzone według następujących kroków:
•Podłącz zasilacz do prądu, poczekaj aż jego praca będzie stabilna przed podłączeniem go do UPS. Upewnij się, że do UPS nie jest podłączone
urządzenie obciążające. Następnie włącz UPS zgodnie z procedurą uruchamiania. Po uruchomieniu UPS, podłącz urządzenie obciążające.
•Zalecane jest, aby wybrany zasilacz posiadał dwa razy większą moc niż UPS.
4.2.2 Tryb akumulatora
Wygląd strony głównej na wyświetlaczu w trybie akumulatora, ukazuje poniższy obrazek:
Figura 5-3 Tryb akumulatora
Wyświetlone są ikony zasilania sieciowego oraz inwertera. Widoczna jest również wartość obciążenia oraz poziom naładowania akumulatora.
Jeżeli w tym samym czasie miga ikona zasilania sieciowego, oznacza to, że zasilanie sieciowe nie zachowuje prawidłowych parametrów.
1) Kiedy UPS działa w trybie akumulatora, urządzenie wydaje sygnał dźwiękowy co 4 sekundy. Przytrzymaj przycisk „F” przez około pięć
sekund, aby wyciszyć alarm, przytrzymaj ponownie około pięć sekund, aby przywrócić alarm.
