2.5. Battery and charging
1.
When the UPS is connected to the mains, it recharges itself automatically. The charger can charge the batteries up
to 90% within 8 hours.
2.
Keep the batteries in full power condition so as to prolong their lifetime as well as their discharging time.
3.
There are electronic and high voltage elements installed in the UPS – ensure that the appliance will be opened only
by technically competent personnel because of the danger of electric shocks.
4.
Respect, follow and use this manual with instructions.
3. PRODUCT FEATURES
3.1. Wide input voltage range
The synchronous online technology for voltage regulation and with an operating input range of 165-275Vac (optional 150-
275Vac) requires a much rarer discharging and charging than usual and extends the effective usage time of the batteries.
3.2. Automatic switching function
! If you don’t need the auto-switch-function, turn off the input breaker on the rear of the device.
Supply the UPS with mains and turn on the input breaker on the rear; the unit starts 15 seconds later to produce
stabilized power for the load.
The batteries supply power promptly when the mains is interrupted. After finishing its discharge, the UPS is shutting
off its long ringing automatically.
The UPS restarts automatically when the main power has recovered after the interruption and recharges the
batteries as well.
3.3. User-specific alarm system
The UPS starts its alarm (frequency once per 5 seconds) when the mains is off and the inverter begins to work. The
sound becomes automatically silent after 40 seconds in order to not disturb the working environment.
The UPS starts automatically its long ringing (frequency 5 times per second) when the batteries are nearly exhausted
in order to remind the persons that the batteries are used up and that the UPS will soon cut out.
When the batteries are almost used up, the UPS shuts down automatically to protect the batteries.
3.4. Protective functions of the Online-UPS
Overload on main power condition: if the load amounts more than 110% on mains condition, the UPS sounds alarm
during 60s. Then it turns to bypass mode, at which the alarm tone stops as well. Normal condition will be regained
as soon as the load has decreased to a normal range again.
Overload on normal inverter condition: if the load amounts more than 110% on inverter power condition, the UPS
alarms with long ringing. It will supply power again as soon as the load is decreased to a normal range within 60s.
The acoustic signal will be terminated simultaneously. Otherwise it shuts down itself automatically. The user needs
either to turn it on again manually by pressing the ON button, or has to wait for the recovering of main power.
Overload on abnormal inverter condition: if the load amounts more than 125% on inverter power condition, the UPS
alarms with long ringing. The UPS cuts itself out after 5s. The user needs either to turn it on again manually by
pressing the ON button, or has to wait for the recovering of main power.
Short-circuit protection on inverter power condition: if the output of the UPS meets transient crest current and short-
circuit strike, it will be limited in some degree if it’s over 10ms and the system shuts down automatically. The user
needs either to turn it on again manually by pressing the ON button, or has to wait for the recovering of main power.
(If the system runs on mains, then the input fuse will melt at first protection. Afterwards the UPS unit will switch
over to inverter mode.).
