GENERAL FEATURES OF THE UPS UNIT
The POWERLINE 31 UPS systems consist of the following functional blocks:
system of rectifiers with PFC (power factor correction)
battery charger,
battery set,
frequency converter produced in high frequency IGBT technology,
automated by-pass system (static BYPASS),
manual (service) bypass system,
microprocessor-based control system with measurement circuits,
Upon converting AC power (from the three-phase mains), the input rectifier supplies
the unit's internal direct current bus. The applied power factor correction system
allows to radically reduce the consumption of reactive power from the mains. The DC
voltage bus is the basic source of power for the inverter system which in turns
generates single-phase, sinusoidal AC voltage with model parameters to be used to
power the loads. Batteries are charged with an independently operating charger. The
charging power has a very low variable component, translating into extended battery
life. The microprocessor-based control system ensures precision and reliability of the
entire power supply system.
The automated bypass system helps to increase the overall operating security of the
entire system. In case of the failure of the inverter, the power from mains is supplied
directly to the receivers. In this way the automated by-pass system works as an
additional passive protection of the load.
The additional manual bypass allows switching over completely to supplying power to
the connected loads from the mains only. That way, maintenance and service works
can be completed conveniently.

FIRST START-UP
When the UPS unit is started for the first time, it may be necessary to leave it
connected to the mains to charge the batteries. To do this simply connect the UPS
unit's mains lines. The UPS unit will charge its batteries regardless of the mode of
operation (ONLINE - the UPS is on and the inverter is operating, OFFLINE - the UPS
is off, the inverter is not operating, the output is supplied by the bypass).
CAUTION! The batteries reach their full capacity after approximately a
month of mains operation mode.
DESCRIPTION OF THE OPERATION OF THE POWER
SUPPLY UNIT
The POWERLINE UPS unit is a modern electronic device, an autonomous source of
~230 V sine voltage. This unit belongs to a series of uninterruptible ONLINE class
UPS devices whose characteristic feature is constant transformation of power. This
feature allows POWERLINE units to condition the power in the output line.
Regardless of voltage fluctuations and distortions on the input, the POWERLINE
units generate, throughout operation, sinusoidal waveform of ~230 V in the output.
The UPS unit operates in the Line mode (without drawing any energy from the
batteries) in a wide range of voltages ~304÷478 V (voltage between phases),
supplying receivers with ~230 V. Another advantage of constant power
transformation featured in ONLINE UPS units is that there is no interruption when
switching to another source of power (mains - battery). Loads connected to the UPS
output do not even detect switching between the mains and battery operation.

The UPS unit goes into BYPASS mode when the inverter is overloaded, the
permissible temperature is exceeded or the inverter is damaged, and also when the
unit is switched off with the OFF pushbutton in the control panel. In BYPASS mode
the voltage is supplied to the output directly from the input line via a mechanical
switch (relay). If the UPS unit has entered BYPASS mode due to overload or
exceeded permissible temperature, the unit will cyclically check the load and the
inverter's temperature. When these parameters are back to standard levels, the UPS
unit will restart the inverter. In BYPASS mode the UPS unit does not protect its
receivers from power losses. The voltage from the input line is directed to the unit's
output through an internal filter.
LINE mode (mode "02")
Figure 7: LINE MODE (MODE "02")
Upon connecting the UPS unit to the mains, voltage is supplied to its output and
batteries are being charged. In such cases the output receives power from the
internal BYPASS line. Switch the UPS unit logically on to put it in the line mode
(press the ON pushbutton in the control panel for about 1 second). Once the UPS
unit's self-diagnostics is over, the device is ready to operate and supplies power to
the output (after the power from the input lines is transformed) through the inverter
system. The UPS unit switches to battery mode if the mains parameters are incorrect
(voltage and/or frequency). When the UPS unit is in the Line mode, power is supplied
to the output.

CAUTION! Switching the UPS unit with the OFF pushbutton, located in
the control panel, will not stop providing power to the device's output.
The voltage present in the output disappears only when the input line is
disconnected.
BATTERY mode (mode "03")
Figure 8: BATTERY MODE (MODE "03')
If the input supply lines do not meet the mains correctness criteria, the UPS unit will
switch to the back-up mode (battery operation). In the battery mode, the inverter unit
supplies the energy stored in the batteries (after it has been transformed) to the
output. The duration of the time power is being supplied in this way depends on the
power accumulated in the batteries (specifically the number of batteries and battery
packs used).
If there is no power in the mains, the UPS unit is switched on just like in the Line
mode, except that once the self-diagnostics is over, the LCD display shows the view
as in Fig. 8.
BATTERY TEST Mode (mode "04")
In the BATTERY TEST mode, the LCD panel displays the same information as in the
BATTERY mode. This mode's code is "04". When the UPS unit operates in this
mode, the indicators of insufficient or excessive input voltage are not operating.
The BATTERY TEST mode is switched on for about 10 seconds, by pressing the
"ON" button when the UPS unit is in the Line mode (mode "02").
