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")

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.
