While UPS operates in Online Operation, UPS switches to bypass automatically (in case the mains
voltage and frequency is within the limits of bypass) in the following conditions;

Inverter Fault (Er10…)

Prolonged Overload (Er12)

High Temperature (Er11)
After these conditions are eliminated, the UPS automatically returns to inverter.
Bypass voltage range can be adjusted to wider and narrow one.
* It shows Bypass Voltage is adjusted to narrow one.
* It shows bypass voltage is adjusted to wider one.
Eco and Bypass Operation Voltage Range
The mains voltage is required to be in certain range for Eco and Bypass Operation. Bypass range is
187 V – 259 V. In case the input voltage decreases below 187V or increases above 259V; if UPS runs
in Eco Operation UPS switches to Online Operation (norl); if UPS runs in Online Operation (norl) it
can not switch to Bypass/Eco Operation even if a fault occurs. If the batteries and the inverter are
suitable to supply the loads, UPS switches to Battery Operation.
To return to Eco Operation; the mains voltage should return to under 242V or over 200V.
5.4. Battery Mode
In this operation, energy is drawn from the batteries. The loads are supplied via inverter. Output
voltage is sinusoidal and has a regulated amplitude and frequency. It is independent from the
battery voltage. Battery voltage should be in acceptable limits and the inverter should be enabled
for the UPS to operate in this mode.
UPS operates in Battery Operation in the following cases:

While UPS is operationg in Online Operation or Eco Operation, if the rectifier is disabled or
frequency/waveform/rms value of mains voltage is not in acceptable limits.

If the batteries are connected and UPS is started-up as COLDSTART, UPS runs in Battery
Operation and supplies the energy needed for the loads from the batteries.
