Operation mode depends on the priority, inverter (online) and bypass preferences made by the user and
mains, separate bypass mains and battery voltages.
Via this menu; you may choose operation mode of UPS as Online or
Eco Mode.
If system is configured as
Single;
you may choose operation mode
of UPS Online or Eco Mode.
When you touch the

key, a confirmation pop-up bar will
appear.
You should touch

Via this menu; you may choose operation mode of UPS as Online or
Bypass Mode.
If system is configured as
Parallel;
you may choose operation mode
of UPS Online or Bypass Mode. It would be enough to set the
priority on one of the UPS, all the UPSs will pass to Bypass Mode at
the same time.

5.1. Bypass Operation
Devices without separate bypass mains input, absorb energy from the mains. In devices with separate
bypass mains input, energy is drawn from the separate bypass mains.
Loads are fed via static bypass line.
Output voltage has the same amplitude, frequency and waveform as the input voltage.
Current drawn by the loads are only limited by the thermal/magnetic switches over the energy flow path.
Voltage, frequency and waveform of the bypass supply shall be in their tolerance limits, and bypass shall be
enabled for the UPS to operate in this mode.
When the upper provisions are met, the UPS works in bypass mode in the following conditions:
•
During the start-up
•
If the bypass priority is selected
•
If the inverter is disabled or blocked
•
In case of a prolonged overload
You can save energy by selecting the bypass priority. Efficiency in bypass mode is higher than the efficiency
in normal mode. If the bypass priority is selected, the UPS will operate in bypass mode whenever the
frequency/waveform/rms value of bypass mains voltage is in their tolerance limits. If the bypass voltage
goes beyond these limits, the UPS switches into normal operation.
Bypass Operation mode does not provide perfect stability in frequency/waveform/rms value
of the output voltage like in Online Operation. Thus, the use of this mode should be carefully
executed according to the level of protection required by the application.
