5.2. Eco Mode (Eco)
In this mode, as long as the mains voltage and frequency within the limits, the load is supplied by
the mains in a controlled manner (the inverter is in standby state). The purpose of using this mode
is to increase the efficiency up to 98% and to provide energy saving; since the loads are supplied by
the mains directly, the loads are unprotected against any possible future risks. (e.g. surge voltage,
etc.).
* It shows the UPS is operated in “Eco mode”.
To operate the UPS in Eco Mode, it must be chosen through the settings menu. UPS does not switch
to Eco Operation automatically. "Eco" is chosen as the operating mode hence UPS operates
continuously in this mode.
UPS switches from Eco Operation to another mode under the following conditions:

In case of the mains voltage or frequency out of the limits of the bypass (UPS returns to Eco
Operation when the mains voltage or frequency turn back to within the limits of bypass).

In case Online Operation (norl) is set as Operation mode through settings menu.
5.3. Bypass Mode
If UPS is commissioned through the mains it starts-up on Bypass Mode. This mode can be choosen
by the user by pressing OFF key while UPS operates on norl mode. In this case OFF written on the
front panel but the loads are supported by the mains. Bypass mode can be understood from the
flow diagram placed on the left side of the front panel.
Eco 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.
Eco Operation mode does not provide electronic short circuit protection like in Online
Operation. If a short circuit occurs on the output during this operation, the thermal/magnetic
protection will act and all loads will be deenergized.
Prolonged overloads in Eco Operation may cause the thermal/magnetic protection act. In this
case, all loads will be deenergized.
