Description
Online-mode
UPS is running through the inverter (Online-mode)
Battery-mode
UPS running on battery.
Bypass-mode
The power used by the load is supplied from the mains power via
internal filter.
Note that if there is a power failure and the UPS in on bypass, it will
not transfer back to mains or to battery-mode. (This only happens if
the UPS is in ECO-mode).
Stand-by-mode
UPS is running on bypass but there is no power in the output.
ECO-mode
After the UPS is turned on, the power used by the load is supplied
from the mains via internal filter if its power is in an acceptable
range. This guarantees higher efficiency of the UPS. In case of
mains failure, the UPS transfers to Online-mode or Battery-mode
and the load is supplied continuously.
Note: ECO-mode can be enabled/disabled through the LCD
settings or through the monitoring software.
Warning: The transfer time of UPS output from ECO-mode to
battery-mode is 10ms and not recommended for sensitive loads.
Converter-mode
In converter-mode, the UPS runs with fixed output frequency (50Hz
or 60Hz). In case of mains power failure, the UPS transfers to
battery-mode and the load is supplied continuously.
Note:
- Converter-mode function can be enabled/disabled through the
LCD settings or the monitoring software.
- The load should be de-rated to 60% in converter-mode with single
phase input. No de-rating is needed in three phase input
configuration.
Warning
Warnings indicate abnormal situations that do not stop the UPS
from working. In these cases, the UPS continues running but the
user should do corrective actions. See Section 7 for details.
