Description
Online-mode
UPS is running through the inverter (online-mode)
Battery-mode
UPS is running on battery. The alarm buzzer sounds every 4 seconds.
Bypass-mode
The power used by the load is supplied from the mains power via an 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.
In bypass-mode the alarm buzzer will sound every 2 minutes.
Bypass without
output
UPS is running in bypass but there is no power in the output.
ECO-mode
(HE: High
efficiency-mode)
After the UPS is turned on, the power used by the load is supplied from the mains via an internal filter if
its power is in an acceptable range. This guarantees higher efficiency of the UPS. In case of a mains
failure, the UPS transfers to Online-mode or Battery-mode and the load is supplied continuously.
Note:
ECO-mode can be enabled 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 a mains failure,
the UPS transfers to battery-mode and the load is supplied continuously.
Note:
- Converter-mode function can be enabled through the LCD settings or the monitoring software.
- The load is de-rated to 70% in converter-mode.
Warning
Warnings indicate abnormal situations that do not stop the UPS from working. The UPS continues
running but the user should perform corrective actions. For more information, see Chapter 6.
Fault
In case of failure, the UPS may disconnect the load or transfer to bypass depending on the cause of the
failure. The UPS alarm sounds a continuous signal and the backlight of the UPS will turn red. For more
information, see Chapter 6.
Overload
When the UPS is on overload, an alarm sounds twice every second. Disconnect unnecessary loads one
by one to decrease the load. The load should be lower than 90% of its nominal power capacity in order
to stop alarming.
Battery test
UPS is performing a battery test.
Battery disconnected
The battery is disconnected or defective. The UPS alarm sounds.
