Operation Modes
z
Online Mode:
During on-line mode, the on-line LED
illuminates (green). The critical load is supplied by
the inverter, which derives its power from the utility AC power, and the UPS charges the bat-
teries as needed and provides power protection to the equipment.
z
Standby Mode:
In standby mode, the input power is from the utility AC power and the UPS charges the batter-
ies.
z
ECO Mode:
You can manually set the UPS to ECO mode. In ECO mode, when the utility input voltage and
frequency are within the range of rating voltage ±10% and rating frequency ±6%, the load is
supplied by the utility power and the bypass LED
illuminates (yellow); if out of the range,
the load is supplied by the inverter and the on-line LED
illuminates (green).
z
Battery Mode:
When the UPS is operating during a power outage, the batteries provide DC power, which
maintains inverter operation to support the critical load. During battery mode, the battery LED
illuminates (green). The status of the battery is as follows.

Converter Mode:
When the UPS is manually set in converter mode, the output frequency can be set as 50Hz
or 60Hz. After the output frequency is set up, the system will automatically disable the bypass
function. Please note that once the inverter shuts down, there is no bypass output. During con-
verter mode, the on-line LED
illuminates (green).
