6.5. Operating mode and status description

If parallel UPS systems are successfully set up, it will show one more screen
with "PAR" in parameter 2 and be assigned number in parameter 3 as below
parallel screen diagram. The master UPS will be default assigned as "001" and
slave UPSs will be assigned as either "002" or "003". The assigned numbers
may be changed dynamically in the operation;
• AC mode
When the input voltage is within acceptable range, UPS will provide pure
and stable AC power to output. The UPS will also charge the battery at AC
mode.
• ECO mode (Efficiency Corrective Optimizer)
When the input voltage is within voltage regulation range and ECO mode
is enabled, UPS will bypass voltage to output for energy saving.
