Turn On/Off Ups - KStar YDC9300-B Operation Manual

◆ECO Mode
When the UPS is at AC Mode and the requirement to the load is not critical, the UPS can be set
at ECO mode in order to increase the efficiency of the power supplied. At ECO mode, the UPS
works at Line-interactive mode, so the UPS will transfer to bypass supply. When the AC is out of set
window, the UPS will transfer from bypass to Inverter and supplies power from the battery, and then
the LCD shows all related information on the screen.
◆Maintenance mode (Manual Bypass)
A manual bypass switch is available to ensure continuity of supply to the critical load when the
UPS is out of order or in repair and this manual bypass switch bears for equivalent rated load.
