Chapter 4 Commissioning of UPS

Step 5 : After the UPS transfers from bypass to inverter, the bypass indicator turns off, and the inverter and the load indicator turns on. The transfer may fail if the phase rotation of bypass and inverter output are different.

During operation, if the AC power recovers after failure, the rectifier will restart automatically after some time. If the UPS transfer to generator power, the monitoring system will determine the quality of the generator supply. The time it takes to determine this, ranges from 1 second to 255 seconds.

After startup, use the keypad to set the functions of the UPS.

Note

Power failure means the line to neutral voltage is lower than 120V or the Line to Line voltage is lower than 208V over 10 msecs.
