If after pressing the ON/SILENCE key, the Emerson UPS does not start, it could be due to two reasons. Either the key holding time is too short, so press and hold the ON/SILENCE key for more than one second until the buzzer beeps. Or there is an overload, in which case you should remove all load and restart the UPS.
Why is the FAULT indicator on and buzzer beeping on my Emerson Adapt?
If the FAULT indicator illuminates, and the buzzer beeps for a long time on your Emerson UPS, it indicates that the parallel address is wrong. Turn on the UPS mains switch and reset the parallel address.
What does it mean if my Emerson Adapt UPS displays 'RECTIFIER FAIL'?
If the buzzer beeps for a long time, the FAULT indicator illuminates, and the LCD displays RECTIFIER FAIL, INVERTER FAIL, AUX SUPPLY FAIL, or OUTPUT FAIL on your Emerson UPS, it indicates an internal fault. The UPS needs repair. Seek technical assistance from the local service center of Emerson.
