ups failure to see mains

[BillP]

Dear friends,

I HAVE 2 BY SUVTP 40KH WHICH ARE EXPERIENCING NO MAINS ERROR. MAINS NOT AVAILABLE IS THE MAIN ERROR EVEN WHEN I CAN CONFIRM THE MAINS AVAILABILITY. THE OTHER ALARM IS BATTERY DISCHARGED. HOW CAN I BE HELPED.

Hello 

Referencing the SUVT Operations Manual, please refer to page 42.

Mains Not Available. Input Freq/Volt Out of Range.

Meaning: The frequency or voltage is out of acceptable range for normal operation.
Corrective Action: Correct the input voltage to provide acceptable voltage or frequency.

Battery Discharged.

Meaning: The UPS is in battery operation and the battery charge is low. Note: Runtime is limited in duration.
Corrective Action: No corrective action is necessary. Shut down the system and the load equipment or restore incoming voltage.

Kind Regards

Haseeb
