HP R5500 warning alarm messages?

Hi, from the past few days we are getting numerous alert messages (around 150 messages)from our HP R5500 UPS "Bypass Not Available Cleared" and "Bypass Not Available"
Does anyone know what it means?
We recently added a management card on this UPS (approx 1 month ago) Errors have started to appear since last week.
Any help / info would be appreciated.

Bypass Not Available

Bypass mode is currently unavailable due to the voltage or frequency being outside the valid operating range for the UPS.

Can you call an electrician to check the input voltage to the UPS?
