UPS T1500 G2 Intl (AF408A) on ML350 G5 detects high voltage

Looking at the logs, the ups has been switching into buck mode as it appears to detect a high voltage and then it reduces output to about 215 volts, seems to be doing this a few times a day and has been going on for 3 yrs!

 

 

 

battery test passes and have had no issue with the performance of the UPS.

 

Current firmware is 692233 Rev E

 

i see there is a later firmware 2360 Rev A but it seems to fix a problem with falsely notifying battery failure.

 

Have no reason to suspect this is a supply voltage problem as have other medical grade equipment on same external supply.

 

Is this likely to be resolved with a firmware upgrade? ( fw upgrade requires a serial cable)
