Chloride 20KVA EPEM

Can anyone help me about the problem on UPS reserve supply fault (reserve supply low) this UPS alarm always but when i try to check the input its 367-370 on mains input although its transitory (its iether back to normal or permanently fault) no action required on the side of operator anyway.. has someone encountered about this problem?
 

Is 370 volt your normal input? There is a adjustment on the static switch board that raises or lowers a window for the input voltage at the point where it will alarm.
 

yup! its already rectified the problem i try to send e-mail to chloride team and they told as about this Static switch setting of sw2.1 = on sw2.2 = off for 230Vac
sw2.1 = off sw2.2 = off for 220vac now there's no more alarm on the unit. anyway ups has an input isolation transformer 380/208vac thanks joe1314 for the reply. and keep in touch here in EDA board thanks!
