Operating Manual
42 Inverter overload RMS current drawn from any of the output lines exceeds its nominal value.
43 Bypass active UPS is on Bypass Operation.
44 Inverter passive Inverter does not operate now.
45 Output voltage failure Output voltage is beyond its limits
46 Master com. lost This alarm is observed when information ow from master ups is interrupted
47 Input voltage high Input voltage is higher than its limit.
48 Input voltage low Input voltage is lower than its limit.
49 Rec. not sync. with Inp. Frequency of input voltage is beyond the frequency range for bypass operation or bypass mains voltage is very low
50 Inp. ph. seq. wrong Phase sequence of input mains voltages is not OK.
51 Rectier temp. high Rectier block temperature is very high.
52 Rectier overload RMS current drawn from any of the input lines exceeds its nominal value.
53 DC voltage high DC bus voltages are higher than its upper limit.
54 DC voltage low DC bus voltages are lower than its lower limit.
55 Rectier passive Rectier does not operate now.
56 Output breaker open Output Circuit Breaker is at “OFF” position.
