57
Redundant
module in system.
54
EOD Sys
Inhibited
System is inhibited to supply after the battery is EOD (end
of discharging)
55
Battery Test Fail
Battery Test Fail. Check if UPS is normal and battery voltage
is over 90% of float voltage.
56
Battery
Maintenance Fail
Check
If UPS is normal and not any alarms
