53
Lost N+X
Redundant
Lost N+X Redundant. There is no X redundant powers 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
If the battery voltage is over 90% of float voltage
If load is over 25%
57
Ambient Over
Temp
Ambient temperature is over the limit of UPS. Air conditioners are
required to regulate ambient temperature.
58
REC CAN Fail
Rectifier CAN bus communication is abnormal. Please check if
communication cables are not connected correctly.
59
INV IO CAN Fail
IO signal communication of inverter CAN bus is abnormal. Please
check if communication cables are not connected correctly.
60
INV DATA CAN
Fail
DATA communication of inverter CAN bus is abnormal. Please
check if communication cables are not connected correctly.
61
Power Share Fail
The difference of two or more power modules’ output current in
system is over limitation. Please adjust output voltage of power
modules and restart UPS.
62
Sync Pulse Fail

68
Outlet Temp Error
Outlet temperature of power module is over the limitation.
Please check if fans are abnormal.
Please check if PFC or inverter inductors are abnormal.
Please check if air passage is blocked.
Please check if ambient temperature is too high.
69
Input Curr
Unbalance
