52 Shield M10U user manual
46 Bypass Fan Fail At least one of bypass module Fans Fails
47 Manual Shutdown
The N# Power Module is manually shutdown. The power module shuts down
rectifier and inverter, and there’s on inverter output.
48 Manual Boost Charge Manually force the Charger work in boost charge mode.
49 Manual Float Charge Manually force the charger work in float charge mode.
50 UPS Locked Forbidden to shutdown UPS power module manually.
51 Parallel Cable Error
Parallel cables error. Check:
If one or more parallel cables are disconnected or not connected correctly
If parallel cable round is disconnected
If parallel cable is OK
52 Lost N+X Redundant Lost N+X Redundant. There is no X redundant powers module in system.
53 EOD Sys Inhibited System is inhibited to supply after the battery is EOD (end of discharging)
54 Battery Test Fail
Battery Test Fail. Check if UPS is normal and battery voltage is over 90% of float
voltage.
55
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%
56 Ambient Over Temp
Ambient temperature is over the limit of UPS. Air conditioners are required to
regulate ambient temperature.
57 REC CAN Fail
Rectifier CAN bus communication is abnormal. Please check if communication
cables are not connected correctly.
58 INV IO CAN Fail
IO signal communication of inverter CAN bus is abnormal. Please check if
communication cables are not connected correctly.
59 INV DATA CAN Fail
DATA communication of inverter CAN bus is abnormal. Please check if
communication cables are not connected correctly.
60 Power Share Fail
