Alarm or Event

Possible cause

Remedy

BUS Under Voltage
Fault (Red) LED is On.
Beep continuous.

Code: F022

Indicates that the UPS has bus undervoltage 
fault.

The UPS transfers to bypass mode if 
supporting the load.

BUS Unbalance
Fault (Red) LED is On.
Beep continuous.

Code: F023

Indicates that the positive bus voltage and 
negative bus voltage are too lopsided.

The UPS transfers to bypass mode if 
supporting the load.

BUS Short
Fault (Red) LED is On.
Beep continuous.

Code: F024

Indicates that the bus voltage is decreasing 
very fast.

Contact your service representative.

BUS Softstart Fail
Fault (Red) LED is On.
Beep continuous.

Code: F025

Indicates that the bus could not soft start 
successfully.

Contact your service representative.

Inv Over Voltage 
Fault (Red) LED is On.
Beep continuous.

Code: F032

Indicates that the UPS has inverter 
overvoltage fault.

The UPS transfers to bypass mode if 
supporting the load.

Inv Under Voltage
Fault (Red) LED is On.
Beep continuous.

Code: F033

Indicates that the UPS has inverter 
undervoltage fault.

The UPS transfers to bypass mode if 
supporting the load.

Inv Softstart Fail
Fault (Red) LED is On.
Beep continuous.

Code: F034

Indicates that the inverter could not soft start 
successfully.

Contact your service representative.

Charger Fail
Fault (Red) LED is  flash

1 beep every 1 second
Code: A015

Indicates that the UPS has confirmed the 
charger has failed.

The UPS turns off the charger until the next 
power recycle. Contact your service 
representative.

Battery Over Voltage 
Fault (Red) LED is On.
Beep continuous.

Code: F016

Indicates that the battery voltage is too high.

The UPS will turn off the charger until the 
battery voltage is normal.

Negative power Fault
Fault (Red) LED is On.
Beep continuous.

Code: F0E1

In a parallel system, power of UPS is negative.

Redundancy mode, the fault UPS turn to fault 
mode without output

Increase mode, UPS1& UPS2 turn to fault 

mode.

Parallel cable loss
Fault (Red) LED is On. 
Beep continuous.

Code: F0E2

In parallel system, parallel cable disconnected.

Disconnect parallel cable one turn to fault 
mode.

Parallel system battery 
status
Fault (Red) LED is flash

1 beep every 1 second
Code: A0E6

UPS1 connect battery, UPS2 without battery.

Check battery connect status.

Line input different
Fault (Red) LED is flash

1 beep every 1 second
Code: A0E7

Parallel system, UPS1 line ok, UPS2 line loss.

Check the line input.

Power strategy different
Fault (Red) LED is flash

1 beep every 1 second
Code: A0E9

Parallel system, UPS mode (normal, converter, 
HE) different.

Check UPS OP mode, keep OP mode be the 
same.

Rate power different
Fault (Red) LED is flash

1 beep every 1 second
Code: A0EA

Parallel system rated power different.

Rated power different, not allowed to turn on 
UPS. Keep rated power the same.

HE in parallel
Fault (Red) LED is flash

1 beep every 1 second
Code: A0EB

Parallel system, UPS mode set as HE

HE not allowed in parallel system, change UPS 
mode.
