TROUBLESHOOTING 

Error codes 

If the products connected to the Backup Power System do not operate and the alarm is 
sounding, check the Backup Power System LED screen for an error code.   
 

Error 
code 

Possible cause 

Solution 

F05 

Low voltage shutdown because battery is 
discharged. 

Recharge battery by plugging the AC 
power cord into a wall outlet.   

F04 

Overload shutdown while supplying backup 
power. The AC product(s) connected are 
consuming more than Backup Power 
System continuous power rating.   
 
The AC products connected have a surge 
power that exceeds Backup Power System 
surge capability.   
 
The AC products connected are 
short-circuited 

Use products with a total power rating 
within Backup Power System 
continuous power rating of 320 W. 
 
Use products with a total starting surge 
power within Backup Power System’s 
capability of 800W.   
 
Have the load serviced by a qualified 
technician.   

F03 

Over-temperature shutdown has occurred. 
The Backup Power System has overheated 
due to poor ventilation, excessive ambient 
temperature, or power demand beyond the 
unit’s five-minute output power capability. 

Disconnect products from the AC 
outlets. Allow the unit to cool for 20 
minutes. Clear blocked fan or remove 
objects covering unit. Move the unit to a 
cooler place. Reduce load to less than 
400 W if continuous operation is 
required.   

F01 

Under-voltage warning. The battery is 
nearly discharged.   

Reduce the load to extend run time, or 
recharge battery by plugging the AC 
power cord into a wall outlet when 
backup power is no longer required.   

F02 

Over-Voltage (voltage > 15.5 +/- 0.3 V) 

  Lower the voltage < 15.0 +/- 0.3 V 

 
Other problem conditions 

 

Problem 

Possible cause 

Solution 

Backup Power 
System will not 
turn on. 

Battery is discharged 
and utility power is not 
available at the wall 
outlet.   

Ensure power is available at the wall outlet.   

No power 
available at the 
120 V AC 

AC outlet has been 
overloaded or the circuit 
breaker has tripped.   

Reduce the number of products plugged into the 
AC outlets. Check the circuit breaker at the back 
the unit. If necessary, reset the breaker by
