Troubleshooting
6.1 Introduction
If the UPS shuts down due to a fault condition, caused by an internal malfunction or severe overload, it might need to be
reset to bring it back into operation – see paragraph 6.6. Depending on the nature of the fault, the UPS may either shut
down entirely and disconnect the load supply or transfer the load to the internal bypass.
6.2 Fault identification
Unless there is a total UPS failure, the UPS will generally:
• illuminate the red FAULT LED
• display a Buzzer Code (error code) number on the LCD screen – the code indication may be steady or flashing
depending on other factors
• sound the audible warning alarm – the audible warning may be cancelled by pressing the ON button briefly
• illuminate the warning symbols at the top of the LCD screen if applicable
