UPS Troubleshooting Guide...
• Symptom: No power output and green "AC LINE" lamp on.
Cause: Blown 2A fuse or system malfunction.
Remedy: Inspect 2A fuse at the front of UPS. Replace if Busted (same rating.) Chirping sound, yellow "CHARGING" lamp & red
LOW BATT" lamp flickering.
Cause: Battery disconnected from UPS or loose battery cable or blown 25A/30A fuse.
Remedy: Check the connection of the battery to the UPS. Re connect cables if it has been disconnected. Clean battery post if it’s
dirty. Check all 25A/30A fuse for signs of meltdown.
• Symptom: Backup time shorter than normal or early beeping for "LOW BATT" alarm.
Cause: Blown fuse.
Remedy: Check all fuse at the front panel for meltdown and replace it with the some rating. If symptom persist, take unit to
dealer for servicing.
• Symptom: "UPS MODE" & "AC LINE" lamp always on, fan running, UPS beeping & "LOW BATT" lamp blinking.
Cause: Blown fuse.
Remedy: Check all fuse at the front panel for meltdown and replace it with the same rating. If symptom persist, take unit to
dealer for servicing.
• Symptom: "UPS MODE" & "AC LINE" lamp always on, fan running, UPS beeping & "LOW BATT" lamp blinking.
Cause: Busted fuse or loose connection at the AC outlet to voltage from electric company too low.
Remedy: Turn off UPS and unplug from outlet. Check all fuse. Replace it with the same rating if busted. Plug UPS back to AC
outlet and switch on. If symptom still persist, check for any loose wiring inside the AC outlet. Refer to a qualified
electrician to do the job. If problem persist, measure the volt age of your AC outlet, If its always below 190 volts,
chances are you have a low voltage problem. Install an Automatic Voltage Regulator (AVR). See AVR connection for
guidance. (page 7) if AVR is already connected, it might be malfunctioning. Check the AVR output voltage. It might be
too low (below 190V) or too high(above 240V).
