The information below indicates various symptoms a user may encounter in the event the
UPS develops a problem. Use this information to determine whether external factors cause
the problem and how to remedy the situation.
1. The fault indicator will flash every second to indicate the UPS detected a problem.
2. An alarm will sound to alert that the UPS requires attention.
3. One or more additional load/battery level LED segments will be illuminated to provide a diagnostic aid to
the operator, as described below:
A. UPS fault (fan failure, battery overcharge)
NOTE: The internal fan operates intermittently as needed
B. UPS failed battery test
D. UPS shutdown due to output overload time-out
A.&B. UPS shutdown due to main input relay failure/output short circuit
A.&D. UPS shutdown due to over temperature condition
B.&D. UPS shutdown due to command from communication ports
(remote shutdown or SNMP)
The fault indicators will be illuminated indefinitely while battery charger is operational,
or for a maximum of 5 minutes while battery charger is not operational.
If a problem persists, consult your dealer immediately.

| Problem | Cause | Solution |
| UPS fails to start when On/Off button is pressed | UPS output short circuited or overloaded | Ensure Ups is off. Disconnect all loads and ensure nothing is lodged in output receptacles. Ensure loads are not detective or shorted internally |
| Internal fuse is blown, indicating internal fault | Do not attempt to open or service the Ups. Contact your dealer | |
| Mains indicator flashing | UPS not plugged in | UPS is operating in battery mode. Make sure that UPS is securely plugged into the wall receptacle |
| UPS input protection has opened | UPS is operating in battery mode. Save data and close applications. Replace UPS input fuse or reset input beaker, then restart UPS | |
| Mains voltage out of UPS input range | UPS is operating in battery mode. Save data and close applications. Ensure mains supply voltage is within acceptable limits for UPS | |
| UPS has reduced battery time | Battery not charged | Keep UPS plugged in continuously at least 24 hours to recharge batteries |
| UPS is overloaded | Check load level display and remove non-essential loads | |
| Batteries may not be able to hold a full charge due to age | Replace batteries | |
| “Fault” indicator and diagnostic LED “A” are illuminated | UPS fan failure or battery overcharge | UPS requires service. Contact your dealer |
| “Fault” indicator and diagnostic LED “B” are illuminated | UPS failed the battery test. | Replace batteries |
| UPS shut down. “Fault” indicator and diagnostic LED “D” are illuminated | UPS overloaded or load equipment is faulty | Check load level display and remove non-essential loads. Recalculate load VA and reduce number of loads connected to Ups. Check load equipment for faults |
| UPS shut down with the “Fault” indicator and diagnostic LEDs “A” and “B” are illuminated | UPS shutdown due to internal failure | UPS requires service. Contact your dealer |
| UPS shuts down with the “Fault” indicator and diagnostic LEDs “A” and “D” are illuminated | UPS shutdown due to an internal over temperature condition | Ensure UPS is not overloaded, ventilation openings not blocked, or room ambient temperature not excessive. Wait 30 minutes to allow UPS to cool, then restart UPS. If it does not restart, contact your dealer |
| UPS shuts down with the “Fault” indicator and diagnostic LEDs “B” and “D” are illuminated | UPS shutdown due to a command from the communication port | Your UPS has received a signal or command from the attached computer. If this was inadvertent, ensure the communication cable used is correct for your system. For assistance, contact your dealer |
