8. Troubleshooting
The online series UPS is designed for durable, automatic operation
and issues alarms to alert you whenever potential operating
problems occur. Usually the alarms shown by the control panel do
not mean that the output power is affected. Instead, they are
preventive alarms intended to alert the user. Active alarms are
accompanied by an audible buzzer.
The control panel provides troubleshooting information from two
main menus:
UPS status menu: Access to all active alarms
Event Log menu: Access to the most recent 50 events, which
may include active and closed alarms
