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
