Standby Mode

When the UPS is turned off and remains plugged into a power outlet, the UPS is in Standby mode and utility power supplies the connected equipment. The UPS is not supporting the load, but is ready to assume the load on command.

The notice and alarm screens are visible only when notices or alarms are active. There is a separate screen for each active notice or alarm. If there are no active notices or alarms, a “No Active Alarms” message appears in a single screen between the UPS status summary and the battery status screen. If there are multiple notices or alarms, scroll through each notice or alarm screen to reach the first battery status screen.

NOTE: Events are not shown in status summary screens. They appear only in the Event Log.

Table 5 describes the available battery status screens. Only one battery status is available at a time.
