34.5 Alarms
The UPS is equipped with intelligent internal diagnostics that provide power supply
alarm signals. These signals can be monitored by the service provider so that
corrective actions can be taken. Proper escalation of alarms can dramatically
improve QoS. The alarms are:
• On-Battery: The outdoor ONT is being powered by the UPS battery.
• Replace Battery: The battery failed a periodic test. It should be replaced because
system availability has been compromised (BATTFAIL).
• Battery Missing: The battery is disconnected. The load will not be supported if
the commercial power fails (BATTMISS).
• Low Battery: The battery has been reduced to the point that roughly 20% of the
available runtime is available (BATTLOW).
• Loss of external power: The ac power is not available (PWR).
34.6 Connectors
The UPS has the following input or output connectors:
• input connector: IEC320/C7, 2-wire
• (ETSI) input power cable: 3-conductor Schuko European, CEE 7/7, 2.44 m
• (ANSI) input cord: 5/15 three-prong power cord with a right-angle, pass-through,
8 ft (2.44 m)
• output connector: 3.5 mm removable, 7-pin screw terminal connector (accepts 16
to 26 AWG)
The output connector is a 3.5-mm, removable, 7-pin screw terminal connector that
provides the interface between the UPS and the outdoor ONT. The connector accepts
16 to 26 A. Table 34-4 defines the pinouts.
