Setting the Battery Low Alarm Level
The default Battery Low Alarm Level setting provides approximately
2.5 minutes of battery warning for a UPS. Additional EBMs installed in a
parallel system can provide a longer warning time. To adjust the Battery
Low Alarm Level setting to provide different warning times for a parallel
system with additional EBMs installed, see Table 5.
