The battery mode indicator lights up when the main power source fails and the
2145 UPS is running on battery power. The alarm beeps once every five seconds.
When main power returns, the 2145 UPS returns to normal mode and the battery
recharges. The battery mode indicator then shuts off and the alarm ceases.
General alarm indicator
The general alarm indicator on the 2145 uninterruptible power supply (2145 UPS)
turns on when a power or temperature problem occurs.
When the general alarm indicator is accompanied by the audio alarm beeping
every five seconds, the battery is low. If the audio alarm is continuous, the internal
temperature of the 2145 UPS is too high or there has been a momentary output
overload.
