BATTERY MODE OPERATION
Battery mode occurs in event of extreme input conditions or complete utility failure.
The battery system along with the bi-directional converter generates power for the
connected load.
During battery mode an alarm sounds every 10 seconds. This will change to 2
beeps every 5 seconds when battery runs low (approximately 2 minutes
remaining). Each load/battery level indicator represents a 25% capacity level. As
capacity decreases, fewer indicators remain illuminated. Utility LED will flash every
second indicating the UPS is operating from battery mode.
Battery mode supports a full rated load for approximately 5 minutes before it shuts
down. To increase this time, turn off non essential pieces of equipment (such as
idle computers and monitors).
WARNING: Turning off the UPS while in battery mode will result in loss of output
power.
The figure below displays approximately 51-75% battery capacity remaining.
BATTERY RECHARGE MODE
The UPS resumes normal operation once utility power is restored. At this time, the
bi-directional converter begins recharging the battery whether the UPS in ON or
OFF.
