Battery Mode
The UPS switches to Battery mode in the event of an extreme voltage/
frequency condition or complete utility failure. The battery system
supplies power through the Inverter to generate power for the con-
nected equipment.
When the UPS is in Battery mode, the Battery Indicator illuminates
green and an alarm sounds every 10 seconds.
When a low battery condition occurs, the Battery Indicator changes to
flashing amber and the alarm sounds every half-second. Low battery
warning is defaulted to two (2) minutes but can be configured via Mul-
tiLink. For more information, refer to Troubleshooting section.
!
CAUTION
Turning off the UPS while in either Normal mode or Battery
mode will result in the loss of output power.
NOTE
Once utility power is restored, the UPS resumes normal
operation. At this time, the battery charger begins recharging
the battery. The UPS is capable of OFF-State charging, i.e.,
with utility power, the UPS will charge the batteries as long
as it is plugged in.
