Battery Mode Operation
Battery mode occurs in event of an extreme input voltage condition or complete utility failure. The battery system supplies power through the DC to DC converter to the inverter
AC INPUT BATTERY UPS ON BYPASS to generate power for the connected load.
During battery mode an alarm sounds every 10 seconds. This will change to two beeps every
5 seconds when the battery runs low (approximately 2 minutes remaining, but this is user configurable). The AC Input LED will extinguish, and the Battery LED will illuminate to warn that a utility problem has occurred. Each battery level indicator represents a 20% capacity level. As capacity decreases, fewer indicators remain illuminated. Refer to Troubleshooting section.
For approximate battery run times, refer to the Battery Run Times charts in this manual. These times are approximates based on resistive load and an ambient temperature of 77°F (25°C). To increase this time, turn off non- essential pieces of equipment (such as idle computers and monitors) or add the optional external battery cabinet.
! CAUTION
Turning OFF the UPS while in battery mode will result in loss of output power.
Battery Recharge Mode
Once utility power is restored, the UPS resumes normal operation. At this time, the Battery Charger begins recharging.
