OPERATING MODES
NORMAL MODE OPERATION- UPS mode
During normal operation, mains power provides energy to the UPS. The filters, the power factor correction circuit and
the inverter process this power to provide computer grade power to connected loads. The UPS maintains the batteries in a fully charged state.
The four green LED’s indicate an approximate level of load in 25% increments. If the UPS becomes loaded beyond full rating, the fifth (amber) LED indicator will illuminate and sound an alarm.
The display template indicates the percentage of load on the UPS output.
BATTERY MODE OPERATION
Battery mode occurs in event of an
extreme input voltage condition or complete mains failure. The battery system supplies power through the
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). The AC Input LED will extinguish, and the Battery LED will illuminate to warn that a mains problem
has occurred. Each load/battery level indicator represents a 20% capacity level. As capacity decreases, fewer indicators remain illuminated. Refer to the Troubleshooting Guide.
To increase this time, turn off
CAUTION: Turning off the UPS while in battery mode will result in loss of output power.
Once mains power is restored, the UPS resumes normal operation. At this time, the Battery Charger begins recharging the battery.
