Installation and Operation Back-UPS 1250, 1300, 1500 7
Modes of operation
Press DISPLAY to scroll through the display screens.
Load Capacity: The load capacity percentage is indicated by the number of load bar sections illuminated. Each
bar represents 20% of the load capacity.
Estimated Run Time: This indicates the battery runtime minutes that remain if the Back-UPS switches to
battery power.
Battery Charge: The battery charge level is indicated by the number of load bar sections illuminated. When all
five blocks are illuminated, the Back-UPS battery is fully charged. Each bar represents 20% of the battery charge
capacity.
Overload: The equipment connected to the Back-UPS is drawing more power than the voltage rating allows.
Event: The event counter indicates the number of events that occurred to cause the Back-UPS to switch to
battery operation.
Automatic Voltage Regulation (AVR): The Back-UPS has “boost” and “trim” AVR that automatically regulates
high or low levels of input voltage without using battery power. The Back-UPS also features AVR Bypass which
temporarily deactivates the AVR circuitry when the input voltage is within normal range. This conserves battery
power and helps to maximize battery life.
When illuminated, the Back-UPS is compensating for low input voltage.
When illuminated, the Back-UPS is compensating for high input voltage.
In: Input voltage.
Out: Output voltage.
System Faults: An internal system fault has occurred. The fault number will illuminate on the display.
See “Specifications” on page 11.
Load: The total voltage, in watts and percentage used by the devices connected to the Battery Backup outlets.
Mute: An illuminated line through the icon indicates that the audible alarm is disabled.
Replace Battery: The battery is nearing the end of its service life. Replace the battery.
On Battery: The Back-UPS is supplying battery backup power to the connected equipment.
