APC SMC10002U User Manual

On Line: The UPS is supplying conditioned AC power to connected 
equipment.

Green mode: The UPS is operating at the most efficient level, bypassing 
unused AVR components while acceptable AC voltage is present. The UPS 
will enter and exit Green mode automatically and will not compromise 
power protection.

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 / Min: This indicates the battery runtime minutes 
that remain if the 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 
battery is fully charged. Each bar represents 20% of the battery charge 
capacity. 

Overload: The equipment connected to the UPS is drawing more power 
than the voltage rating allows.

Event: The event counter indicates the number of events that occurred to 
cause the UPS to switch to battery operation.

Automatic Voltage Regulation (AVR): The UPS has an AVR boost and 
trim feature that automatically regulates high or low levels of input voltage 
without using battery power. The 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 UPS is compensating for low input 
voltage.
When illuminated, the UPS is compensating for high input 
voltage.

In: Input voltage.
Out: Output voltage.

System Fault: An internal system fault has occurred. The fault number will 
illuminate on the display. Refer to “Display interface features” on page 8.

Mute: An illuminated line through the icon indicates that audible alarms 
are

 

disabled.

Battery Fault: The icon will flash to indicate that the battery is 
disconnected. 
When the icon remains continuously illuminated the UPS has failed a Self-
Test or the battery is near the end of its service life and should be replaced.
Refer to “LCD status indicators” on page 7. 

On Battery: The UPS is supplying battery backup power to the connected 
equipment.
