To confirm your APC BC650-RSX761 Back-UPS is providing battery backup power, observe the unit's status indicators. Here's a breakdown:
- Power On Indicator (Green LED): A lit green LED signifies the Back-UPS is running on standard utility power, which means everything is functioning correctly.
- Overload Alarm (Constant Tone): A constant tone indicates the Back-UPS is overloaded. You'll need to unplug some devices to reduce the load.
- On Battery Indicator (Green LED Not Illuminated, 4 Beeps Every 30 Seconds): This is the key indicator for battery backup. If you hear four beeps every 30 seconds, it confirms the Back-UPS is providing battery power during an outage.
- Low Battery Indicator (Flashing Green, Rapid Beeps Every 1/2 Second): This means the battery is almost depleted, with about 2 minutes of runtime left.
- Bad Battery Indicator (Constant Tone): A constant tone means there's an issue with the battery, which may need to be charged or is at the end of its life. Since the battery in this model is not user-replaceable, contact Schneider Electric IT (SEIT) for assistance.
