When encountering Error 02000 on an APC UPS system, the following troubleshooting steps can be undertaken:
Interpretation:
: While the error can persist after battery replacement, low battery voltage can still be a cause. One user with an SRT6KRMXLI error 02000 found the battery voltage was only 112V, far below the expected ~204V.
Reconnect the batteries, plug the UPS back into the wall outlet, and attempt to turn it on. When to Call the Professionals apc ups power system error 02000 link

Wait for roughly 30 seconds to allow the internal capacitors to discharge.
Overview APC UPS error 02000 notifies that the UPS has detected a significant power-system fault in its internal power components (inverter/rectifier/transfer circuitry). This can cause the UPS to go offline, fail to supply conditioned power, or require bypass. When encountering Error 02000 on an APC UPS
fault code as "02" or a larger number. On most APC Smart-UPS and Back-UPS Pro models, indicates an On-Battery Output Short Relay Weld Uninterrupted Power Solutions
Damage to internal components from high-voltage spikes.
: The microprocessors inside the SRT unit can experience a lockup or static memory glitch, triggering a false positive failure state. When to Call the Professionals For the most
Once the physical issue is resolved, you should clear the event log to confirm it does not reappear immediately.
The is a critical hardware fault indicating a system-level failure within the uninterruptible power supply (UPS) internal circuitry. Seen frequently on the backlit LCD screens of high-capacity APC Smart-UPS On-Line SRT models (such as the SRT5KLXI, SRT6KXLI, and SRT10KXLI), this error changes the display color to bright red. It forces the unit to drop its output voltage or shut down entirely to protect connected server racks. What Causes Power System Error 02000?
