Step-by-Step Troubleshooting Guide

Follow these proven steps when your APC UPS shows no status:

• Check physical connections:
  • Verify AC input and output cables
  • Inspect battery terminals for corrosion
• Perform a hard reset:
  1. Disconnect all loads
  2. Unplug from wall outlet
  3. Wait 5 minutes before restarting
