🔧 Troubleshooting Guide

1. No output: Verify 24VDC input, battery wiring and deep-discharge lockout
2. PROFINET communication failure: Confirm IP address, check RJ45 cabling and view PN status via built-in web page
3. Shortened backup time: Battery aging; check battery SOH (State of Health) via IQ diagnostic page
4. Charging failure: Mismatched battery type, abnormal temperature or loose wiring

Application Case: Phoenix QUINT4 DC-UPS (including 2907079 PROFINET version)

Core advantages: DIN rail 24VDC uninterruptible power, IQ smart battery management, industrial bus communication (PN/EIP/EC/USB), battery SOH diagnosis, cold start and controlled safe shutdown; ideal for EtherCAT / PROFINET systems
