Why CyberPower PR1500 UPS will not turn on?
- ZzbergJul 26, 2025
If your CyberPower UPS won't turn on, first turn the UPS off, wait 10 seconds, and then turn it back on. The on/off switch is designed this way to prevent damage from rapid cycling. Also, ensure the unit is connected to a 110/120v 60Hz outlet. If these steps don't work, contact CyberPower Systems about replacement batteries or for assistance with a mechanical problem.
