What to do if my Rittal PMC12 is off for an unknown reason?

If your Rittal UPS is off for an unknown reason, start by checking any recorded error messages. You can also try pressing the keypad for 5 seconds until you hear the buzzer sound twice. Another step is to turn off the breaker of the utility input. Following these steps should solve the UPS lock problem.
