How to respond to a battery high-temperature alarm on an Eaton 9395 / 93PM UPS
Battery high temperature accelerates capacity loss. Check the room HVAC, verify individual battery temperatures, and schedule an impedance test to identify weak cells.
How to fix inverter output voltage distortion on an Eaton 9395 / 93PM UPS
Output voltage distortion above 5 percent THD can reset sensitive pharma instrumentation. Check the output filter capacitors and inverter IGBT driver boards.
How to diagnose a static bypass failure on an Eaton 9395 / 93PM UPS
A static bypass fault means the SCR assembly or bypass synchronization has failed. The load is unprotected. Identify the root cause before transferring back to inverter.
