What to do if Newave UPS has fault LED?
- RRachael PittsJul 31, 2025
If the Newave UPS fault LED is on, take the following actions: * Ensure the battery connection is properly done. * Measure the battery voltage to ensure the batteries are charged or healthy. * Recharge the batteries for 8 hours if necessary. * Simulate a utility outage to verify if the UPS can provide DC back-up. * Disconnect some non-critical loads from the UPS output until the overload ceases. * Check for any short circuits between cables due to broken cable insulators and replace the cables if necessary. * Remove any objects obstructing the ventilation louvers. * Verify if the cooling fans are working properly. * Verify if the 'L' & 'N' phase of the Utility AC source has been wrongly wired or if the Ground-Neutral Voltage exceeded the limits.
