Appendix A1: 5 to 10kVA Fault/Alarm Codes
The following Error Code Tables list the available Fault and Alarm codes shown on the
display of the 5 to 10kVA 1-Phase UPS Family.
The Buzzer will make a continuous beep or periodic beep (about 1 per second).
The Alarm/Fault LED will either illuminate Yellow for Alarm or Red for Fault. Additional
LEDs that will illuminate are Yellow Battery LED, and the Blue Inverter LED.
