Solutions
• Check if battery cables are connected properly
• Check if battery breaker or fused are open
• Check if batteries are damaged
Manual bypass housing open, UPS will transfer will transfer to static bypass
and will impede inverter operation mode.
• Check if EPO is closed correctly
• Check if EPO is activated manually
UPS mains input is abnormal.
•
Check if mains input is normal
•
Check if mains input voltage and frequency is over the working range
• Check if mains input breaker or external input breaker is opened
Please recover mains input power, otherwise output will be shutdown if bat-

Check the load and remove some non critical load until the load is be-
•
low 95%
Bypass overload and timeout, UPS will shutdown output.

terruption if manually transferred to bypass or inverter faults.
Main, battery, inverter, or bypass transfer occur 5 times in 1 Hour.
Load is abnormal or output breaker is shorted.
Check load for short and eliminate if any
•
Check output breaker for short
•
After verifying no short is present at output, restart UPS.
DC BUS over/under voltage, or shorted/opened IGBT. Restart UPS, if
issue still persist contact DSPM.
Inverter voltage is abnormal, or inverter IGBT is shorted/opened. Re-
start UPS, if issue still persist contact DSPM.
Rectifier heatsink is reading above maximum threshold.
Check if fans are working properly
