Power
T phase Inverter Output Negative Power
over range
Contact service personnel.
Fault! Over Load Fault
Heavy Overload causes UPS fault
Reduce some load.

temperature exceeded
Make sure adequate space is allowed for air
vents and the fan is working. Check if the
ambient temperature is over specification.
Or contact service personnel.

demanding more power than the UPS can
supply
Reduce some load and check Output Load-
Capacity and specification
Warning! Battery Open
Battery is not connected
1. Check Battery Breaker.
2. Check if the Battery connection is well
connected.
3. Check the setting of Nominal Battery
voltage.
4. Contact service personnel if necessary.
