Remarks:
1. When one of the Er06, EPO, Er23, Er24, Er28, Er32 ,or Er33 error message occurs, the UPS will have no
output and lock itself immediately.
2. If the bypass voltage is normal(within specs), but one of the Er01, Er02, Er03, Er05, Er13, Er14, Er20, Er22,
Er26, Er29 or Er30 error message occur, the UPS will transfer to Bypass loop and lock itself.
3. If the bypass voltage is normal(within specs), one of the Er04, Er08, Er09, Er10, Er11 or Er12 error message
occurs, the UPS will transfer to Bypass loop, then try to transfer back to Inverter mode automatically. If
the symptoms happen 4 times in one hour, the UPS will lock itself; otherwise, the error messages and the
times of the error messages will be clear and reset automatically.
4. If the Er16, Er17, Er21, Er27, Er31 or Er34 error message occurs, the inverter of the UPS will have no output
and the user is prohibited to turn on the UPS from the front panel.
