Notice:
1. The UPS switches-off its inverters and locks automatically into normal
service mode, if those failure codes for example occur Er06, Er07,
Er13, Er14, Er23, Er24, Er26, Er28, Er29. If the bypass voltage is
normal, the UPS switches over to bypass supply, if not the UPS stops
the output load.
2. If other failure codes occur and the bypass voltage is normal, the UPS
switches automatically over into bypass. The UPS tries 4 times per
hour to changeover to the inverter mode. If changeover to the inverter
mode fails or the same failure occurs 4 times per hour, the UPS
switches-off its inverter and blocks automatically. The several error
messages and counting times will be completely canceled, if the UPS
switches over to inverter mode and the error messages are more than
one hour ago.
