Table .6 Alarm list displayed in the LCD panel.
 Screen 4.16: The temperature of battery cabinet (in case of separate battery cabinet) or battery
place (in case of battery are located inside the UPS) is higher than 40ºC.
 Screen 4.17: If battery test (automatic or manual) is finished unsuccessfully, this alarm will appear.
 Screen 4.18: Two possible reasons:
During the unit start up, a message appears
indicating that the battery switch can be
switched ON. After some period of time
without switching ON, this alarm appears
When the unit is running under normal
conditions, and the battery switch is
switched OFF.
 Screen 4.19: When the mains is connected during the start up, a phase rotation error is detected
and the start up procedure is inhibited.
 Screen 4.20: When the bypass is connected during the start up, a bypass phase rotation error is
detected and the start up procedure is inhibited.
 Screen 4.21: This alarm appears when in any phase, the rectifier input voltage phase to neutral is
out of the set margins (+15%/–20% by default) or the rectifier input frequency is out of the set
margins (± 0,5Hz by default). Then the rectifier is shut down.
 Screen 4.22: This alarm appears when any IGBT in the rectifier side, desaturates the number of
times programmed by display (50 by default).
 Screen 4.23: This alarm appears when there is a (*) DSP Internal Error in the rectifier module,
shutting down the rectifier immediately. There will be 3 more retries before the rectifier blocking.
 Screen 4.24: When a mains phase rotation error is detected and under these conditions the
