Table .5 Alarm list displayed in the LCD panel.
˙
Alarm 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.
˙
Alarm 17: If battery test (automatic or manual) is finished
unsuccessfully, this alarm will appear.
˙
Alarm 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.
