What to do if my East EA901P shows fault code 50-54 indicating an overload?
If the East UPS displays a fault icon, sounds an alarm, and shows fault code 50-54, it indicates an overload. Check the load level, disconnect non-critical equipment, and recalculate the total capacity to reduce the load on the UPS. Also, inspect the connected equipment for any faults.
Why is the backup time so short on my East EA901P UPS?
If the backup time of your East UPS has become short, there are several possible causes. First, the battery may be undercharged; keep the UPS battery recharging for more than 3 hours. Second, the UPS may be overloaded; check the load level and disconnect any non-critical equipment. Finally, the battery may be old and its capacity diminished; consider replacing it.
