Note 2: The power output is different depending on the operating condition.
Note 3: In power recovery immediately after backup operation ends, in rare cases, self-heating might occur in the
battery, activating the protection function, and the error (Fault-E12) might be displayed.
In that case, the commercial power is output as-is (charging stopped).
Then, the battery temperature drops, the error display is automatically canceled, and the charging
operation resumes.
Note 4: Different depending on the operating condition.
