Cause of the Abnormality
A temperature alarm is
generated (if the temperature
exceeds 65°C, the
EPS200-4850A will be powered
off), or the EPS200-4850A is in
the dormant state (the indicator
is on and no alarm is generated).
The EPS200-4850A is powered
off due to over-voltage or over-
temperature, or fans are faulty,
or the EPS200-4850A has no
output due to its internal faults.
