Meaning
Input line voltage is out of the specified
range.
Input line frequency is out of the specified
range.
Input line power conductors are not wired
in a proper phase sequence.
The converter interlock is active.
The output load current has exceeded
105% of the rated current.
The output load current has exceeded
110% of the rated current.
The output load current has exceeded
125% of the rated current.
The output load current has exceeded
150% of the rated current.
Short time over-current has been detected
during the inverter operation.
Bypass line voltage is out of the specified
range.
Bypass line power conductors are not
wired in a proper phase sequence.
Bypass line frequency is out of the
specified range.
Transfer to the bypass is not available due
to bypass abnormality.
The emergency stop was activated by the
EPO switch or an external contact.
The UPS could not transfer to the bypass
because the inverter output was not
synchronized to the bypass.
The UPS could not transfer to the bypass
because external "generator operation"
signal indicates a backup generator is in
operation.
