PDU Alarms
This table lists all alarms that can be generated by the InfraStruXure PDU, as displayed by the All Possible
Alarms option, with numeric variables between the < > characters. Logged alarms will display specific
numbers instead.
Alarm Condition Explanation
Input V =
Voltage Under Limit Input voltage of the phase indicated has dropped below the
configured lower limit.
Input V =
Voltage Over Limit Input voltage of the phase indicated exceeded the configured
upper limit.
Output V =
Voltage Under Limit Phase-to-neutral output voltage for phase dropped below
the configured limit.
Output V =
Voltage Over Limit Phase-to-neutral output voltage for phase exceeded the
configured limit.
Output I L=
Current Over Limit Current of output phase exceeded the configured limit.
Output I L=
Current Under Limit Current of output phase dropped below the configured limit.
Output Neut=
Current Over Limit Current on the neutral wire for the output phases exceeded the
configured limit.
Output FDev=
Freq Out of Range Frequency of the output current is above or below the range that
is configured as acceptable.
Input Transformer Temperature
Too High The temperature of the PDU transformer exceeded the normal
limit, if applicable.
Main Breaker Open
Alarm Active The Main Input Switch is Off.
Alarm Active A user-configured contact connected to the PDU monitoring unit
is reporting an alarm condition.
No UPS Input
Breaker Q1 Open The Main circuit breaker is open, and the PDU is not receiving
power from the UPS.
Branch Ckt Pos:
Current Over Limit Current on one of the poles of branch circuit breaker nn exceeded
the configured limit.
Branch Ckt Pos:
Current Under Limit Current on one of the poles of branch circuit breaker nn dropped
below the configured limit.
Fan Rotation Failure
Alarm Active There is a failure in one of the fans. The fan needs to be replaced,
if applicable.
