Breaker
The ePDU includes branch circuit breakers that automatically trip when a power
overload is detected. The ePDU standard circuit breakers have Type C trip
characteristics. If the circuit breaker switches o the voltage rail, the lower row of the
display panel will jump to the lowest outlet number aected by the circuit breaker
error, and the upper row will display these three letters, which indicate a circuit
breaker error:
CbE
You will still be able to switch between outlets on the ePDU display panel. Outlets
aected by the error show CbE. Unaected outlets show the current and voltage
readings as described above.
To reset the breakers in the event of an overload:
On the 1U and 2U models, unclip the front molding to access the breaker(s).
On the 0U model, the breaker(s) can be accessed by lifting the hinged cover over
the breaker element.
The ePDU includes a beeper. The beeper rings if any of the circuit breakers are
tripped or if the control board temperature sensor exceeds 80 °C (176 °F).
The beeper will cease ringing when the broken circuit breaker conditions disappear or
the control board temperature sensor drops below 70 °C (158 ° F).
The temperature thresholds are factory defaults, and can be user−congurable.
It takes a maximum of three seconds for the beeper to start ringing after the circuit
breaker has been tripped.
Accuracy
Voltage (per outlet): Range 0–255V, ± 5%, 3 digits, resolution 1V
Current (per outlet): Range 0–25.5A, ± 5%, 3 digits, resolution 0.1A
