How the Automatic Management Function Works
This setting is configured on PDU (on page 94).
After enabling the automatic management function:
When the total number of managed sensors and actuators has not reached the upper limit yet, Legrand PDU
automatically brings newly-connected environmental sensors and actuators under management after
detecting them.
Legrand PDU can manage up to 32 sensors/actuators.
After disabling the automatic management function:
Legrand PDU no longer automatically manages any newly-added environmental sensors and actuators, and
therefore neither ID numbers are assigned nor sensor readings or states are available for newly-added ones.
You must manually manage new sensors/actuators. See Peripherals (on page 116).
Time Units
If you choose to type a new value in the time-related fields, such as the Inrush Guard Delay field, you must
add a time unit after the numeric value. For example, you can type '15 s' for 15 seconds.
Note that different fields have different range of valid values.
Time units:
Unit Time
ms millisecond(s)
s second(s)
min minute(s)
h hour(s)
d day(s)
Inlet
You can view all inlet information, configure inlet-related settings, or reset the inlet active energy on the Inlet
page. To open this page, click 'Inlet' in the Menu (on page 84).
Inlet thresholds, once en
abled, help you identify whether the inlet enters the warning or critical level. In
addition, you can have Legrand PDU automatically generate alert notifications for any warning or critical
status. See Event Rules and Actions (on page 184).

Sensors in warning or critical states are highlighted in yellow or red.
