58 Legrand PDU User Guide
You can use the LCD display to view the Legrand PDU information and even switch an outlet. It consists of:
A dot-matrix LCD display
Four control buttons
Zero U models automatically adjust the orientation of the content shown on the dot-matrix LCD display after
detecting the direction in which the PDU is installed. 1U and 2U models do NOT adjust the content's
orientation.
Note: All dot-matrix LCD display diagrams illustrated in the User Guide are for Zero U models. Your
dot-matrix LCD may look slightly different if it is on a 1U/2U model.
Automatic and Manual Modes
After powering on or resetting the Legrand PDU, the front panel LCD display first shows a dark screen, then
Legrand logo and finally enters the automatic mode.
Automatic mode without alerts available:
In this mode, the LCD display cycles through the inlet information as long as there are no alerts.
If overcurrent protectors are available on your Legrand PDU, the display cycles between both the inlet and
overcurrent protector information.
Note: You can make a Legrand PDU with overcurrent protectors show the inlet information only in the
automatic mode. See
