of the display with the circuit breaker mounted on its side, the display is configurable to
rotate 90 degrees left or right.

display used to control the information shown
on the display and to select configuration
options:

the menu display screen or increase an
adjustment value.

Each trip unit style has configurable settings for protection and other features. They can
be configured using either the front panel or by using PXPM software. Details regarding
the available protection settings for each frame are found in Section 9: Available protection
settings.
