This button is only present if you have placed the XT2640 into the remote state via an interface. If you press this button it returns
the XT2640 to the local state if it is able (the interface can also set the remote with lockout state which disables this button).

POWER
BUTTON
If you press this button it will turn off the XT2640.
Note:
This button is present on all screens and must be pressed continuously for at least ¾ second for it to take effect.
If configured for the XT2640 to be continuously powered then the XT2640 will immediately power back on again, so
performing a reboot action.
If this button is colored red when pressed then this indicates that there is too much current flowing through the XT2640
and the user should remove this current prior to turning off the XT2640.
