The Revelation PDU is shipped with one user profile built in. This is the Admin profile, which
was used for the original login. This profile has full system and outlet permissions, and should be
reserved for the system administrator. This profile cannot be modified or deleted.
All users must have a user profile. The profile specifies a login name and password, and contains
additional (optional) information about the user. It also assigns the user to a User Group, and the
User Group determines the user’s system and outlet permissions.
If you choose, you can refrain from assigning some or all users to a User Group, and instead
assign their system and outlets permissions on an individual basis.
Note: By default, multiple users can log in at the same time using the login name from the same
profile. You can change this so only one user at a time can use a specific login. This is done by
selecting Device Settings  Security and checking the check box labeled Enable Single Login
Limitation.
