ATTENTION: Test the protective device
after any changes!
Changes to the configuration of the devices
can degrade the protective function. After
every change to the configuration you must
therefore check the effectiveness of the
protective device (see “Test Notes” on page
31).
The person who makes the change is also
responsible for the correct protective
function of the device. When making
configuration changes, always use the
password hierarchy provided by Allen-
Bradley Guardmaster to ensure that only
authorized persons make changes to the
configuration.
