Loading setpoints from a file
An error message will occur when attempting to download a setpoint file with
a revision number that does not match the relay firmware. If the firmware has
been upgraded since saving the setpoint file, see Upgrading setpoint files to a
new revision on page 22 for instructions on changing the revision number of a
setpoint file.

are not identical, see Upgrading setpoint files to a new revision on page 22 for details
on changing the setpoints file version.
3. Right-click on the selected file and select the Write Settings to Device item.
