Yes. The back cover of the device must be opened and the safety precautions must be followed. Please see the linked document for details.

Is the meter hardware locked?  You can look on the COM card for the revenue sealing jumper.

Another way to determine if it is hardware locked is that ION Setup will show a message saying some settings can't be changed when attempting to view the display modules.

Yes, it is hardware locked.

How can we remove hardware lock? Does it involve opening the back-cover of the meter?
