The unit can be decommissioned by turning off power to the unit and disconnecting the wires to it.
Files can be cleared after uninstalling the EnerVista software or UR device, for example to comply with data security

On the computer, settings files can identified by the .urs extension. To clear the current settings file, create a default
settings file, write it to the relay, then delete all other .urs files. For the existing installation, upgrading the firmware

You cannot erase directly the flash memory, but all records and settings in that memory can be deleted. Do this using the
