8. The EnerVista MM300/MM200 Setup software will notify the user when the
MM300 MM300 has finished loading the file. Carefully read any displayed messages
and click OK to return the main screen. Cycling power to the relay is recommended
after a firmware upgrade.
After successfully updating the MM300 firmware, the relay will not be operational and will
require setpoint programming. To communicate with the relay, the communication

When communications are established, the saved setpoints must be reloaded back into
the relay. See Loading Setpoints from a File for details.

features are added or existing features are enhanced or modified.
