6. After the Boot 2 upload is completed, the EnerVista 8 Series Setup software requests
the user reboot the relay. After the Boot 1 upload is completed, the EnerVista 8 Series
Setup software again requests the user to reboot the relay.
Make sure to reboot the relay first and then press the OK. Not the other way around.
7. Wait for the Comms upload process to complete.
8. Wait for the Mains upload process to complete.
9. The EnerVista 8 Series Setup software notifies the user when the 845 has finished
loading and notifies the user to Cycle power to the relay to complete firmware
update.
After successfully updating the 845 firmware, the relay is not in service and requires
setpoint programming. To communicate with the relay, the communication settings may
have to be manually reprogrammed.
When communications is established, the saved setpoints must be reloaded back into the
relay. See Loading Setpoints from a File for details.
Modbus addresses assigned to features, settings, and corresponding data items (i.e.
default values, min/max values, data type, and item size) may change slightly from version
to version of firmware.
The addresses are rearranged when new features are added or existing features are
enhanced or modified.
