To start communicating with the relay go to “
Communication>Computer>Computer settings
” section in the main
EnerVista 650 Setup menu.
Safety instructions must be followed before connecting the computer to the relay. Safety instructions are detailed in section
1.1.3. Connect the relay ground terminal and the communicating computer to a good grounding. Otherwise, communication
may not be viable, or even, in worst cases, the relay and/or the computer could result damaged by overvoltages.
For on-line working, previously ensure that all relay communication parameters, such as baudrate, slave ModBus address,
etc., match the computer settings.
