2 - Characteristics
- Remote switch-on/switch-off
This command can be used to switch off/switch on the inverter via an
external (remote) command.
This function must be enabled in the menu and when active, switch-
ing on the inverter, besides being dictated by the presence of normal
parameters which allow the inverter to be connected to the grid, also
depends on the external command for switching on/off.
