Functionality and components of the equipment

Configurable relay

The inverter is equipped with a configurable switching relay, which can be used in different operating configurations that can be set in the dedicated menu. A typical example of application is the activation of the relay in the event of an alarm.

Remote switch-on/switch-off

This command can be used to turn off/turn on the inverter via an external (remote) command. This functionality must be enabled in the menu and when active, switching 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 control for switching on/off.

Reactive power feed into the grid

The inverter is capable of producing reactive power, and then feeding it into the grid through this connection, by setting the phase factor. Managing the input can be controlled directly by the grid company via a dedicated RS485 serial interface or set by the display or through the configuration software, Aurora Manager TL. Power feeding modes vary according to the country of installation and the grid companies. For detailed information on the parameters and characteristics of this function, contact ABB directly.

Limiting the active power fed into the grid

The inverter, if enabled and set using the display or the Aurora Manager configuration software, can limit the amount of active power fed into the grid by the inverter to the desired value (expressed as a percentage).

Data transmission and control

The inverter or a network of several inverters, can also be monitored remotely via an advanced communication system based on a RS-485 serial interface. The range of optional ABB devices that can be connected to this communication line allow you to monitor the device locally or remotely through an internet connection.
