unctionality 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 dedi-
cated 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 para-
meters 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. Ma-
naging 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 cha-
racteristics 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 re-
motely via an advanced communication system based on a RS-485 se-
rial interface. The range of optional ABB devices that can be connected
to this communication line allow you to monitor the device locally or re-
motely through an internet connection.
