3.9.7 Remote shutdown by the grid operator and rapid shutdown
"Teledistacco" (Italy)
This configuration meets both the requirements in accordance with
VDE-AR-
N-4105
and the requirements for a
rapid shutdown ("Teledistacco") for
Italy in accordance with CEI 0-21
.
To allow a rapid shutdown of the generating plant by the grid operator
(RAPID SHUTDOWN) via an external device used for control purposes, the
connections "COM1" or "COM2" must be connected as described below.
Assignment of contacts for rapid shutdown
Assignment of contacts corresponds to the conductor number of the
RJ45 plug.
For external fas shutdown, lines 3 and 8 of COM1 or COM2 are connected (e.g. with an
external relay). The following applies:
•
Relay closes:
Inverters connected to the bus disconnect from the grid.
•
Relay opens:
Inverters connected to the bus connect to the grid in normal operation.
