the ECU (see ECU instruction manual for more info).
4.3.11 Step 11 - Warning Notice
A warning notice must be placed in such a way that anyone with access to live parts is warned in advance of the
need to switch off these parts. It is imperative to verify that the power supply, measurement circuits (sense lines)
and other parts are not isolated from the network when the interface protection switch is open.
As a minimum, warning labels shall be placed:
On the switchboard (DNO panel and consumer unit) that has the PV generator connected to it;
On all switchboards in between the consumer unit and the PV generator itself;
On, or in the PV generator itself;
At all points of isolation for the PV generator
