4.APsystems Microinverter System Installation
4.3.8 Step 8 - Complete the APsystems installation map
a. Each APsystems Microinverter has 2 removable serial number labels.
b. Complete installation map by sticking ID label of each microinverter at the right location.
c. The second serial number label, could be stuck on the solar module frame, which could help later to
confirm the position of the microinverter without dismantling the PV module
Figure 10
①. The layout of the microinverters' serial numbers installation map is only suitable for typical installation
②. Installation Map is available in the last page appendix of this manual.
③. Use ECU_APP (available in the EMA Manager APP) to scan the serial numbers on the map when setting
up the ECU (see ECU instruction manual for more info).
4.3.9 Step 9 - Warning Notice
A warning notice must be placed in such a way that anyone with access to live parts is made aware 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
