APsystems DS3 series User manual
4. APsystems Microinverter System Installation
4.3.10 Step 10 - Complete the APsystems installation map
a. Each APsystems Microinverter comes with 2 removable serial number labels.
b. Complete the installation map by affixing the ID label of each microinverter at the appropriate location.
c. The second serial number label can be adhered to the solar module frame. This label will assist in later
confirmation of the microinverter's position without the need to dismantle the PV module.
①. The arrangement of the microinverters' serial numbers in the installation map is designed for
standard installations.
②. The Installation Map can be found in the appendix on the last page of this manual.
③. When configuring the ECU, use the ECU_APP (accessible through the EMA Manager) to scan the serial
numbers on the map (refer to the ECU instruction manual for further details).
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
