PERATIONS
Start up the system as follows:
•
Ensure that the MICRO inverters and photovoltaic modules have been correctly installed.
•
Arm the main AC disconnector (downstream from the system) and any other possible
isolator switches.
At this stage, we recommend not securing the CDD to the wall because the final installation position
might need to be re-evaluated based on the strength of the signal.
