WARNING
Risk of electrocution!
Before starting work on the general electrical cabinets inside the building, you must disconnect
the power supply entering the electrical cabinets and isolate the photovoltaic system to avoid
double feeding and possible electrical shocks.
In case of emergency, the AC power supply to the inverter should be isolated by switching off
the magneto-thermal switch located in the AC electrical cabinet and the DC supply at the main
DC disconnection point located in the DC electrical cabinet or in the inverter itself. All persons
working on the DC wiring of a photovoltaic system must be qualified to work with such systems
and be fully familiar with the voltages present in the system.
Failure to follow the above instructions may result in death or serious injury!
IMPORTANT: The DC cables connected to a PV module or strings are live at all times during the day
and night. Therefore, DC cable runs should be as short as possible and cables should be carefully routed
and secured.
Please consider the following precautions:
Do not direct artificially concentrated sunlight at the panel.
