5. INSTALLATION
The inverter is connected to the photovoltaic generator via the DC terminals, and to the main AC network via the AC power terminals.
• Apply the ring terminals to the cables.
• Remove the panels protecting the connection zone in front of the terminals.
• Fix the protection wire (PE) to the connection terminal.
• Fix the wires (L1, L2, L3) to the connection terminals.
• Fix the wires (L+,L-) to the connection terminals.
• Fix the cables to the cable support guide using cable fastening brackets.
• Reposition the panels protecting the connection zone in front of the terminals.
DANGER!
Risk of electric shock from live device parts!
The inverter can be connected to a maximum of three power supplies:
1 DC cable - Photovoltaic generator power supply (separated for the three modules or shared)
2 AC cable - Power from the mains network, supplied by the electricity company
3 AC cable - Auxiliary power supply
• Before carrying out any work, make sure the electricity supply has been disconnected.
• All DC power supplies should be considered as part of the same circuit, even in the configuration with centralised multi-
string inverter. Before carrying out any work, make sure all electricity supplies have been disconnected.
