CONNECTING THE PHOTOVOLTAIC GENERATOR AND MAIN AC NETWORK
TO THE POWER TERMINALS OF THE
SUNSYS PRO
R02 INVERTER
The inverter is connected to the photovoltaic generator via the DC terminals, and to the main AC network via the AC power terminals.
• Attach 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.
NOTE
Torque for the DC and AC power terminals: 20 Nm
