Cabling
Before connecting the cables to the solar inverter, use a multimeter to check that the cables to be
connected are not live.
Cables coming from photovoltaic panels will be active while panels are lit.
5.2.1
Earth connection
The solar inverter has an earth connection terminal to which all the inverter's metallic parts are
connected. This connection terminal must be connected to earth. Remember to earth the PE busbar.
See Table 5-1 on page 18.
5.2.2
Connection to mains
The terminals of the power supply can be reached through the bottom part of the equipment. The
solar inverter has three connection terminals, to which mains cables are connected.
Run the cables through the opening on the bottom of the cabinet. See Figure 5-5.
