7.2 Making the electrical connection
Make the connection to the PV generator as well as the grid connection using the connection terminals.
Note the following cable cross-sections:
Connection Possible cable cross-section Length of insulation to be stripped off
AC home power grid 0.5 - 16 mm² with end sleeve
0.5 - 25 mm² without end sleeve 18 mm sleeve
18-20 mm
PV connection 0.5 - 16 mm² with end sleeve
0.5 - 25 mm² without end sleeve 18 mm sleeve
17-19 mm
Inverter output 0.5 - 4 mm² with end sleeve
0.5 - 6 mm² without end sleeve 12 mm sleeve
11-13 mm
Potential-free contacts 0.34 - 1.5 mm² with end sleeve
0.34 - 2.5 mm² without end sleeve 12 mm sleeve
9-10 mm
Table 4: Cable cross-sections for connection terminals
NOTE
The threaded connections should be matched to the cable cross-section.
NOTE
Only conductors and no insulation should be inserted into the connection terminals.
Individual wires or cables with end sleeves with the appropriate cross-section can be inserted
directly into the connection terminal without a tool.
Fine-strand cables without end sleeve or thin conductors will need a screwdriver (plain slot, 3.5 mm)
for connection.
To do this, insert the blade of the screwdriver into the recess provided. The cable can be inserted into
the spring terminal by pressing downwards. The spring terminal closes on removal of the screw-
driver.
