9.3.11.2 Connection of the negative output wire (-)
Carefully follow the instructions of the previous point for the negative
pole. Pass the wire coming from the inverter through the gland “D” of
the Figure 4-3 and connect it, with the screw and nut, to the “-” bar.
The copper bar for the negative pole features a threaded bore and
M10 bolt with washers (supplied) (Ref. §Appendix A: Technical Data).
Check that the lug is tight.
9.3.12 Connection of the positive pole of the strings (+) [for max 10
strings]
The positive of pole of the strings must be connected to the terminal board
indicated by the label “STRING POSITIVE”.
Figure 9-18: Cable gland for positive strings connection
Insert the special screwdriver (Figure 9-19) into the clamp (pushing it home!) in
order to completely open the contact. Push the wire (positive pole) coming from
the string through the cable gland provided (Figure 9-18) and connect it
individually to the terminal. Then remove the screwdriver and pull on the wire to
check that it is correctly inserted. Repeat the operation for all the other wires.
Connect all the wires according to a logical sequence, S1+ with F1,
S2+ with F2, …., S10+ with F10, where F1, F2, ..., F10 indicate the
position of the fuses (on the board for positive strings, Figure 6-4
“A”, F1 is the first on the left while F10 is the last one on the right, at
the output bar to positive pole).
