9.3.14 Connection of Strings [over 10 strings]
If more than 10 strings must be connected, they must be connected in
parallel, two by two, according to the following logical sequence, for
example:
For positive poles: (S1+, S2+ with F1), (S3+, S4+ with F2),
…..,(S19+, S20+ with F10)
For negative poles: (S1-, S2- with F11), (S3-, S4- with F12), …..,
(S19-, S20- with F20)
To connect the strings, both positive and negative poles, the instructions
in §9.3.12 and 9.3.13 respectively must be strictly followed.
In this case, the cable glands to be used must be positioned on the side
flanges (Figure 4-3)
9.3.15 Setting the DC switch (only version –S)
