Figure 4-22 Terminal block structure diagram

As illustrated in Figure 4-22, the two leftmost input terminal blocks are DC input

terminal blocks. Next to them are two air switches, each of which has a through-current

capacity of 63A. On the rightmost side are 9 terminal blocks, 6 of which are BGND

terminal blocks and the rest are PGND terminal blocks.
