Terminal block structure
As illustrated in Figure 2-8, 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.
