Frame ground enters through the PWR-A and PWR-B terminal
blocks. Refer to Figure 27 for the location of the terminal blocks.
The terminals in the terminal blocks are listed in Table E.
Ensure the frame ground wires are long enough to go from the
wire-wrap panel to the frame ground connection. Connect the
frame ground wires to terminal F of the terminal blocks, using
appropriate sized spade lugs.
