Notes:
.
1. Safety/Case Ground - Wire to green screw at top center of rear terminal area.
2. Ground Bus - An external, user-supplied ground bus can ease connection of multiple grounds, particularly
when twinaxial cable shields are to be grounded.
3. Terminals 6, 9, 18, 21, 24, 34, 40 and 42 are electrically connected. Use the terminals that allow the best wire
routing and the least stress on components, such as range resistors.
