6. Connect the GND post on the removable frame to the central ground
bus. The central ground bus must connect to the grounding electrode
system through a grounding electrode conductor. The interface is
shipped to you with a wire connecting the post to the stationary
frame and another wire connecting the post to the GND terminal of
the terminal block. When you ground the post on the removable
frame, you thereby also ground the stationary frame and the
power-supply board. (Figure 4.11)
7. Connect the L2/N terminal to the low side of the transformer
supplying the AC power (Figure 4.11).
8. Connect the L1 terminal to the high side of the transformer supplying
the AC power (Figure 4.11).
9. Install the supplied terminal cover over the terminal block.
WARNING: Do not leave these terminals exposed. Exposed
power terminals could cause you to receive a dangerous
electrical shock.
