later use.
5. Remove the screws securing the top internal safety shield panel. Remove the panel to gain access to the
TB1 and TB2 terminal blocks, X-Slot communication bays, and the top conduit landing plate (see
Figure 86). Retain the hardware for later use.
6. If installing interface wiring from the bottom of the cabinet, proceed to Step 7; otherwise, proceed to
Step 8.
