5 SS 2, SECTON NSTALLATON 3.01 For information on apparatus mountings and relay racks, refer to Section Fig. 4 through 13 show panel and connecting block layouts for 601A, 602A, and 603A panels When a 424A KTU (19-code circuit) is used in the 602A panel, an additional 422B KTU, 69D apparatus mounting, an A25B connector cable, and a 66B4-25 connecting block are required. (See Fig. 9 for layout.) Note: A separate 421A KTU must be provided in a 69D apparatus mounting if interrupted signal for intercom differs from that provided by existing panel interrupter (see Fig. 8 and 9 for layout) 3.04 Panel and connecting block layouts are shown for optional features such as preset conference, DSS, and long line circuits. These configurations require additional 66-type connecting blocks, connector cables, 69-type apparatus mountings, and KTUs. (See Fig. 6, 7, 10, 11, and 12, whichever apply, for layouts of these options.) 3.05 nstall panels on relay rack or 16-type apparatus mountings in the usual manner. A 99A (MD) or 99B bracket must be used when installing the panels on a relay rack nstall 69-type apparatus mountings (if required) nstall 66B4-25 connecting blocks and stencil each block as required (Fig. 4 through 12). 601A and 602A Panels 3.08 nstall A25B connector cables from panels to connecting blocks. Note: A75A and A50B connector cables can also be used to connect 601A and 602A panels, respectively, to the connecting blocks. When using the A 75A connector cable, the conductors in the BL-W, 0-W, and G-W binders are terminated on connecting blocks 1, 2, and 3, respectively. When using the A50B connector cable, terminate the conductors in the BlrW and 0-W binder on connecting blocks 1 and 2, respectively After all other panel connections have been made, use 20-gauge strapping wire to terminate power leads to connecting block on the panel. Strip ends of wire and be careful to avoid shorting adjacent terminals; then, connect power leads to the power supply provided for the 584 type panels nstall key telephone units Make certain fuses are properly installed and not blown after power leads have been terminated. 603A Panel 3.12 Terminate free end of cable stub on connecting block located on 601A (Fig. 15) or 602A (Fig. 23) panel.
