It should be cut to such a length that it will reach frorn the farthest jack to the farthest terminal in a partictrlar run and then doubled back and laced into the cable. (b) TERN{INAL BOARDS.-There are two methods of mounting the terminal boards as illustrated in figures 2-10 and 2-I4. Wiring is as illustrated. 1. FRONT PANEL MOUNTING (Fisure 9-10 ).-The terminal boards on the equipment as shipped are motrnted on special size B panels AN Typ" I-242/G, which fit into regular rack mountittg space. If the front panel space is not required for some other Figure 2-ll.

In clamp'tg tt;,. '',',,irir,l4,, be sure to place the clamps in such o ptrsiricr. ti,, il.e -"th jre boards may be pulled out throtrgh the front , wiring corlnected. 2. SIDE PANEL MOr NTII.IC D't,Q'trr: 2-1ln).-should additional front panel mounting spat' ' be required, the terminal strips may be mounted the side of the Cabinet opposite from the side whicl: carries the convenience outlet strip (right hand looking from the rear). The mountittg is accomplished by drill' ing and tapping appropriate holes in the rear vertical corner angle of the Cabinet. One of the movable vertical channels is installed in such a position that it may be drilled and tapped to support the opposite end of the panel. This type of mounti.tg is possible only if the components mounted on the front panels do not protrude more than 4L,/2 inches beyond the rear of the front panel. 3. WIRINC THE TERMINAL BOARDS.- The terminals on the boards are numbered in pairs. These numbers correspond with the pairs of sim" Y numbered jacks on the jack strips. Figure 2-40 's a typical connection diagram. The actual connections will of necessity be determined by the needs of the individual station. In making the connections on the terminal strip end of the internal wiring, Thomas and Betts Grounding Ferrules #200-30006 or the equivalent are used in all cases. These ferrules are installed as illustrated in figure 2-L5. After the spade lugs are installed on the ends of the conductors, ring out all circuits and clip the spade l.rg rvhich connects to the right hand jack of a particular lair, thus making it possible to maintain polarity. The terminal board illustrated in figure 2-L6 is wired using this method. Solder on a piece of # 14 AWG tinned bus wire as shown in figure 2-L6 and solder the groundittg braids to it. It is not necess ary to ground the panel itself as the paint he.s been omitted around the mountittg screws to make it self groundittg. Remember to leave enough cal,'Ie to allow the terminal boards to be pulled out for servicing with the wiring connected. (c) AF SELECTOR SWITCH WIRING.-Referring to figure L-I7, it can be seell that the spacing between the terminals is very close. Tl ' ends are made up using the Thomas and Betts G,r"ounding Ferrules #200-30006 or equivalent as shown in figure 2-15. The shield is not grounded on this end. l. prcce of #L radio grade spaghetti L/2" long is slipped qvet the grounding ferrule to prevent it from trtalrirtg ':lectrical contact with the terminals, thus causi., ,; a . lrt circuit. A piece of #9 radio grade spa.tahe{tr l" ltlng is then slipped over each conductrr and tlre 1.; *rle lugs which come secured to the terminals are c,,,,:{':. ir t ea,. h frFiK$rhlAt
