20.Route the signal cable beneath the lower left side of the terminal board fixing
plate for the RTB-801. Shorten conductors of the signal cable considering their
locations on the RTB-801.
Coaxial cable
2C-2V
21.Shorten the shield considering the distance to the ground terminal on the left
side of the scanner unit chassis. (See Figure 2-13 for location.) Attach the
crimp-on-lug FV5.5-4 (ø4, yellow) to the shield.
22.Remove approx. 6 mm of the vinyl insulation from the end of each conductor
and fix the crimp-on lug FV1.25-M3 (Red) to each conductor. As shown in Fig-
ure 2-14, fold back the coaxial cable four times and attach the crimp-on-lug
FVD1.25-3 (ø3, red). Attach the crimp-on-lug FVD1.25 (ø3, red) to the shield.
23. Tighten the clamping gland, and then seal the cable gland with putty.
24.Fasten the shield to the ground terminal on the scanner unit chassis.
25.Connect conductors to the terminal board RTB-801 referring to the intercon-
nection diagram.
When the length of the signal cable is more than 150 m, remove the solder at
terminal Nos. 24 (red) and 26 (black) on the DJ-1 connector. (#24 and #25 are
spares.). Fasten the wires as shown below.
