■ Wiring the EX-2474 system cable
q Loosen the four bolts using a hex head wrench on
the bottom of the scanner unit, and open the unit.
w Loosen the nut on the scanner unit and pass the
system cable through the nut and sealing tube.
e Loosen the six screws on the IF unit. Then pull and
remove the cover.
r Insert the IF cable (black and white) connector to
the IF unit connector J3. (*1; Be sure to follow the
following diagram carefully)
t Replace the IF unit cover to the proper position,
then tighten the nine screws.
y Connect the shielding wire to the ground plate with
the screw as shown in the diagram.
u Clamp the system cable with the ferrite core at-
tached near the sealing connector. Be sure to clamp
it tightly.
i Connect the power cable (black and red) end to the
power unit connector. (*2; Be sure to follow the fol-
lowing diagram carefully).
o Tighten the sealing-nut, then replace the radome
cover over the scanner unit.
DO NOT stretch the system cable too much, other-
wise miss contact of the connector may occur.
!0 Tighten the four bolts on the bottom of the scanner
unit.
• The four projections around the circumference of
the radome cover show the positions of the bolt
receptacles.
CAUTION: DO NOT cut the supplied system
cable.
