Step 1 Install boot and slide outer ferrule onto cable as shown prior
to stripping cable.
Step 2 Strip cable jacket, braid and dielectric to dimensions shown.
See attached table for dimensions. All cuts are to be sharp
and square. Important: DO NOT nick braid, dielectric, and
center conductor when cutting. Tin center conductor using
soft solder per QQ-S-571 comp Sn 60. Avoid excessive heat
while tinning to prevent swelling of cable dielectric.
Step 3 Slightly flare out end of cable braid as so as to facilitate
insertion onto ferrule clamp nut assembly. Important:
DO NOT comb out braid.
Step 4 Install ferrule clamp nut assembly onto cable so that ferrule
portion slides under braid and insulator butts flush against
cable dielectric. Slide outer ferrule over braid and up
against nut. Make sure no slack exists in braid. Crimp outer
ferrule with tool specified in table above, keeping cable
dielectric bottomed against insulator.
Step 5 Soft solder center conductor to contact using rosin core per
QQ-S-571 comp Sn 60. DO NOT get any solder on outside
surfaces of contact.
Step 6 Screw connector body onto prepared cable termination .
Wrench tighten by holding the cable nut assembly
STATIONARY while ROTATING the connector body.
Step 7 Push body forward and into position as shown to complete
assembly.
