4. Slide the following parts over the cable shielding in order given:
rear retainer cap, large washer{s), rubber "0" ring. Either
one or two washers are included with the connector parts at the
factory. Use all of the large 512-134 washers supplied. Pur-
pose of additional washer is given in step 9.
5. Slide rear plug body over shielding. Hold rear plug body against
end of outer insulation and cut off shielding 3/16" from beveled
end of rear plug body.
6. Fan shielding out and bend back over rear plug body. Trim off
any shield wire protruding beyond beveled edge.
7. Place conical washer over shielding with flat side toward end
of plug.
8. Insert center conductor through hole in center of front plug
assembly, slide assembly back over conical washer. Thread
rear retainer cap on front plug assembly. Plug must be firm-
ly tightened so that it cannot be rotated on end of cable. The
use of strap wrenches is recommended.
9. Measure distance between front edge of rear retainer cap and
front edge of front plug assembly. This distance must not be
less than 31/32". Additional washers installed as in step 4
will increase this distance.
10. Wrap and solder the center conductor to the base of the banana
plug. Do not pull center conductor excessively tight when con-
necting to banana plug.
11. Resistance between outer connectors must be les s than one ohm.
Resistance between center connectors must be less than one ohm.
Resistance between outer connectors and center connectors
must be greater than 500 megohms.
