To properly perform assembly and torquing of
connectors (cont.)
Torquing multi-
ple i nline
connectors
1. If starting from a fully disassembled state, order the
connections so that they are assembled from the outside
moveable portions toward the inward (stationary)
portions. Disassemble from the inside outward.
2. If starting from a partially disassembled state, such as
with a protective coupler, leave subassemblies intact.
3. Maximize protection and minimize disturbance for the
connection that is intended to be preserved by the
protective coupler.
Joining two
stationary
connectors with
a semi-rigid
coaxial cable
1. Posit ion t he cable and order the connections to
minimize the side and end loading on the last
connection.
2. If available, use a protective connector to prevent or
reduce damage to a connector.
Final
connection
1. Use a torque wrench to make the final connection. See
Tabl e 5 on page 42 for torque wrench inf ormation.
2. Rotat e only the connector nut that you are tightening. If
necessary, use an open-end wrench to keep the body of
the device from turning.
3. Posit ion both wrenches within 90 degrees of each other
before applying force. Refer to the illustration at right.
4. Hold the torque wrench lightly at the end of t he handle.
5. Apply downward force perpendicular to wrench handle;
this applies torque to connection through the wrench.
6. Tighten the connection just to the point that the wrench
breaks over. Do not overtighten the connection.
