Toproperly perform assembly and torquing of
connectors(cont.)
Torquingmulti-
ple inline
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. Maximizeprotection and minimize disturbancefor t he
connection that is intended to be preserved by the
protective coupler.

1. Position the cable and order the connections to
minimizethe side and end loading on the last
connection.
2. If available, use a protective connector to prevent or
reducedamage t o a connector.
Final
connection
1. Usea t orquewrench to m ake the final connection. See
Table5 on page 42 for torque wrench information.
2. Rotate 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. Position both wrenches within 90 degrees of each other
beforeappl ying force. Refer to the illustrationat right.
4. Hold the torque wrench lightly at the end of the handle.
5. Apply downwardf orceperpendicul art o wrenchhandl e;
this applies torque to connection through the wrench.
6. Tightent he connection just to the point that the wrench
breaksover. Do not overtighten the connecti on.
