2. Use another open-end wrench to loosen the connector nut.
3. Complete the separation by hand, turning only the connector nut.
4. Pull the connectors straight apart without twisting, rocking, or bending
either of the connectors.
Using a Torque Wrench
Use a torque wrench to make a final connection. Table 3-1 provides
information about the torque wrench recommended for use with the
verification kit. A torque wrench is not included in the verification kit. Refer to
Table 6-2 for part number and ordering information.
Using a torque wrench guarantees that the connection is not too tight,
preventing possible connector damage. It also guarantees that all connections
are equally tight each time.
Prevent the rotation of anything other than the connector nut that you are
tightening. It may be possible to do this by hand if one of the connectors is
fixed (as on a test port). However, it is recommended that you use an open-end
wrench to keep the body of the device from turning.
1. Use the torque wrench supplied with your kit to make the final
connections.
2. Rotate only the connector nut when you tighten the connector.
In all situations, use an open–end wrench to keep the body of the device from
turning. Position both wrenches within 90 degrees of each other before
applying force (see Figure 3-8 on page 3-15 ). Wrenches opposing each other
(180 degrees apart) will cause a lifting action (see Figure 3-9 on page 3-15 ).
This lifting action can misalign, and stress the connections of the devices
involved. This is especially true when several devices are connected together.

Do not pre-tighten the connector nut so much that there is no rotation of
the nut with the torque wrench. Static friction must
not
be present during
torquing.
