Make the Final Connection Using a Torque Wrench
1 Use a torque wrench to make the final connection. The table below provides
information about the torque wrench. Using the torque wrench guarantees
that the connection is not too tight, preventing possible connector damage. It
also ensures that all connections are equally tight each time.
2 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). In all situations, however, it is recommended that you
use an open-end wrench to keep the body of the device from turning.
3 Position both wrenches within 90 degrees of each other before applying force.
Refer to Figure 2-1 . Wrenches opposing each other (greater than 90 degrees
apart) will cause a lifting action which can misalign and stress the connections
of the devices involved. This is especially true when several devices are
connected together.
