Use, Maintenance, and Care of the Devices
Connections
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.
Position both wrenches within 90 degrees of each other before applying force. See
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.
