3.3.3 Disconnection Method
Step 1
Support the connectors to prevent any kind of force which may result in distortion, shaking or
bending.
Step 2
Use the open-end wrench to prevent the connector body from rotation.
Step 3
Use another wrench to loosen the connector nut.
Step 4
Rotate the connector nut by hand to complete final disconnection.
Step 5
Horizontally separate two connectors.
3.3.4 Use of Torque Wrench
The use of the torque wrench is shown in Fig. 3-24. Pay attention to the following items.
Check whether the torque of the torque wrench is set properly before use.
Ensure that the angle between the torque wrench and the other wrench (used to support the connector or
cable) is less than 90° before applying force.
Carefully grip the handle end of the torque wrench, and apply force in the direction vertical to the handle to
reach the break point of the wrench.
Torque direction
Step 2
As shown in following fig below, horizontally move two connectors to make them connected
smoothly. Tighten the connector nut by means of rotation (do not rotate the connector). Avoid
relative rotation of connectors during connection.
Step 3
As shown in following fig, complete the final connection by tightening with the torque wrench.
Note that the torque wrench must not be beyond the initial break point. Use the auxiliary
wrench to prevent the connectors from rotation.
