Description of the Upgrade
Installation Procedure for the Upgrade
Step 27. Install the Test Set Cables
Follow instructions carefully when making cable connections, especially
wire harness connections. Incorrect connections can destroy components,
resulting in additional customer costs.
Be careful not to damage the center pins of the semirigid cables. Some
flexing of the cables may be necessary but do not over-bend them.
Use a 5/16-in torque wrench set to 10 in-lbs on all cable connections
except the front and rear panel cable connectors. On the bias tees use a
5/16-in torque wrench set to 9 in-lbs. On the bulkhead connectors, use a 9
mm nutsetter or open end torque wrench set to 21 in-lb.
