Description of the Upgrade
Installation Procedure for the Upgrade
Step 17.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 semi-rigid 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. Torque these
connections to 21 in-lb.
Cables that are to be reinstalled are designated with "reuse." Part numbers
in a normal weight font are for analyzers with serial numbers
MY/SG/US5310 and below. Part numbers in a bold font are for analyzers
with serial numbers MY/SG/US5321 and above.
