CAUTION
Follow instructions carefully when making cable connections, especially wire harness
connections. Incorrect connections can destroy components, resulting in additional customer
costs.
CAUTION
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.
CAUTION
Use a 5/16-in torque wrench set to 10 in-lbs on all cable connections except the front and rear
panel bulkhead connectors. On these, use a 9 mm nutsetter or open end torque wrench set to
21 in-lb.
