Installation Procedures
The washer must be installed with the smooth (rounded) surface facing the RF
connector; otherwise, the RF connectors may bind when the screws are tightened. To
further reduce the chances of binding, ensure that the mounting flange on each RF
connector is straight prior to installation (when viewed from the long side of the
connector). Straighten the flanges if they are observed to be bowed.
Refer to Section 2.7 Electrical Connections for details about how to wire the connectors.
