quadralink istruction manual - med cap.pdf

Two different manuals exist for the QUADRALINK Radio:

1. The instruction manual (IM), which is shipped with everyrack, explains how to install, operate and maintain the radio.

2. The system application information (SAI), which is availableon request, provides system design information.

This section is a quick reference to help you locate and identify theunits and modules of the Quadralink radio. The number in thecircles in the following illustrations corresponds to a descriptionof the unit or connector in the following tables.

!Never connect hazardous voltages to theQuadralink radio or the optional front accesspanels. Application of an electromotive forcepotential greater than 60 volts peak referenced toground could cause injury to personnel or evendeath. System design or installation techniciansshould ensure such voltages will not arise from anysource, including but not limited to, lightning,incorrect wiring, or fault conditions.

NOTE

If the radio rack has an optional front access interfacepanel, see appendix B 'OPTIONAL FRONTACCESS PANELS CONNECTION AND USE'for connection information.

NOTE

If the radio is used in a 1:N configuration, refer theSAT COM 30 technical handbook to identify the unitsand modules of the 1:N switch.
