5.1.4 Electrical wiring 
The electrical wiring must be done using appropriate cables thus assuring the equipment responds to 
the electromagnetic compatibility standards. 
The cable terminates to flying connectors which have to be connected to the corresponding 
connectors on the equipment front. 
Position and pin–out of the equipment connectors are available in the appropriate section in the 
following of this document. 
5.1.5 Unit grounding 
The device is equipped with a ground nut located on the rear panel of the device and identified by a 
 label. This nut must be used for a direct connection of the device to the site grounding, even if the 
device is included in a cabinet. All antenna cables and DC power cabling should be properly grounded 
and lightning protected. Failure to provide proper lightning protection may result in permanent damage 
to the radio equipment.
