Connection Interfaces
L=4V/(R×i)
L- the maximum permitted distribution length
R- calculated cable resistance
i- current which
Radio 2217 uses at 36V or Radio 2218 uses at 38V

Radio power consumption [W]
Cable length [m]
Figure 18 Maximum Cable Lengths versus Radio Power Consumption (4V@36V/38V)
The power cable conductor has a wire for the 0 V conductor and a wire for the
0
48 V conductor. The wire color code for both is market dependent.
All cables must be shielded. The shielding must be properly connected both
to the power connector and to the earthing interface in the power supply
equipment, otherwise the radio overvoltage and lightning protection does not
function properly.
5.6 Position H, Grounding Interface
The radio must be earthed to protect it from overvoltage and lightning strikes.
The grounding interface on the radio accepts an M6 dual cable lug on a coated
cable.
For more information about grounding principles, refer to Grounding Guidelines
for RBS Sites.
