The power cable has a wire for Line (L), a wire for Line/Neutral (L/N), and a
wire for Protective Earth (PE) conductors. The wire color code for wires is
market dependent.
All cables must be shielded. The shield must be folded back over the outer
jacket of the cable and properly connected to the PSU chassis in the PSU
strain relief, otherwise the radio overvoltage protection does not function
properly.
The AC cable temperature rating must be at least 70 °C.
5.1.3.2 DC Power Interface
The −48 V DC power connection is made through a screw terminal.

For 3-wire power system, the power cable screw terminal has a wire for −48 V
conductors, a wire for 0 V, and one wire for FE (Functional Earth). For 2-wire
power system, the power cable screw terminal has a wire for −48 V
conductors, and a wire for 0 V. The wire color code is market dependent.
All cables must be shielded. The shield must be folded back over the outer
jacket of the cable and properly connected to the PSU chassis in the PSU
strain relief, otherwise the radio overvoltage protection does not function
properly.
The DC cable temperature rating must be at least 70 °C.
