DIB-500 R4.1 Requirements concerning the electrical system
Voltage supply
32 Site Requirements 90DIB500R41SR_FCC02 – 99.1
5.1.2 Cable specifications for the data and RF cables
The following table lists all the suitable cable types and their specifications.
5.2 Voltage supply
Each equipment rack (apart from the equipment rack(s) of the cavity variant) of the
DIB-500 R4.1 features a connection panel, via which the integrated components are
supplied with voltage and grounded.
Table 5.3 describes the required number of voltage supply connectors on site as a fac-
tor of the voltage supply and the number of carriers. Depending on the voltage supply
and the number of installed transceiver modules, up to two rectifier modules are inte-
grated per equipment rack.
