Board IC-LU (ROF 157 5129)
Revision R2A and higher
Note: Use only the cable (TSR BS 902 0001/__ or equivalent) for the wiring to the MDF.
External power input: This cable is used if the current of all Base Stations connected to the IC-LU exceeds 1.5A.
This cable connects either to another power supply in another cabinet or to the same cabinet’s power supply. The
current fed by this cable must also be considered in the power calculation of the BML 351 048.
Overvoltage Protection
All lines leading outside the building to Base Stations must be fitted with 90V gas-filled surge arresters between
every wire to ground.
