DC cable requirements for 60 W RF Modules
48 VDC power can be fed to the RF Module directly from the System Module or from an
external power source. In both cases, the internal power cable with boot included in the
RF Module delivery must be connected to the RF Module to provide IP65 protection.
If the cable path between the System module and RF Module is less than 2 m then
•
the internal power cable included in the RF Module delivery is connected directly to
the System module and RF Module. The optional 4 m (13.1 ft) power cable FPTA
472246A can also be used between the System Module and RF Module.
If the cable path between the System Module and RF Module exceeds 4 m (13.1 ft),
•
then a pair of FSEC/FSESs (Flexi System External OVP) must be installed between
the System module and RF Module. For details, see Creating Flexi Multiradio BTS
Site Configurations in respective system documentation.
For all RF Modules with or only modules with the 3-terminal DC connector if 48 VDC
•
power is supplied to the RF module from an external power source, then an
FSEC/FSES must be installed between the external power source and the RF
module. The internal power cable included in the RF module delivery must be
connected from the RF module to the FSEC/FSES.
DC cable requirements for 80 W RF Modules
The DC cable is not included in the 80 W RF Module delivery. 48 VDC power can be fed
from a System Module or directly from an external power source.
If the cable path between the System Module and RF Module exceeds 10 m (32.8 ft),
then a FSEC/FSES (Flexi System External OVP) must be installed next to the System
module or external power source. For details, see Creating Flexi Multiradio BTS Site
Configurations in respective system documentation.
OVP DC ampacity must not be lower than PDU fuse rating.
If 80W RF Module is used with FSMC/D/E (FPFB 30A PDU), FSMF (FPFD
A.103 30A PDU), or FPFC A.102 30A PDU then the rules in
Table 10: DC Cable Requirements for 80 W RF Modules apply.
For newer FPFD PDU version A.204 or FPFC A.203 with 43A label a single DC
cable is sufficient and dual DC cable must not be used. Conductor wire
diameter of DC cable need to be selected based on the PDU fuse rating.
With ESMB or ESMC single cable is sufficient for all 80W RFM modules as 36A PDU is
used.
