DC cable requirements for 6TX 40W RF Modules
The DC cable is not included in the 6TX 40 W RF Module delivery.
If the cable path between the System Module/external power source 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.
48 VDC power can be fed from an external power source.
If 6 TX 40W RF Modules are 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 11: DC cable requirements for 6TX 40W FRMC, FRPA, FRPB Modules
and Table 12: DC cable requirements for 6TX 40W FRHC, FRHF 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 PDU fuse rating.

Total configured output power is the total power for all three branches. For example, a 2+2+2 @ 40 W is
equal to 240 W.

The following power cables are available: FPCA 472806A (Dual, 2 m, 6.6 ft), FPCB 472817A (Single, 2 m,
6.6 ft), FPCC 472823A (Single, 2 m, 6.6 ft), FPTA 472246A (Single, 4 m, 13.1 ft). The dual power cable
requires two available PWR outputs on the System Module or PDU (excluding PWR AUX). It is
recommended to use the next available connectors in sequence. The FPCC and FPTA require removing
the connector from one end. Consider future expansion when choosing single or dual power cables.
