Signal Information
The DC input connector is located on the bottom, right side rear of the
BTS. The BTS is designed for –60 to –40 VDC.
The TME DC power connection is for outdoor configuration and only in
use if the Thermal Management Enclosure (TME) is used.
Motorola does not recommend the PDE be used to support
indoor configuration The PDE is not configurable for
indoor sites, and in general, it does not locate surge
protection functions appropriately for indoor cellsites.
For indoor, power and surge protection functions should be
implemented according to Standards and Guidelines for
Communication Sites using telecom–grade third party
equipment that is available through the ancillary group.
