Objective
This section contains general information for installing a Power
Distribution Enclosure (PDE) with Heat Exchanger (HX). See
Figure 4-22.
The optional PDE is a stand–alone unit external to the TME.
When in use, the PDE provides Primary surge for input power, customer
alarms, GPS, external antenna(s) and span lines; in addition to AC/DC
power conversion for the SC480 base unit and optional external PAs.
If battteries are used as backup, their cabling is routed to the PDE.
The present manual contains high level information on only one of two
manufacturer’s of the PDE.
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.
