Objective
This section contains general information for installing a Thermal
Management Enclosure (TME). These procedures are utilized if the
BTS site is configured for outdoor use.
The purpose of the TME (Figure 4-15) is to protect the BTS from the
weather. The Compact BTS is installed in the TME and some cables are
connected to interior TME connectors, while others are routed out
through access holes. Figure 4-17 shows the Wall Mounting Bracket and
Pole Mounting Bracket Assembly.
The TME can be pole or wall mounted. The Heat Management System
(HMS) is attached to the TME and is used to regulate temperature within
the TME.
The TME is replaced as a whole should damage to the exterior no longer
allow protection from the environment or if damage should occur to the
TME connectors .

power source by the PDE or from battery backup routed through the
PDE. Power required is –48VDC nominal, range is –60 to –40 VDC.
