Overview 150-458-100-05 UNCTIONAL ESCRIPTION The following section discusses the function of each component on the HRE-458. The enclosure consists of an aluminum card cage with a holding capacity for up to ten doubler units, a stainless steel composite baseplate, and a stainless steel cover that maintains weathertight integrity and provides efficient heat exchange to expel the heat generated within the units.
150-458-100-05 Overview Air-filled Stub Unit The air-filled cable stub on the List 2 unit (Figure 2 on page 4) is equivalent to an ALP FTS-PIC air core telephone cable (refer to Table 5 on page 27 for a complete description of the cable stub). The air-filled unit is intended for buried, aerial, and duct applications.
Overview 150-458-100-05 Figure 2. HRE-458 Air-filled Remote Enclosure An optional breather vent valve is enclosed in the List 2 shipping kit. This assembly is used to replace the pressure relief valve if the List 2 is not locally pressurized. The assembly allows the enclosure to breathe and keeps the internal atmosphere free of harmful contaminants.
