Page 12: Functional Description
Overview 150-504-100-03 UNCTIONAL ESCRIPTION The following section discusses the function of each component on the HRE-504. The enclosure consists of an aluminum card cage with a holding capacity for up to four doubler units, a stainless steel composite baseplate, and a stainless steel cover that maintains weathertight integrity. -
Page 13: Air-Filled Stub Unit
The common pressure supplied through the cable is approximately 9 PSI. This is sufficient to prevent water from entering the cable or housing. ADC recommends pressurizing the enclosure to a maximum of 12 PSI. HRE-504 List 1, List 1B, and List 2... - Page 14 Overview 150-504-100-03 To avoid pressure buildup, the pressure relief valve is set to release air at a maximum pressure of 15 PSI. Due to manufacturing tolerances of the springs, this maximum pressure has a tolerance of ± 3 PSI. This pressure and tolerance are well within the safety concerns that may apply to the housing, personnel, or cable.

Page 38: General Deployment Rules
Appendix A - Technical Reference 150-504-100-03 ENERAL EPLOYMENT ULES The HRE-504 is an airtight enclosure. The breather valve on the gel-filled units and the pressure relief valve on the air-filled units allow minimum ventilation to the atmosphere. This environment traps the heat generated by the installed plugs and, in effect, causes the heat temperature to significantly rise within the enclosure. - Page 39 150-504-100-03 Appendix A - Technical Reference The physical location of the HRE-504 doubler enclosures is driven by one of three deployment rules: The first and most important rule is to place each enclosure span to the electrical limits of 35 dB. This places the first doubler at the 35 dB location, the second at 70 dB, and the third at 105 dB.
