Page 24: Opening The Enclosure
Installation 150-712-200-02 PENING THE NCLOSURE When handling the HRE-712 enclosure, always assume it is pressurized. Failure to relieve the pressure before removing its cover may result in serious personal injury. Exercise care when removing and handling the stainless steel dome. A damaged stainless steel dome may not seal properly. -
Page 25: Closing The Enclosure
150-712-200-02 Installation LOSING THE NCLOSURE To close the HRE-712 enclosure, perform these steps: Inspect the enclosure cover and baseplate for dirt, moisture, or mechanical damage, especially around the baseplate flange and O-ring. Remove any accumulation of dirt or moisture from the cover and replace any damaged components. -
Page 26: Pivoting The Hre-712 List 1
Installation 150-712-200-02 HRE-712 L IVOTING THE The HRE-712 List 1 mounting plate allows the unit to be tilted 31° from its vertical position. This reduces the headroom required in manhole installations from 10 inches to less than 3 inches and the amount of valuable air space required for such underground applications. -
Page 27: Appendix A - Technical Reference
150-712-200-02 Appendix A - Technical Reference A - T PPENDIX ECHNICAL EFERENCE Appendix A contains additional technical information about the HRE-712 List 1 and List 2 enclosures. The card cage inside each enclosure, shown in Figure 7, has 12 mounting positions for doublers and repeaters. They are front loading, arranged in three rows of four slots each. -
Page 28: Lightning Protection Unit
The gas tube parameters are equivalent to a TII 47 BT. The DC breakdown ranges from 300 to 500 volts. The tube can withstand at least 400, 10/1000, 500 amp discharges. Although the individual gas tubes are field replaceable components, ADC recommends replacing the entire LPU when any of its protector tubes are suspected of functioning improperly. See “Appendix B - Specifications”... -
Page 29: Cable Stub And Pressurization

Page 34: General Deployment Rules
Appendix A - Technical Reference 150-712-200-02 ENERAL EPLOYMENT ULES The HRE-712 is an airtight enclosure. The ambient environment traps heat generated by the installed cards and causes a significant rise in temperature within the enclosure. The number of doublers or repeaters that can be reliably housed in the HRE-712 is a function of each plug type, doubler version and solar exposure. - Page 35 150-712-200-02 Appendix A - Technical Reference The physical locations of the HRE-712 doubler enclosures are determined by three deployment rules: The first and most important deployment rule is to place the enclosures at the electrical limits of 35 dB of each span.
