Page 12: Doubler Applications
The following section discusses the function of each component on the HRE-454. The HRE-454 consists of a metal alloy card cage with space for up to four remote or doubler units, a stainless steel composite baseplate, and a stainless steel cover which maintains weather-tight integrity.

Schrader air stem valve, and a pressure relief valve. The air cutoff valve is used to shut off the inlet air supply that is pumped from the main feeder cable through the 30-foot (9.144 M) stub into the HRE-454 enclosure. The cable stub is intended for buried, aerial, and duct applications.
Page 14: Pressurized Applications
PPLICATIONS For pressurized applications on the HRE-454, the Schrader air stem valve is used. A pressure gauge is attached to the valve for the purpose of measuring the internal pressure of the enclosure. This valve is also used to relieve the internal pressure prior to opening and removing the dome cover.

Page 17: Mounting
150-454-111-06 Installation OUNTING The HRE-454 may be mounted on a pole, a pedestal, a flat surface, or in a rack (Figure 5). Various methods for mounting the HRE-454 are detailed in the following sections. The mounting details for the various methods are as follows: Table 2.
Page 18: Large Pole Or Pedestal Mounting
Have the following equipment ready before you begin: • Four -inch (0.952 cm) lug bolts, 4 inches (10.16 cm) long (minimum) • Four -inch (0.952 cm) washers • One wrench • One pencil • One drill with a -inch (0.635 cm) bit February 25, 2000 HRE-454...
Page 19: Flat Surface Mounting
The desiccant bags shipped with the List 2A, List 2B, List 4, and List 6 units must be activated prior to closing the lid. Do this by removing the bags from their plastic container and placing them inside the enclosure. While mounting the enclosure, hold it securely to prevent personal injury or damage.

-inch nonmetallic washers. Nonmetallic washers are required to avoid a ground loop that may result if both the rack and the enclosure are grounded. ADC does not recommend using the rack ground for the enclosure ground since its integrity is not one-hundred percent reliable.
Page 21: Grounding
“Grounding a Pole Mounted Enclosure” on page 13 or use existing local Ω grounding practices to ground the enclosure. The HRE-454 requires a resistance of 25 or less to ground as measured with a megger-type Ohmmeter. The 8 MIL aluminum shield on the stub is connected to the card cage mounting brackets by a...

9). The test card provides access to all assigned cable pairs of the HRE-454. The card is used to test cable pairs and to check Central Office (CO) and field circuits by performing loopback, loop-through, short, and open testing of all cable pairs. A four-position slide switch on the test card enables technicians to select the type of test to perform.

Page 30 However, this limited extension is such that the HTC-400 could be inserted into the HRE-454 outdoor enclosure with the card cage retaining/locking bar in place. This allows the HTC-400 to be permanently installed in any slot where it provides loop-through of the cable pairs. This allows end-to-end metallic cut-through access to Sides 1 and 2 cable pairs without the need to rewire the shelf slots.

Page 37: Spare Connections
Spare Connections Each HRE-454 stub (with the exception of the List 3 and List 4 models) has 11 spare pairs. The HRE-454 List 3 and List 4 models provide access only to four spare pairs. On the List 3 and List 4 units, the 28 pairs have been grouped into seven, 4-pair groups.

Page 39: Hre-454 Deployment Rules For Hlu-431/ 432 Applications Vs. Type Of Doubler Used
Appendix B - Technical Reference Table 6 lists the deployment rules for the HRE-454 List 5 and List 6 enclosures for HLU-431 and HLU-432 applications. These rules are shown as a function of the type of doubler that is used in HLU-431 circuits. The HDU-409 mini-doubler requires less power and thus reduces the heat dissipated by the HLU-431 when the doublers (listed in column four) are used.
Page 40: Hre-454 Vertical And Horizontal Mounting Orientation
Figure 14. HRE-454 Vertical And Horizontal Mounting Orientation Deployment considerations determine the physical location of the HRE-454 doubler enclosures, which are: The first and most important rule is to place each enclosure span to the electrical limits of 35 dB. This will place the first doubler at the 35 dB location and the second at 70 dB.

Table 12 on page 51 shows how the two spare red and white pairs in both groups are used in the HRE-454 List 5 and List 6 enclosures to power the four slots for HLU-431 List 1B applications. The four spare pairs used to access the HLU-431 system relay alarm controls are also shown.
Page 43: Pinout Information
Pinout Information To use a specific shelf slot on the HRE-454, a remote, line, or doubler unit must be inserted. Insert the units into the desired shelf slot by lining up the gold fingers on each unit with the slot connector. Active pins are highlighted in black.
