HRE-500 List 1 July 25, 2002 5
HRE-500 Stub
The HRE has a 14 AWG, stranded ground wire and a four-pair, 20-foot
gel-filled stub for access to the doubler’s four ports. This 24 AWG stub has
foam skin insulation and a filled jacket. Each conductor has a dual insulation
consisting of an inner coating of natural, insulating-grade, high-density
cellular polyethylene covered by an outer skin of color-coded, high-density
solid polyethylene. Standard color codes allow for pair identification with
color compounds chosen for electrical balance and permanency. The
assembly is flooded with an Electro Thermo Plastic Rubber (ETPR)
compound, filling the air space between conductors.
A non-hygroscopic core wrap protects the core and provides improved
mechanical and electrical characteristics. The inner surface of the core wrap
is coated with the ETPR filling compound. The outer surface is coated with
an amorphous polypropylene compound. The cable core shield is a
corrugated copolymer-coated 8 mil aluminum tape. The outer jacket consists
of a black, low-density polyethylene material providing a flexible protective
covering that withstands exposure to sunlight, atmospheric temperatures,
ground chemicals and stresses expected in standard installations. The cable
complies with the requirements of ANSI/ICEA S-84-608-1994 and has an
outside diameter of 0.38 inches (10 mm).
The stub’s four pairs terminate on an internal assembly that contains the
card-edge connector and gas tube protector board. The stub pairs are routed
through a ferrite coil, which prevents EMI energy from exiting the stub pairs.
Figure 3 shows the identity of the four ports for each cable stub to provide
access. The CO ports connect to the upstream cable pair connections of either
another doubler or the line unit. The field ports connect to the downstream
cable pair connections of either another doubler or remote unit.

Ground Wire
The ground wire is required for both EMI and voltage surge protection for the
installed doubler.
End Cap
There are five compression bolts on the end cap which work to create a
waterproof barrier. When properly torqued, these bolts compress the
neoprene washer (shown in Figure 4) that sits between the enclosure’s two
end plates. The washer expands against the sides of the enclosure to form a
waterproof barrier. This allows the enclosure to be installed anywhere in the
network, including underground locations where it may be submerged in
water.

Card-edge Connector
See Figure 3 on page 5 for the wiring diagram specifications.
Gas-tube Protectors
The four replaceable gas-tube protectors are equivalent to a TII 47BT and
have a breakdown voltage ranging from 300 V to 500 V. The breakdown
voltage is a function of voltage rise-time. The tubes can withstand at least
400, 10/1000, 500 Amp discharges.
Thermal Deployment Limits
HRE-500 and its doubler can be deployed in an ambient temperature up to
135 °F (57 °C) with full solar load and 145 °F (63 °C) without solar load.
A replacement kit containing 20, TII 47BT, gas-tube
protectors is available from ADC (part #132-1028-01). See
“Appendix B - Product Support” on page 16 for ordering
information.

INSTALLING DOUBLERS
To install a doubler in the HRE-500:
1Remove the small retaining screw from the lower front side of the case
(see Figure 2 on page 4).
2Loosen, but do not remove, the five compression bolts from the end cap
(see Figure 2), then remove the end cap.
3Insert the doubler or repeater into the end cap’s connector.
4Replace the case, then insert the retaining screw.
5Torque the five compression bolts in the proper sequence shown in
Figure 6 and Table 3 on page 12).
Figure 6. End Cap Compression Bolts
The five compression bolts must be torqued according to their
specified torque levels and in the numerical sequence shown in
Table 3 on page 12.

Installation 150-500-100-05

Always follow the torquing sequence in Table 3. Exact
torquing pressure is only required for installation in which the
HRE-500 may be submerged in water. Approximate torquing
is sufficient in all other installations.

MOUNTING THE ENCLOSURE
To mount the enclosure:
1Select a location for mounting the HRE-500 that allows access to wiring
and grounding connections through the cable fittings on the bottom of the
HRE-500.
2Place the HRE-500 in the chosen mounting location, then mark the
mounting hole locations. Figure 7 shows the mounting hole locations on
the enclosure.
Figure 7. Mounting Hole Locations (Front View)

Installation 150-500-100-05
14 July 25, 2002 HRE-500 List 1
3Do one of the following:
•If the installation location is wood, use a drill with a wood or metal
drill bit to drill mounting screw holes into the surface.
•If the installation location is concrete, use a drill with a concrete drill
bit that is slightly smaller than the diameter of the anchor nuts to drill
the mounting screw holes into the concrete surface.
4Insert the anchor nuts into the pilot holes and tap the anchor nuts into
place with a hammer.
5Use a 1/4inch slotted screwdriver to fasten the enclosure onto the
mounting location using the two screws and two washers provided in the
installation kit.
GROUNDING
The stub shield is not connected to the enclosure ground. When the stub is
spliced with the main cable the stub shield should be connected to the field
cable shield. Failure to do so will expose the signal pairs to stray EMI which
could introduce service affecting noise into the information payload. The
green ground wire must also be properly grounded to provide both EMI and
voltage surge protection to the doubler.
