1. The Eight-card Shelf
The Eight-card Shelf, model 751109/13, is used indoors to accommodate eight
service cards. The shelf is molded from specially treated polyurethane, making it
a lightweight, flame retardant product of high dielectric strength. Its polyurethane
body limits the possibility of many kinds of infiltration while providing reliable
isolation from external ground potentials.
The shelf is equipped with the connectors required for any of the plug-in cards
from the Teleline line of products. In addition, the shelf has a separate area to
accommodate a Power Supply Card, model 751313 (120 V ac/130 V dc),
751324 (24 V dc), or model 751316 (-48 V dc), and a Battery Backup Card,
model 751312 to provide an uninterruptible power supply (UPS). If the Battery
Backup is not used, then two Power Supply Cards may be installed for
redundancy.
The shelf is shipped with a station cable stub for connection to communications
equipment, a Polyolefin Insulated Cable (PIC) stub for connection to the Central
Office (CO) incoming cable, and a power cable.
The shelf’s features include the following:
• The station and CO cables connect to the shelf via individual printed circuit
boards.
• Each of the five card slots can accommodate two Tip and Ring pairs for
four-wire AC data applications, four-wire T1 applications, HDSL and ADSL
applications.
• The station and CO cables are prewired to male connectors for insertion into
the female receptacles mounted on the printed circuit boards inside the shelf.
The power cable provided is used to supply 120 V ac to the shelf when an
internal Power Supply Card is used. The cable may also be used for V dc
applications if the three-prong plug is removed.
• The shelf has been successfully tested for the UL standard (94V0) for flame
retardance.
• The unit is lightweight and easy to install. The weight of the shelf with the
motherboards is 22 lbs (9.95 kg).
• The enclosure resists the infiltration of dust, mist, and water from sprinklers.
For a view of the Eight-card Shelf, refer to Figure 1.

4. Shelf Mounting
The Eight-card Shelf should be installed as closely as possible to the point of
entry of the CO cable. Power will need to be routed to the shelf (24 V, -48 V,
130 V dc or 120 V ac). A Non-Fragmenting Lightning Arrestor Unit (model
751123 or 751126) is also highly recommended.
Caution
• Stand on a thick rubber mat and wear rubber gloves during the
installation procedure. It is preferable to perform these procedures on a
clear dry day when a Ground Potential Rise (GPR) or transients are less
likely to occur.
• It is strictly forbidden to install any additional hardware inside the shelf
or to drill any holes in its surface. Doing so would greatly compromise
safety and isolation.
1. Verify that you have the following customer provided tools and hardware
which are required to install the unit:
• Center punch
• Electric drill with a 5/32” diameter bit
• 7/16” hex wrench
• 1/8” common blade screw driver
• 1” x 4’ x 8’ plywood sheet and appropriate mounting hardware
• Cable clamps, tie wraps, and mounting hardware for routing cables exterior
to the shelf (quantity determined by the cable lengths involved).
2. Unpack the Eight-card Shelf and its installation hardware from its
protective box.

4. To mount the shelf, install the plywood backboard on the wall to provide
the installation with additional isolation from station ground. Then attach
the drilling template to the plywood surface where the shelf will be located.
As indicated on the template, drill three holes for the #14 screws supplied.
Remove the template and install the screws.
5. Before mounting the shelf on the wall, open the cover of the shelf by
removing the two wing nuts on the face cover of the shelf.
6. With the cover open, mount the shelf using the keyholes as per the
instructions given on the drilling template, and then tighten the #14 screws.
It is unnecessary to further isolate the screws from station ground.

5. Cable Connections
Caution
The CO cable should be kept at least 6” apart from the station cable and the
ground wire in order to prevent an electric arc between the two in the event
of damage to, or degradation of, their insulation. For an illustration, refer to
Figure 2.

5.1 Station Side Cable Connection
1. Feed the free end of the cable through the upper hole on the upper
right-hand side of the shelf, from the inside to the outside.
2. Slide the free end of the station cable through the nut of one of the 1/2”
strain reliefs provided.
3. Plug the male connectors into female receptacles TB1 and TB2. For a
diagram of the Station side terminal blocks, refer to Figure 3.
4. Take the remainder of the strain relief (gland nut, chuck, neoprene bushing,
and body and slide it up the cable from the free end outside the shelf to the
shelf opening. Secure the cable by holding the nut inside the shelf and
tightening the grip by turning the gland nut.
Danger
The cable wires should be tightly bundled together inside the shelf to
minimize the chance of a broken wire touching an adjacent plug-in card, or
from sagging into the isolation gap between the Station and CO side
motherboards.
5. Connections between the station cable and the site equipment cables can
now be made according to the color coding as appropriate.
For a listing of the standard color codes, refer to Table 2.
For a view of Station side motherboard interconnections, refer to Figure 4.

5.2 CO Side PIC Connection
If you wish to connect the incoming CO cable directly to the shelf without using
the PIC stub, refer to Section 5.3 on page 1-18.
To connect the CO side cable using the PIC stub
1. Slide the nut of the 3/4” strain relief supplied up the cable from the free end
of the stub.
2. From the inside of the shelf, pass the free end of the cable through the
bottom left-hand side.
3. Plug the male connectors into female receptacles TB1 and TB2, mounted in
the bottom left-hand corner of the shelf. For a diagram of the CO side
terminal blocks, refer to Figure 5.
4. Take the remainder of the strain relief (the gland nut, chuck, neoprene
bushing, and body), and slide it onto the cable from the free end, outside the
shelf, to the shelf opening. Secure the cable by holding the nut inside the
shelf and tightening the grip by turning the gland nut.

Eight-card Shelf 15
751109/13
5. Connections between the PIC stub and the incoming CO cable can now be
made according to the color coding of the station cable.
For a listing of the standard color codes, refer to Table 2.
For a view of CO side motherboard interconnections, refer to Figure 6.
The PIC stub must be spliced to the incoming CO cable using a
high-dielectric splice case. All interconnections should be completely
isolated from anything that is, or could eventually become, referenced to
station ground.
Danger
The sheath of the CO cable must not be connected to station ground. The
wires themselves should be tightly bundled together to minimize the chance
of a wire extending into the isolation gap.
