2.2 Battery Compartment
When viewed from the front, the battery compartment is on the
left side of the battery box. This large compartment is pro-
tected by a padlockable door panel, and contains louvered and
screened side-wall vents for air circulation. On the inside walls
of the compartment are tie-down railings to secure the batter-
ies. Provided is a battery spacer block (shown in Figure 4)
which can be used to help insure a snug fit when smaller batter-
ies are used. The open top surface allows ample access to any
cable access holes in the cabinet installed above the battery
box.
2.2.1 Door Panel
The battery compartment is protected by a full-size removable
door panel which provides ample technician and equipment ac-
cess to the interior of the compartment. For security, at the top
of the panel are two cup-washer screws, which unlock with a 216
tool or can wrench. A padlock hasp offers additional security.
When closed and locked in position, a gasket on the inside pe-
rimeter of the door panel abuts or makes contact with the outer
perimeter of the compartment’s opening. When the hex cup-
washer screws (door lock) are tightened, the door panel and
gasket provide a seal to protect the batteries installed inside the
compartment.
2.2.2 Battery Tie-down Railings
On both the left and rear inside walls of the battery compart-
ment is a slotted, full-width, tie-down railing used to secure
batteries installed in the compartment. The provided tie-down
strap can be anchored to these railings then wrapped around
the batteries and tightened, to hold batteries in place.
2.2.3 Battery Spacer Block
The battery box is provided with a sturdy, rectangular, battery
spacer block that is designed to be used between the back wall
of the compartment and the rear of the installed batteries, to
help insure a snug and square fit of smaller batteries placed in
the compartment.

net (typically outdoors) and on top of a concrete pad. The
mounting surface as well as the hardware used all must be capa-
ble of supporting the weight of the both the battery box, the
cabinets mounted above the box, as well as the weight of any
equipment in the cabinets and the batteries mounted in the bat-
tery box. Run all cables to the mounting location, perform all
trenching, trench cable placements, and backfilling, and install
any concrete pads, prior to installing the battery box and mounting
the cabinets to the battery box.
3.3.2 Mount Boxer in a location with an adequate earth
ground and power access, with unobstructed cabinet access,
and which insures the best lighting, ventilation, heat dissipa-
tion, and equipment access. Verify sufficient space exists to
remove the door panels, to access and mount the cabinet, and
to adequately install, access, prepare, and dress all cables and
batteries. Adequate horizontal and vertical space should be be
left between any multiple installations to allow for cabinet
opening, panel removal, equipment access, and cable routings
and preparations. Follow company practice for the proper dis-
tance from the cable entry point or from upstream or
downstream equipment.

- KNOCK-OUT REMOVAL NOTE -
Always remove knock-outs (in the Boxer cabinet mounted
above the battery box) where holes are desired before mounting
the battery box or cabinet, regardless of the type of knock-out and
regardless of the order of the mounting steps. All knock-outs
should be knocked out from the inside of the cabinet, except for
the small 0.575" knock-outs (which should be knocked out from
the outside of the cabinet) or the concentric knock-outs.
3.5.2 Joining the Boxer Cabinets and the Battery Box
Regardless of the mounting type, attach the two Boxer cabinets
to the battery box prior to mounting or installing the conjoined
units. To join the units, follow the steps below:
1. Open and prepare all Boxer units. Open the door of both
Boxer cabinets and remove both access panels of the bat-
tery box, for easier handling and mounting hole access.
2. Locate and open parts/hardware kit. Find the bag of hard-
ware and parts located inside the battery box. Open the
bag and spread out the parts for easy access.
3. Remove knock-outs in the both Boxer cabinets. If not al-
ready done, remove any required knock-outs in the
equipment cabinet and the side car cabinet (see Paragraph
3.5.1 and the KNOCK-OUT NOTE at this time). Also, re-
move the small knock-outs in the right side wall of the
equipment cabinet (where the side car cabinet will attach
to it).
4. Set equipment cabinet on battery box. Lift the Boxer
equipment cabinet and place it on top of the battery box.
Slide the cabinet to align the five holes in the top surface
of the battery box with the matching holes in the bottom
of the equipment cabinet.
5. Attach equipment cabinet to battery box. After aligning all
holes, secure the units together using the included hard-
ware (insert, thread and tighten a bolt (plus a washer)
through each set of aligned holes. Secure bolts with nuts.
- LIFT-EAR NOTE -
The lift-ear on the right side of the 20-RU Boxer equipment
cabinet should be removed prior to mounting the side car
cabinet. Use the same lift-ear mounting hardware to fasten the
side car cabinet to the equiment cabinet, and re-install the
lift-ear between the cabinets prior to threading and tightening the
hardware.
6. Set side car cabinet on battery box. Lift the Boxer side car
cabinet and place it on top of the battery box. Slide the cab-
inet to align the four holes in the top surface of the battery
box with the matching holes in the bottom of the equip-
ment cabinet. Also align the holes in the back wall of the
side car with the holes in the right wall of the equipment
cabinet.
7. Simultaneously attach side car cabinet to equipment cabi-
net and battery box. After aligning all holes, secure the
units together using the included hardware (insert, thread
and tighten a bolt (plus a washer) through each set of
aligned holes. Alternate the bolt installation between the
bottom bolts and rear-wall bolts (so that the first bolt to be

installed is at the bottom of the side car cabinet, the second
bolt installed is in the rear wall of the side car cabinet, then
repeat this alternating patterning by installing another
bolt at the bottom, then another at the rear wall, until all
bolts are installed). Tighten all bolts and nuts.
3.5.3 Mounting Conjoined Units on a Concrete Pad
Follow the steps below to mount the conjoined Boxer cabinets
and battery box and on a concrete pad. Order and use the op-
tional A90-BXA-19PT2 Pad Mount Template Kit for mounting
on a concrete pad. Use the numbered steps below and the in-
structions in Figure 9 to mount the conjoined Boxer cabinets
and battery box on a concrete pad. These instructions are guide-
lines; you must design, dig, mix, pour, and install the concrete pad
per local building codes and practices. Note the following addi-
tional concerns for concrete pad installations:
SVerify all required floor, ceiling, and wall cabinet knock-
outs have been removed (see the KNOCK-OUT NOTE and
Paragraph 3.5.1), in all cabinets.
SSelect a mounting location that is dry, grade level or high-
er, and will support a 63" X 52" concrete pad (min). These
dimensions include 1 foot of concrete to extend out from
each side of the conjoined units.
SIf placing the concrete pad next to an adjacent structure,
Westell suggests a 24" distance between the cable access
door panel and any structure to allow for easy cable access.
Verify the cabinet doors can be fully opened.
- CONCRETE PAD MOUNT NOTE -
For concrete pad mounting, prepare and pour the concrete pad
(and install the accompanying conduit or ductwork) per local
codes and company practices, insert anchors in the wet concrete
precisely where holes at the bottom of the battery box are located
(holes are 0.344" in diameter), and allow the concrete to dry,
prior to mounting the Boxer units. Westell recommends using the
pad mount kit to facilitate precise anchor placement.
- CONCRETE PAD HEIGHT NOTE -
The pad location must be grade-level or above - it must not be be-
low grade-level. The location must be able to support the com-
bined weight of the conjoined Boxer cabinets/box and all internal
equipment, including batteries. Always follow local installation
codes, procedures, and practices.
Concrete Pad Mounting Steps
1. Determine exact concrete pad location. Select and prepare
the location for the concrete pad, per company practice
and local codes. When determining the size of the pad, al-
low for 12" of concrete to extend out from each side of the
battery box (so the overall pad length and width measure-
ments are 2 feet wider than the battery box).
2. Prepare template. Perform Steps 1-3 of Figure 9.
3. Prepare the pad for conduit or ductwork. Dig and frame
the pad location per company practice. Once the pad is
framed for concrete, but before pouring gravel or con-
crete, install any cable conduit or ductwork that is desired
to be routed through the concrete and which will enter the
battery box from the bottom.
4. Prepare the pad for concrete (add gravel). Fill and com-
pact the pad site with gravel, per company practice.
5. Prepare and join all Boxer units. If not already done, per-
form the steps in Paragraph 3.5.2 to open all Boxer units,
to locate the bag of hardware in the battery box, to remove
knock-outs, and to join the units.
6. Pour concrete, place the template, then set insulator gas-
ket and battery box on dry concrete. Perform Steps 4-7 of
Figure 9 to pour the concrete, to place the template (with
anchors attached) on the wet concrete, and once the con-
crete dries, to place the insulator gasket and conjoined
Boxer units on the dry cured concrete.
7. Test installation firmness. Test the installation by attempt-
ing to move the conjoined units. Correct any looseness.
8. Determine next step. Proceed to Paragraph 3.6, 3.7, or 3.8
to make ground connections, to install conduit, ductwork,
fittings, and or cables, and make battery connections.
- GROUNDING NOTE -
Always follow local safety precautions and standard operating
procedures for grounding the equipment when installing, up-
grading, repairing or maintaining equipment. Any instructions or
information contained herein is subordinate to local codes, oper-
ating procedures or practices.
3.6 Making Ground Connections
As the battery box is designed to be mounted with a Boxer
equipment cabinet and side car cabinet, ground lugs and post
are not provided in the battery box itself, but instead provided
in the cabinets mounted above it. However, earth ground pro-
visions and connections must be considered when installing the
conjoined units, and earth ground should be brought up
through the bottom of the battery box similar to all other cable-
type access (such as electrical and signaling). Copper ground
lugs that accommodate #6 to #14 gauge wire are provided on
a ground plate on the interior floor of the Boxer equipment
cabinet (see Figure 10). Also on the plate are eight sets of bond
posts. One set of posts should be populated with a ground strap
to the side car cabinet.
To ground the battery box to the equipment cabinet’s ground
plate, two bonds straps (provided) must be installed, as ex-
plained in the steps that follow.
1. Locate the bond straps. Find the bond straps that are pro-
vided in the kit shipped with the battery box. One bond
strap is to be installed inside the battery box, and one is
installed in the cabinet, at the bottom. Note that each ring
end of each strap has a hole in it, and also note that one
hole is larger than the other.
2. Install small end of the cabinet bond strap. Install the ring
end with the smaller hole around a post on the Boxer
equipment cabinet’s ground plate.

Install battery box.
Once the battery box holes are aligned with the matching holes in
the template, set the battery box on top of the insulating gasket
and template. When the
holes are aligned, insert a
bolt through each |
set of aligned holes,
and drive the bolts
into the threads of
the anchors in the
concrete under the
template. Tighten
all bolts securely,
and test the
installation
stability by
attempting to
move or wiggle
the box.
Tighten any
looseness.
Prepare concrete pad and place template on pad.
Dig and frame the pad location per company practice. Allow for 12"
of concrete past the perimeter walls of the template (a 48" wide by
42" deep pad is suggested). Once the pad is framed for concrete,
but before pouring gravel or concrete, install any cable conduit or
ductwork that is desired to be routed through the concrete and which
will enter the battery box from the bottom. Fill and compact the pad
site with gravel per company practice. Pour concrete and level to
grade or slightly above − the top surface of the pad must not be be-
low grade level. While the concrete is wet, set the template onto the
top surface of the concrete, being sure the anchors are fully im-
mersed and surrounded by wet concrete. Remove any spilled con-
crete from the top of the template or from the bolts before it dries.
After concrete dries, remove bolts. When the concrete is
cured, remove the bolts.
If the insulating gasket is used (shown in Step 1), place it on top of
the template, and be sure it does not cover
the holes in the template below it
where conduit, innerduct or
cable access holes are
desired.

box near the left wall. Attach the large end of the strap to
the bolt that enters the top left front corner of the battery
box from the cabinet above. This bolt also secures the
bond strap located inside the equipment cabinet above.
Secure the bond strap with the provided nuts.
5. Route earth ground wire to main Boxer cabinet ground
plate. Run an earth ground wire into the battery box up
through the cable compartment, through a knock-out in
the main cabinet above the battery box, and to the desired
ground lug in the ground plate of the equipment cabinet.
6. Seal the earth ground entrance hole. Depending on the
type of fitting or grommet used, it may be necessary to seal
the ground wire entrance hole, as stated in the note below.
- NOTE -
To improve the integrity of the cable entry seals when rubber
grommets are used, a water-proof foam or silicone sealant
should be used on the interior side of the cabinet, around the ex-
posed grommet and cable entry.

3.7 Making Cable Access Compartment Connec-
tions (Installing Fittings and Conduit)
3.7.1 When a battery box is attached to a Boxer cabinet
above it, extra lengths of cables and conduit are needed for the
additional height distance of the battery box, and an additional
AC fitting may be used at the bottom floor of the battery box.
Make these additional connections per company practice. At-
tach any grommets, conduit, innerducts, and/or fittings in the
appropriate knock-out holes in the upper cabinets.
3.7.2 Route and feed cables through the conduit and the
cable access compartment of the battery box, all per company
practice. Also gently feed/pull the communications cable(s), if
available at this time, from the outside up through the liquid-
tight tubing or steel conduit to the inside, allowing an adequate
amount of slack in the cable to secure to connectors at a later

installed, rubber grommets can be used to seal the communica-
tions cabling in the cabinet.
3.8 Making Battery Compartment Connections
To make battery connections in the battery compartment, a
battery heater pad (optional), batteries, and battery cable must
be installed. The paragraphs below provide a description of
these procedures.
3.8.1 Installing the Heater Pad (optional)
An optional battery heater pad can be ordered and used with
the battery box. If used, unroll the heater pad. Place the heater
pad into the bottom of the battery compartment (Figure 13),
connector cable side up, and connector end on the right side of
the tray. Spread out the pad to cover the compartment floor.
Connect the heater pad’s connector to the battery cable (Con-
nector C in Figure 12) in Paragraph 3.8.2 after the battery cable
is installed.
3.8.2 Installing the Battery Cable
A special battery cable (Figure 12) is shipped with the battery
box, to facilitate backup battery connections. The battery
compartment end of this cable contains 4 connectors (shown as
connectors A, B, C, D in Figure 12), which are connected to the
batteries and the battery heater pad in the battery compart-
ment. The power end of the cable also contains 4 connectors
(shown as connectors E, F, G, and H in Figure 12), which are
connected to AC and DC power connectors in the main cabinet
above the battery box. The middle of the cable contains a spe-
cial grommet (fitting with a threaded coupler and lock nut)
which is installed in the hole at the bottom of the Boxer main
cabinet. Follow the steps below to connect the battery cable.
1. Locate battery cable. Find the battery cable located inside
the kit of parts shipped with the battery box, and remove
it from its protective wrapping. Note the special water-
proof grommet and nut in the middle area of the cable.
2. Remove knock-out in main Boxer cabinet. If not already
removed, locate the main cabinet’s bottom knock-out that
is provided for the battery cable and remove the knock-
out.
3. Remove nut from battery cable’s middle grommet. Un-
screw and remove the lock nut from the threaded end of
the special grommet in the middle of the battery cable.
4. Route power end of cable into the the main Boxer cabinet.
Starting inside the battery box battery compartment,
route the Power or main cabinet end of the cable (with the
E, F, G, and H power connectors) up through the previous-
ly removed grommet lock nut installed in the knock-out
hole in the cabinet, and into the main boxer cabinet. Pull
the battery cable up as far as it will go, until the special
grommet in the middle of the cable abuts the hole edges
and the threaded part protrudes into the main cabinet.
5. Secure cable’s middle grommet in the knock-out hole.
Press and hold the cable’s special grommet against the
knock-out hole and screw the threaded lock nut back onto
the threaded part of the grommet. Fully tighten the nut.
6. Install optional battery heater pad. Install the optional
battery heater pad, if ordered or equipped. Place the pad
on the battery compartment floor, with the cable/connec-
tor end facing to the right (it should abut the divider wall
between compartments).
7. Connect heater pad to battery cable. Locate the connector
at the end of the heater pad cable and connect it to Con-
nector C of the battery cable.

nect it to the appropriate connector of the battery charger
(rectifier) in the cabinet.
3.8.3 Installing the Batteries
Before battery installation, first install the battery cable by per-
forming the steps in Paragraph 3.8.2, then install the optional
heater pad (see Figure 13), then install the batteries, per com-
pany practice or per the steps below. The total battery weight
cannot exceed 250 pounds. See Figure 13 and Table 1 for bat-
tery compartment dimensions.
1. Select batteries. Select the appropriate size and type of
batteries per company practice and per the equipment re-
quirements.
2. Install the optional battery spacer block. To h e l p i n s u r e a
snug battery fit, install the optional battery spacer block if
the batteries are small enough to accommodate the instal-
lation of all the batteries plus the spacer block. The left
wall tie-down railing can be used to adjust the installation
depth of this spacer block. Orient the block as shown in
Figure 13, and insert the left side flange of the block into
the left-wall tie-down railing, per the battery depth. Se-
cure the right side of the block to the holes located in the
compartment divider wall.
3. Verify the optional battery heater pad is installed. If using
the optional battery heater pad, install it per Step 6 in
Paragraph 3.8.2.
4. Place batteries in the battery compartment. Gently place
the batteries in the battery compartment, on top of the op-
tional installed heater pad. Press the batteries up against
the left and rear compartment walls (or the battery spacer
block). Do not place a battery on the heater pad cable or
connector, to avoid possible damage.
5. Jumper the batteries together. Jumper the batteries to-
gether, per company practice.
6. Connect battery cable connectors to batteries. In the bat-
tery compartment, locate Connectors A and B of the
battery cable (see Figure 12) and connect them to the
proper battery terminals, per company practice.
7. Make battery compartment temperature sensor connec-
tions. Locate the battery compartment’s temperature
sensor cable (install it if not pre-installed with the batter-
ies) and connect it to Connector D of the battery cable.
8. Connect DC leads to screw terminals of battery charger
(user provided). Locate the battery cable’s DC leads (G
and H in Figure 12) and connect them to the screw termi-
nals of the battery charger’s DC screw terminal strip, per
company practice. Connect the red positive lead to the +V
screw terminal, and connect the black negative lead to the
-V terminal.

3.10 Closing and Locking the Cabinets
Upon completion, the installer should close and lock the Boxer
cabinet and the battery box by replacing both compartment
door panels and tightening the cup-washer screws with a can
wrench or 216 tool. The battery box compartment panel op-
tionally can be locked with a padlock (customer supplied) via
a hole provided in the provided padlock flange. Pick up any
tools and materials at the installation site, and clean the site of
any trash or debris.
