Note: When closing and locking the door,the door must be pushed fully closed be­fore actuating the swing handle, or dam­age to the locking mechanism may result.

2.1.2.1 Large Cabinet Door

A full‐size locking door provides ample technician and equip­ment access to the interior of the cabinet and also helps protectthe cabinet from tampering and vandalism. When the cabinet ismounted and the door is open, the clearance or distance fromthe back of the cabinet to the outer edge of the open door isapproximately 43.2” (as shown in Figure 3). The cabinet's cool­ing system is a heat exchanger mounted to the door. At the insidebottom of the door is a wind‐latch, shown in Figure 2, which pro­tects the door (and technician) from possible wind damage. Thewind latch restricts the door's swing‐out angle to a safe but func­tional opening (105 degrees). In the closed position, the insideperimeter of the door abuts a gasket installed around the outerperimeter of the cabinet's door opening. When the door isclosed and tightened, the door and gasket provide a weather‐tight seal to protect all equipment installed inside the cabinet.The door sensor is described in Paragraph 2.2.2.

2.2.4 Cooling System / Heat Exchanger

2.2.4.1 The Boxer‐30 cabinet features an active heat‐ex­change system that compensates for the effects of internalequipment heat and external solar and temperature loading in­side the cabinet. At the core of the heat exchange system arenumerous aluminum fins on each “side” of a sealed divider wallwithin the heat exchanger. The dual air‐path exchanger usesone fan to blow cool outside air past the “exterior air side” finsof the heat exchanger and to direct the heated air out thescreened holes on the sides of the fan cover. Conversely, a

second fan circulates warm inside air down past the “interiorair side” fins of the heat exchanger and blows cooled air backthrough the main cabinet compartment.

2.2.4.2 The internal and external fans of the heat exchangerare thermostat controlled. The internal heat exchanger fan willturn on at 10% speed when the internal temperature reaches70�F (21.1�C) and will reach full speed when the internal tem­perature reaches 80�F (26.7�C). The external heat exchangerfan will turn on at 10% speed when the external temperaturereaches 90�F (32.2�C) and will reach full speed when the intern­al temperature reaches 100�F (37.7�C). Each fan will turn offwhen the temperature drops 5�F (3�C) below it on temperature.

2.2.5 AC Duplex & GFI Outlets for Installed Equipment

In the bottom‐right rear corner of the cabinet are two AC du­plex outlets (with a 1/2” fitting below one on the cabinetexterior surface), for powering any customer‐supplied AC‐powered equipment mounted in the cabinet. When an externalAC power source is connected to these outlets, AC power alsocan be provided to the GFI convenience outlet in the lower‐leftfront corner of the cabinet (to facilitate the installer's testequipment powering), by installing the provided AC 3‐wirecable.

2.2.6 Grounding and Bonding Center

3.5 Removing the Knock‐outs

Knock‐outs should be removed prior to mounting the cabinet.Do not remove knock‐outs if they will not be used. See Figure 9or Table 1 for knock‐out sizes, quantities, and locations, and fol­low the steps below to remove the knock‐outs.

1. Open the cabinet door. If knock‐outs will need to be re­moved, using a 216 tool or can wrench, open the large frontdoor of the Boxer‐30 cabinet to access the knock‐outs.

2. Remove knock‐out(s). Prior to mounting the cabinet, percompany practice, remove as many appropriately‐sizedknock‐outs at the bottom of the cabinet as needed for thespecific application (consider ground, power, and com­munication cable access needs, venting, and whetheroptionally mounting a battery box with the cabinet).

3. Install rubber grommets or conduit fittings. Install eithera heavy‐duty rubber grommet or the conduit fitting ofchoice (liquid‐tight recommended) in each selectedknock‐out hole. If an optional vent is desired, the providedvent cap can be installed in one of the smaller knock‐outs.

4. Close the cabinet door. Once the knock‐outs are removed,lock the door using the 216 tool or can wrench, to minimizepossible product damage and personal injury.

3.6 Mounting the Cabinet

The Boxer‐30 cabinet is typically mounted outdoors, aboveground, on a concrete pad. Top and bottom mounting bracketsfacilitate wall or H‐frame mounting. Concrete pad mounting istypically used in conjunction with the optional Boxer batterybox. An optional pad mount template kit is available for easyand convenient cement anchor placement. All mounting hard­ware (not provided) must be capable of supporting the weightof the Boxer‐30 cabinet plus the weight of any equipmentmounted in it. For convenience, lift hooks or ears are providedfor temporary lifting purposes (do not use lift ears from whichto hang the cabinet in permanent installations). Always use ap­propriate life equipment. Run all cables to the mountinglocation, perform any trenching, trench cable placements, andbackfilling prior to the cabinet mounting, and clear the installa­tion area of any debris, vegetation, and unneeded equipmentor obstacles.

‐ KNOCK‐OUT REMOVAL NOTE ‐

Always remove knock‐outs where holes are desired beforemounting cabinet or securing the battery box, regardless of theknock‐out type and regardless of the order of the mounting steps.All knock‐outs should be knocked out from the inside of thecabinet, except for the small 0.575” knock‐outs, which are to beknocked out from the outside of the cabinet.

3.6.1 Mounting on a Concrete Pad

The Boxer‐30 cabinet can be mounted on a concrete pad, typi­cally with an optional Boxer battery box (and “side car”). Whenmounting with a battery box, remove the five small knock‐outson the bottom of the Boxer‐30 cabinet which match holes in thetop surface of the battery box. To facilitate the concrete anchorbolt placement, order and use the optional A90‐BXA19‐PT1pad mount kit (listed in Table 2) for complete details on pad‐mounting the Boxer‐30 cabinet. The mounting surface and hard­ware used must be able to support the combined weight of the cabinetand the equipment mounted inside the cabinet. Always use appro­priate lift equipment.

3.6.2 Mounting on an H‐Frame

To mount the Boxer‐30 on an H‐frame, follow company prac­tice or the steps below. See Figure 14 for an H‐frame mountingillustration. The approved mounting surface, framework and hard­

ware used must be able to support the combined weight of the cabinet

and the equipment mounted inside the cabinet. Use appropriate lift

equipment.

1. Determine exact mounting location in H‐frame. Select andmark the exact horizontal and vertical final mounting loca­tion within the H‐frame. The spacing between the top andbottom horizontal‐rail mounting holes should be 62.6”(on centers). Westell recommends leaving a comfortableinstaller working height, leave adequate space under Box­er‐30 for cable access, as well as in front of the cabinet toallow the door to open, and at the sides in the event of anymultiple installations.

2. Remove knock‐outs. If not removed already, see the stepsin Paragraph 3.5 (Removing the Knock‐outs) to remove theknock‐outs where any cable access holes (or holes formounting the optional battery box) are desired.

3.6.3 Wall Mounting

Follow company practices or the steps below to mount the Box­er‐30 cabinet to a wall. The approved mounting surface,

framework and hardware used must be able to support the combined

weight of the cabinet and the equipment mounted inside the cabinet.

Use appropriate lift equipment.

1. Find best wall position. Locate the best mounting positionfor the cabinet on the wall. Verify this location meets allcabinet spacing requirements and company practices.

2. Remove knock‐outs. If not already removed, see the stepsin Paragraph 3.5 (Removing the Knock‐outs) to remove theknock‐outs where any cable access holes (or holes formounting the optional battery box) are desired. Note thatif a Boxer “Side Car” cabinet is being installed with theBoxer‐30, remove the small knock‐outs on the Boxer‐30'sright side wall to accommodate the side car's mountingbolts and any cable knock‐outs.

3. Locate the mounting hardware. Bring the appropriatewall‐mounting hardware to the installation site. The hard­ware must be able to support the weight of the cabinet plusthe weight of the added internal equipment. Use a mini­mum of 10 mounting fasteners (such as lag bolts).

4. Determine mounting height and mark top hole locations.Measure and mark the top mounting hole locations on thewall, in a straight level line. This can be done by lifting andleveling the cabinet then marking the mounting hole loca­tions, or by measuring (without lifting the equipment as atemplate). Two of the mounting bracket holes are 16”apart on centers, to facilitate mounting on standard wallswith studs 16” apart on centers. The vertical distance be­

tween the holes in the installed top and bottom mountingbrackets (when attached to the cabinet) is 62.6”. Westellrecommends using 5 mounting bolts in each mountingbracket. In addition to allowing for a comfortable installerworking height, leave adequate space under Boxer‐30 forcable access, as stated in Paragraph 3.3, as well as in frontof the mounting to allow the door to open and at the sidesin the event of any multiple installations. With a markingutensil, mark the top mounting holes to be drilled, in a lev­el horizontal line, at the desired wall height.

5. Drill top mounting holes. Drill appropriately‐sized pilotholes, slightly smaller than the width and depth of themounting bolts, screws or fasteners, at the marked loca­tions. Do not drill the holes too large.

6. Partially install bolts. Partially install the bolts until only1/2” remains.

7. Lift cabinet, and align mounting holes. Using appropriatelift equipment, lift the cabinet to the protruding bolts,align the top mounting bracket's keyholes with the bolts,then hang the cabinet from the bolts. If using lift equip­ment, use two cables or straps of equal length, oneconnected to each lift ear, for a balanced symmetrical lift.The lift ears are provided at the top of the cabinet, one ateach side wall, and each lift ear has a 2” hole in it. Neverrelease the cabinet from the lift equipment until the in­stallation is complete and determined to be safe.

8. Fully install the top mounting bolts. Verify the cabinet islevel. Finish driving the top mounting bolts until they aresnug and the cabinet is flush and tight against the wall.Manually test the bolt tightness to verify the bolts will sup­port the cabinet weight before the next step. Correct anylevel or mounting bolt discrepancies.
