ened and tightened with a can wrench or 216 tool, and the
pin‐in‐hex screws are loosened and tightened with a pin‐in‐hex
wrench (wrench provided with the ‐NHE3G). In addition to pro
viding security, when fully‐tightened, these screws help to seal
the cabinet and protect the interior environment from outside
elements or contaminants by compressing the door/panel's seal
ing gasket(s). Additional security is offered for the door via holes
in the door flanges which accept a field‐provided lock or pad
lock.
2.1.2.3
Mounting Brackets
Full‐width molded mounting brackets are provided at the back
wall of the Boxer cabinet, one at the top and one at the bottom.
Each bracket has nine mounting holes (top bracket) or slots
(bottom bracket). Use mounting fasteners with a diameter of up
to
3
/
8
”. The horizontal distance between holes is shown in
Figure 27. The vertical distance between the top and bottom
mounting bracket holes is 25.2”.
2.1.2.4
Side Lift Ears
The Boxer cabinet is equipped with two external lift ears or
brackets, one on each side, attached at the top of the cabinet.
These lift ears can be used to lift the cabinet using lift equip
ment, for mounting purposes. Each ear has a hole with a 2”
diameter, to accommodate various cable, strap, or hook sizes.
Always use two straps of equal lengths, one for each lift ear,
when using this method to lift the cabinet.
Do not use the lift ears
for permanent mounting.
2.1.2.5
Rear‐Access Panel (Detachable)
A 10.5” x 19.5” rear‐access panel, shown in Figure 4, is located
at the rear of Boxer. The purpose of the access panel is to facili
tate equipment access, cabling, and servicing. A gasket on the
rear of the cabinet at the panel opening seals the panel open
ing. The rear‐access panel is secured with six cup‐washer
screws (on the ‐NHE3) or with six pin‐in‐hex screws (on the
‐NHE3G) and can be removed with a 216 tool or can wrench
(for the ‐NHE3) or a pin‐in hex wrench (provided with the
‐NHE3G).
2.1.2.6
AC Conduit Fitting
A 1/2” AC conduit fitting is provided on the exterior bottom
surface of the cabinet through a knock‐out hole near the back
right corner, to facilitate conduit attachment or power cable ac
cess. Inside the cabinet, the fitting is connected to an AC outlet
box immediately above it.
2.1.2.7
Bottom Floor Knock‐outs
Multiple knock‐outs are provided on the floor of the cabinet. One
near the center rear of the floor is for cable ingress and egress for
an optional battery cabinet that can be mounted below the Boxer
cabinet (or for Network cables). Provided on the right side of the
cabinet floor are multiple intact knock‐outs, for easy Network and
Customer cable access. The front three are typically for customer
cable access, and the rear‐most knock‐outs are typically for Net
work cable access. The knock‐out sizes and quantities are shown
Figure 4.

in Table 1 and Figure 5. A “concentric” knock‐out is provided for
both Customer and Network access: depending upon which direc
tion the knock‐out is removed, either a 1/2” or 3/4” hole will be
produced. Do not remove a knock‐out unless it is absolutely nec
essary to do so for cable ingress and egress, and use either
tight‐fitting rubber grommets or liquid‐tight fittings, or other
proper and approved knock‐out hole sealants, to assure the best
internal air quality and weather‐resistance. Always use proper
and company‐approved tools to remove knock‐outs. There are
five, small, 0.575” diameter knock‐outs in the floor of the Boxer
cabinet where an optional battery box attaches to the cabinet
(hole patterns of both units match).
‐ KNOCK‐OUT REMOVAL NOTE ‐
Always remove knock‐outs where holes are desired before
mounting the cabinet or the optional battery box, regardless of
the type of knock‐out and the order of the mounting steps.
