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‐16 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‐most three
are typically for customer cable access, and the rear‐most knock‐
outs are typically for Network cable access. The knock‐out sizes
and quantities are shown in Table 1 and Figure 9. A “concentric”
knock‐out is provided for both Customer and Network access:
depending upon which direction the knock‐out is removed, ei
ther a 1/2” or 3/4” hole will be produced. Do not remove a
knock‐out unless it is absolutely necessary to do so for cable in
gress 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‐16 cabinet where an option
al 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.

AC Conduit Fitting
A ½” AC conduit fitting is provided on the exterior bottom sur
face of the cabinet (see Figure 8) through a knock‐out hole near
the back right corner, to facilitate conduit attachment. Inside the
cabinet, the fitting is connected to an AC outlet box immediately
above it inside the cabinet.
