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 be
low 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 ones
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 6. Do
not remove a knock‐out unless it is absolutely necessary to do
so for cable ingress and egress, and use either tight‐fitting rub
ber 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 com
pany‐approved tools to remove knock‐outs.
Battery Box 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).
