2.1.2.2
Door Handle, Door Locks and Panel Lock(s)
Built into the 2‐point latching door handle is a padlock hasp and
a tamper‐proof lock. The lock (Figure 4) is loosened and tight
ened with a can wrench or 216 tool (for the ‐7HE model) or a
pin‐in‐hex wrench (for the ‐7HEG model, wrench provided). In
addition to providing security, when fully‐tightened, this lock
helps to seal the cabinet and protect the interior environment
from outside elements or contaminants by compressing the door
and panel against their gasket(s). Additional security is offered
for the door via a hasp in the handle that accepts a field‐provided
lock or padlock. Once the locks are open, lift the bottom of the
handle and rotate the handle counter‐clockwise to release the
2‐point latch.
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.
2.1.2.3
Rear‐Access Panel (Detachable)
The rear‐access panel (Figure 6) can be removed for conve
nient access to the rear of equipment mounted inside Boxer‐16.
The purpose of the access panel is to facilitate equipment ac
cess, cabling, and servicing. The panel is secured with six
tamper‐proof screws (hex‐nut‐in‐cup type for the ‐7HE model
and pin‐in‐hex type for the ‐7HEG model). The panel can be
removed with a either a 216 tool or can wrench (for the ‐7HE
model) or with a special hex wrench (provided with the ‐7HEG
model). With the panel removed, the access hole measures
approximately 25” high by 19.25” wide (see Figure 5).
2.1.2.4
Top/Bottom Mounting Brackets
Two full‐width, heavy‐duty, mounting brackets, one at the top
and one at the bottom of the cabinet, come factory‐installed.
These brackets are typically used to mount the cabinet to a wall
or H‐frame. The top bracket has 7 `keyholes', and the bottom
bracket has 5 mounting `slots'. Use wall‐mounting fasteners with
a diameter of up to
3
/
8
”. The vertical distance between the top
and bottom bracket holes is 39” (between the hole centers).
The
mounting hardware and the mounting surface must be of sufficient
strength, quality and size to support the cabinet plus all equipment
to be mounted in it.
2.1.2.5
Side Lift Ears
The Boxer‐16 cabinet is equipped with two external lift ears or
brackets, one on each side, attached at the top of the cabinet (see
Figure 3). These lift ears can be used to lift the cabinet using lift
equipment, 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,
