To mount the enclosure on a flat surface:
1
Select a convenient mounting location on a wall.
2
Remove the enclosure base mounting bracket from the mounting bracket by removing the four bolts that
connect each side plate (see
).
3
Position the mounting bracket against the wall and mark the location of the four outside mounting holes. Place
the mounting bracket out-of-the-way.
4
Drill four

-inches (6.35 cm) deep at the locations marked in Step 3.
5
Start an anchor bolt in each of the two top matched bolt mounting slots and tighten the bolts into the wall
approximately two-thirds of an inch of the bolt length.
6
Insert the anchor bolts into the two bottom holes located on the outside of the mounting bracket and tighten
the bolts into the bottom two holes of the mounting bracket.
7
Secure the enclosure bracket to the wall by tightening all anchor bolts.
8
Reattach the enclosure base mounting brackets to the mounting bracket with the four sideplate bolts and
torque the mounting bracket bolts between 30 and 40 inch-pounds.
9
If the cable stub connects to an underground cable, dress the cable down the wall to the splice case. If the
cable stub connects to an aerial cable, form a drip loop in the cable and dress it up the wall to the splice case.
Rack Mounting
Use the procedure below when mounting the enclosure in a rack. Have the following equipment ready before you
begin:
•
Four
3

-inch thru-bolts for rack mounting
•
Four

/
8
-inch nonmetallic washers. Nonmetallic washers are required to avoid a ground loop that may result
if both the rack and the enclosure are grounded. ADC does not recommend using the rack ground for the
enclosure ground since its integrity is not one-hundred percent reliable.
•
One wrench
1
Select a convenient location on the cable rack.
2
Position the enclosure so that the outside slots and holes in the mounting bracket align with the mounting
holes in the cable rack.
Because of the weight and size of the enclosure, you may want to remove the dome before
mounting the enclosure. The enclosure must be mounted vertically. A shady location is also
preferred to minimize thermal stress. Refer to
and
for
thermal load capacity information.
While mounting the enclosure, hold it securely to prevent personal injury or damage to the
enclosure.
