COMSPHERE 3000 Series Carrier
To install the carrier in a cabinet that does not have
.
threaded screw holes:
Procedure
1. If the carrier is to be installed in a 23-inch cabinet,
you must reverse the mounting brackets. To do
this, remove the screws that attach the mounting
brackets to the sides of the carrier, then reverse the
brackets and replace the screws.
2. Position the carrier in the cabinet and determine
the front rail holes to be used.
3. Slip a speed nut onto each rail hole selected, as
shown in Figure 3-4, and align the hole of the
speed nut with the hole in the rail.

4. Line the carrier mounting bracket up with the
speed nut, and start to screw the speednut screw
into the carrier mounting bracket and the speed
nut. Start all four screws, then tighten all four until
the screw head is flush with the carrier and it is
securely mounted in the cabinet.
5. Install the next carrier in the same manner (from
the bottom up) using Steps 1 through 4. Up to six
carriers can be installed in a cabinet (Figure 3-5).
6. If installing a carrier below existing carriers in a
cabinet, it is possible that there will be insufficient
vertical space to align with the holes in the
mounting bracket. In this case, install the four
machine screws directly through the holes in the
mounting brackets and screw them firmly into the
tapped holes in the mounting rails.
