Installing the Rack Mount
Mounting steps
On each of the twelve #10-32 panhead machine
screws, first put on a lock washer and then put on a
flat washer.
Using a No. 2. Phillips screwdriver, attach each screw
(with lock washer and flat washer) through the holes
in the rack adapter and into the back of the bezel of
the ET unit.
Tighten each screw to a torque of 12 inch-pounds.
If your unit requires security screws (available as an
option from 3M Touch Systems), insert them.
Pick up the rack adapter with the ET unit attached and
fit it to the rack. Position it to match the locations of
the clips installed earlier.
Fasten the adapter/ET unit to the clip nuts in the rack
with the eight slotted #10-32 x 5/8-inch countersunk
machine screws with a cup washer on each screw.
If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater
than room ambient temperature. Therefore, consideration should
be given to installing the equipment in an environment
compatible with the manufacturer’s maximum rated ambient
To install the rack adapter in the 19-inch rack, follow
these steps:
To determine where to attach the clip nuts to the rack,
hold the rack adapter in the rack where you want to
mount the ET unit. Fasten the clip nuts on the rack so
that they match the locations of the slots in the sides
of the rack adapter.
The clip nuts will “clip” to the rack. Screws and
washers are not required.
Place the ET unit face down on a padded bench or
other protected surface.
Fit the rack adapter over the back of the ET unit,
against the back of the bezel.
