Dovetailing Procedure
Basler H1 cases can be interlocked by means of
a tenon and mortise on the left and right sides of
each case. The following paragraphs describe
the procedure of dovetailing two cases. Figure
12-12 illustrates the process.
Step 1. Remove the drawout assembly from
each case by rotating the two captive, front
panel screws counterclockwise and then sliding
the assembly out of the case. Observe
electrostatic discharge (ESD) precautions when
handling the drawout assemblies.
Step 2. Remove the mounting bracket from the
side of each case where the two cases will
mate. Each bracket is held in place by four
Phillips screws.
Step 3. The rear panel must be removed from
one of the cases in order for the two cases to be
joined. On that panel, remove the Phillips
screw from each corner of the rear panel except
for the screw at the upper lefthand corner (when
looking at the rear of the case). This screw is
closest to Terminal Strip A.
Step 4. Turn the screw nearest to Terminal Strip
A counterclockwise until the rear panel can be
removed from the case. If you have difficulty
removing this screw, use the alternate method
described in Step 4a. Otherwise proceed to
Step 5.
Step 4a. Use a Torx® T15 driver to remove the
two screws attaching Terminal Strip A to the
rear panel. Remove the terminal strip and set it
aside. Remove the remaining Phillips screw
from the rear panel and set the rear panel
aside.
Step 5. Arrange the two cases so that the rear
dovetailed edge of the case without a rear panel
is aligned with the front dovetailed edge of the
case with the rear panel installed. Once the
dovetails are aligned, slide the cases together.
Step 6. Position the rear panel on the case from
which it was removed. Make sure that the panel
orientation is correct. Perform Step 6a if
Terminal Strip A was not removed during the
disassembly process. Perform Step 6b if
Terminal Strip A was removed during
disassembly.
Step 6a. Position the rear panel over the case
and align the screw closest to Terminal Strip A
with its mating hole. Tighten the screw while
maintaining proper alignment between the rear
panel and case. Finish attaching the panel to
the case by installing the remaining three
Phillips screws. When installed, the rear panels
prevent the two cases from sliding apart.
Step 6b. Align the rear panel with the case and
install the four Phillips screws that hold the rear
panel in place. Position Terminal Strip A in its
panel opening and replace the two Torx® T15
screws. When installed, the rear panels prevent
the two cases from sliding apart.
Step 7. Mount the case assembly in the
desired rack or panel opening and reinstall the
drawout assembly in each case.
