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 198 illustrates the
process.
Step 1: Remove the draw-out 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 draw-out 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 left-hand 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 draw-out
assembly in each case.
