Installing 429 Module/ADAHRS/EMS-220 to HDX1100 Tray

[dratte]

Referring to 103261-000 Rev E (HDX Installation Manual) page 19 and 21, the EMS Module, ADAHRS Module, and ARINC429 modules stack and are attached to the Avionics tray.

I have two brackets, one being 503402-000 (can't find any info) and 503102-000 that per the Dynon website is EMS-to-ADAHRS/ARINC Mounting Plate.

The Installation manual does not reference these parts nor the proper hardware for installation. None was included in the packaging. What should it be?

Also, what appears to be obvious is bolting to the pattern of each device lower in the stack, but this requires removing tamper seals that void the warranty - this seems illogical that the standard installation would void the warranty.

Lastly, the co-pilot display shows on page 21 the battery being installed on the Avionics tray, but the tray does not have any hole pattern matching the battery at the specified location. Obviously one could drill and install PEMs, but it seems like this is a well thought out item since it already has PEMs in many locations so I figure it is wise to inquire prior to doing such as this is a certified installation and must be installed IAW the manual.

Can anyone clarify please?

I don't have the brackets in front of me, but I remember one being for the ammeter shunt that was not referenced anywhere. I did not use the bracket.
The co-pilot avionics tray does not fit in a Bonanza, not sure what aircraft you have.
They show leaving the screw out rather than going into the tamper seal.

Only install three screws.
