Physical Installation
The diagram below shows the mounting dimensions of the backup battery.
Figure 59 – SV-BAT-320 Mounting Dimensions
Dynon does not provide mounting hardware for use with the SV-BAT-320. The mounting tabs
on each side of the module have holes sized for #8 fasteners. Button head style AN hardware is
recommended as spacing between the holes in the tabs and the body of the enclosure limits
what style tool can be used to tighten certain fasteners. Follow recommended torque practices
when tightening the mounting hardware.
The SV-BAT-320 enclosure is made of plastic that may crack if too much torque is
applied to the fasteners and the mounting tabs of the SV-BAT-320. The
appropriate amount of torque that should be applied is a combination of the
mounting base material, its thickness, the fastener, the presence or absence of
thread lock compound on the fastener, and the tolerance stack up of the
diameters of the mounting hole and the fastener. Apply sufficient torque that the
fasteners will not self-release, but not so much that the mounting tabs will
eventually break from too much stress.
Use of ferrous fasteners in this location is acceptable. Do not rivet the SV-BAT-320 to the
aircraft as this will hinder future removal if necessary.
