Dynon does not include mounting hardware for use with the SV-EMS-220/221. The mounting
tabs on each side of the module have holes sized for #10 fasteners, but it is up to the installer
to decide how the EMS will be secured to the aircraft. Use of ferrous fasteners in this location is
acceptable as the EMS is not adversely affected by small magnetic fields. Dynon recommends
button head style AN hardware as spacing between the holes in the tabs and the body of the
enclosure will limit what style tool can be used to tighten certain fasteners. If you will be
installing dual SV-EMS-220/221s, it is acceptable to stack the two units. Follow recommended
torque practices when tightening the mounting hardware. Do not rivet the SV-EMS-220/221 to
the aircraft as this will hinder future removal if necessary.
