4. Locating and Installing the Indicator
The EDM-900/930 display should be located as close as possible to the pilot with an unobstructed view and for
easy access to the buttons on the instrument. A remote display is also provided for alarm indications directly in front
of the pilot. Installation should be done in accordance with advisory circular AC43.13-1A.
The diagram below should be used as a guide for cutting and drilling the mounting and buttonholes in the
instrument panel. The dimensions shown are for the final cutouts. Allow extra clearance for any panel finish such as
powder coat. The plastic button caps are removable by grasping and pulling each off. The EDM-900 mounts in a
custom 5+ inch cutout and the 930 mounts in a 6x4.5 cutout. The instrument configures itself automatically for 4 or
6 cylinder engines, 14 or 28 volt electrical systems. Mount the indicator using the figure below as a guide. The
Remote Alarm Display PN-790749 mounts in a ½ inch hole in the panel directly in front of the pilot..
