Electronics International MVP-50T - Manual (Page 18)

2.2 Review the "EDC Wiring Work Sheets:"
There are a number of probes and extension cables that will need to be installed. The key to keeping the
installation simple is to organize the work using the "EDC Wiring Work Sheets"
"EDC Wiring Work Sheets" "EDC Wiring Work Sheets" "EDC Wiring Work Sheets" "EDC Wiring Work Sheets" supplied with this kit.
Review the functions assigned to each EDC input on the EDC Wiring Work Sheets. The work sheets are
prepared at the factory with the functions and probes already assigned.
2.3 Verify Your Have all the Probes, Modules, Transducers and Cables:
The three EDC 37-pin D-sub connectors and the MVP 25-pin D-sub connector are pre-wired at the fac-
tory. The three EDC connectors are marked Top, Middle and Bottom. The EDC Wiring Work Sheets
provide a list of the probes supplied with this kit.
A. Check that you have all the probes listed on the EDC Wiring Work Sheets.
B. Check that the three EDC 37 pin-D-sub wire harnesses are provided with the proper wires for
each of the probes shown on the EDC Wiring Work Sheets.
C. Check that the MVP 25-pin D-sub wire harness is provided.
2.4 Installing the MVP Display:

one of two ways, depending on convenience or the installer's preference. The first method is the traditional
method of installing the MVP display from behind the panel. An aircraft
panel cutout drawing is provided at the back of this manual.
The second method is more suitable when an MVP display is to be mounted
in an existing aircraft panel. This method requires creating a sub-panel
slightly larger than the MVP display. The MVP display is mounted in the
sub-panel and the sub-panel is mounted on the front of the existing aircraft
panel. This allows the installer to rough-cut a hole in the aircraft panel to
accommodate the MVP display. The sub-panel covers any imperfections in
the cut hole. Also, the MVP display may easily be removed from the front
of the aircraft panel.
The sub-panel should be made from .062" (or thicker) aluminum and can be
painted black or the same color as the aircraft panel. Four screws (6-32 or
larger) located at the top and bottom of the sub-panel should be used to mount the sub-panel to the aircraft
panel. If there is no room at the top and bottom for mounting screws, they may be placed on the sides of
the sub-panel.
CFR 23.1321(a) states, “Each flight, navigation, and powerplant instrument for use by any required pilot
during takeoff, initial climb, final approach, and landing must be located so that any pilot seated at the
controls can monitor the airplane’s flight path and these instruments with minimum head and eye move-
ment.” AC 23.1311-1B provides one method (but not the only method) of complying with this CFR. AC
23.1311-1B recommends a powerplant instrument be installed within a distance of 21" from the pilot’s
visual centerline to the middle of the instrument. The pilot’s visual centerline is a perpendicular line from
