Nesis III — Installation Manual 1. Introduction
1 Introduction
First of all we would like to thank you for purchasing our product. Nesis is
a complex instrument and we strongly recommend reading manuals before
installation. You may be interested in reading:
•Nesis Installation Manual (this manual),
•Nesis User’s Manual,
•DAQU Installation Manual,
•MAGU Manual,
•Autopilot Installation Manual,
•our web page www.kanardia.eu.
This manual assumes that you are familiar with the Nesis user interface sys-
tem.
1.1 Icons Used Trough the Manual
A few icons appear on the side of the manual, which have special meanings:
This icon denotes information that needs to be taken with special
attention. An injury or even death is possible if instructions are
not obeyed.
Failing to follow the instructions may lead to the equipment dam-
age.
This icon denotes background information about the subject.
This icon denotes a tip.
1.2 Warnings
The following warnings and limitations apply during installation.
•Software based fuel flow and software based fuel level can be very danger-
ous and misleading. They affect also range and endurance calculation.
Never trust any of these values. Make sure that you have some reliable
way to check the actual fuel level during the flight.
10 ©Kanardia 2019-2021

Nesis III — Installation Manual 1.3 Minimal System
•Before installing the instrument, you shall carefully read and understand
this manual and any other supplementing manual.
•The manual is not a substitute for an approved aircraft specific main-
tenance manual, installation or design drawing. Attempting to install
Nesis and corresponding equipment by reference to this manual only
(without planning or designing an installation specific to aircraft) may
compromise the safety and is not recommended.
1.3 Minimal System
Nesis minimal system consists of two components: Nesis III display and
DAQU (engine management box). They are sold together as a kit.
This manual starts with the installation instructions for the minimal system
and then adds separate sections for optional components.
Some components have their own installation manuals.
2 Display Installation
This section covers the installation of the Nesis display.
2.1 Placement Consideration
There are several considerations which affect the display position on the in-
strument panel.
•The display must be in direct view field of the pilot without any ob-
structions.
•The display supports landscape orientation only. Portrait orientation is
not possible.
•The display has a modest power consumption. It is cooled trough top
and bottom openings in the housing. Please make sure that cooling air
will be able to circulate trough the housing openings.
•Avoid to place the display next to the heater vents or into any kind of
direct stream of hot air.
11 ©Kanardia 2019-2021

Nesis III — Installation Manual 2.2 Main Display Dimensions
•Monitor the internal display temperature. It must not exceed maximal
internal rated temperature of the display. If this temperature comes
close or even exceeds maximal rated temperature, a cooling system must
be built into the instrument panel compartment, to keep the compart-
ment temperatures low enough.
•The display housing extends behind instrument panel and some extra
space must also allocated for the connectors, cables and tubes. See
Figure 1 for more details.
•The display does not need special harness for the installation. It is
mounted directly to the instrument panel.
•Fix/glue mounting nuts behind the instrument panel for simple instru-
ment removal.
•The instrument panel must be flat. If instrument panel is not-flat,
internal stresses will appear and they may damage the plastic bezel.
2.2 Main Display Dimensions
The display main dimensions are shown on Figures 1 – 3 and Figure 4 shows
the cutout.
The knob and part of the bezel protrude 23.4 mm in front of the instrument
panel. On the back side, the housing requires 41.3 mm space. This space
already includes thickness of the instrument panel. Pito-static connectors
protrude extra 16.9 mm backwards. At least 30 mm is also required for the
cables and pito-static tubing.
The bezel width is 214.3 mm and the height is 174.9 mm. Back side housing
width is 210.3 mm, height 168.9 mm.
Figure 3 shows Nesis top view. Cooling openings are clearly visible. Same
cooling openings are also on the bottom side. It is very importnat that bottom
and top cooling openings are not obstructed – cooling air must freely circulate.
2.3 Cutout
Cut your instrument panel according to your Nesis display size using cut-out
dimensions and cut-out templates. The cut-out drawing can be downloaded
from our web page: www.kanardia.eu/support/manuals/, search for the
Nesis III Cutout.pdf or for Nesis III Cutout.dxf. Please note that the

cutout tolerance was already added to the green cutout line. Figure 4 illus-
trates the cutout dimension.
Some mounting notes:
•The display is mounted from front.
•The display is shipped with a set of mounting hardware (four screws and
nuts). You can replace screws and nuts with more appropriate ones, Do
not use screws with head larger than 5.5 mm in diameter.
•Do not re-drill holes in the bezel.
•Due to highly sensitive multi point touch screen, the bezel had to be
made of non-conductive material – it is made of ABS plastic. Please
be careful. Do not bend the bezel and do not over-tighten the screws.
Bezel corners are especially sensitive.
Print the template on a hard paper. After printing, take a precise ruler or
measuring tape and make sure that printed sizes are correct. This procedure

is necessary, because some printers or PDF rendering software may slightly
adjust the document size, producing wrong cut-out dimensions.
If possible, make a cutout with a CNC equipment. You can use the dxf file
to program the CNC. This will make excellent results.

2.4 Mounting Procedure
Once the appropriate opening is made in the instrument panel, test mount
the display. Adjust the opening if necessary.
There are several ways to fix the Nesis into the panel:
•using supplied M3 nut and lock washer,
•using self-clinching nut insert,
•using threaded rivet nut insert,
•using spacer stud and epoxy.
Details are shown in next subsection.
15 ©Kanardia 2019-2021

Nesis III — Installation Manual 2.4 Mounting Procedure
2.4.1 Fixation with Supplied M3 nut and Lock Washer
This is the most straightforward method of fixation. Figure 5 shows an ex-
ample.

○M3 bolt with head colored black.
4
○External teeth lock washer.
5
○Standard M3 nut.
Please do not use excessive force on M3 bolt/nut to avoid damage of plastic
bezel.
This fixation principle has one disadvantage – it makes Nesis service removal
a bit difficult as nut on the back side may be difficult to access.
2.4.2 Fixation with Self-Clinching Nut
Instead of using standard nut and lock washer, a self clinching nut may be
used. They come in various forms, which depend on the instrument panel
material. Some special tools like arbor press may be required.
For instrument panels made of aluminum, a nut like shown on Figure 6 can be
used. The nut must be pressed into the panel before installing the instrument.
16 ©Kanardia 2019-2021

Nesis III — Installation Manual 2.4 Mounting Procedure
Once pressed, the nut shall not turn when Nesis is removed and this makes
servicing easier.
The hole size needs to be as accurate as possible. It is recommended to do a
few tests on a scrap part first.

2.4.3 Fixation with Threaded Rivet Nut Insert
Threaded rivet nut inserts (a.k.a. rivnuts) may be also used, especially on the
composite and thin panels. Again, they come in various forms. Some special
riveting tool is needed to fix the threaded rivet.
Get some aluminium M3 rivnuts. Drill a hole into the panel, as it is required
by the rivnut used. Then use the rivnut tool to fix the inserts. Be gentle, as
there is only minimal panel material between hole and the cutout chamfer.
Figure 7 shows an example.
There is a small disadvantage using rivnuts. As the rivnut head has some
minimal thickness, the Nesis bezel will probably not mount flush with the
panel – there will be a small gap.

2.4.4 Fixation with Spacer Stud and Epoxy
As another alternative, a M3 nut can be epoxied to the back of the instrument
panel. Standard M3 nut is a bit too small to be epoxied successfully. Thus a
M3 spacer stud at least 6 mm in length shall be used instead.
1. The spacer surface shall be made rough using coarse sandpaper. If
spacer is coated, the coat shall be removed. A dremel tool comes handy.
2. Sand the back side of the panel where epoxy will be applied. Surface
must be dull.
3. Mix a small batch of epoxy together with some cotton flox or with milled
glass fibers. These add strength and also increase viscosity, which makes
epoxy application easier.
4. Apply a tiny amount of oil or grease on bolt thread. This will prevent
strong bond between epoxy and thread if epoxy is applied over the bolt
thread by accident. But be careful not to put any grease on the surfaces
where epoxy must be applied.
5. Fix spacers in place using M3 bolts and apply the epoxy mix around
the spacers.
6. Wait for epoxy to cure.
This fixation principle is a bit messy, but works very well in practice.

3 Power Installation
Nesis power input requirements are compatible with 12 and 24 V aircraft
power systems. Nesis accepts 10 – 30 V range.
The supplied power cable have two unterminated wires. The red wire must be
connected to the power (+12V or +24V) terminal. The blue wire connects to
the ground terminal. The other side of the power cable has a plastic connector.
This connector has a hook next to the red cable. Insert the connector into
Nesis at the back. The notch and the hook must match – they prevent wrong
cable orientation, see Figure 9.
When a slave Nesis is also connected to the system, it is powered with its own
power cable.

19 ©Kanardia 2019-2021

Nesis III — Installation Manual 3.1 Circuit Breaker
•two female crimp terminals . . . W¨urth Elektronik, PN 649 006 137 22,
•0.75 mm2(about AWG 18) red and blue leads.
The terminals have finitive number of mating cycles. They belong to the 25
mating cycles quality class.
3.1 Circuit Breaker
The power input must be routed trough a circuit breaker. Nesis consumes
about 800 mA at 12V on full brightness. Various peripheral devices (Daqu,
Magu, Indu, etc.) are powered via Nesis and they add to total consumption.
A rough estimate is 250 mA per device.
So a circuit breaker rated at 1.5 to 2.5 A is needed for the systems with one
Nesis. In the case of two Nesis connected to the same circuit breaker, use 2.5
to 3.5 A rated circuit breaker instead.
It is recommended that each Nesis gets its own circuit breaker.
3.2 Aircraft Master Relay
Please make sure that aircraft master relay (in fact all relays) have a protection
diode (a flyback diode)1, which protects against voltage spikes. A coil in relays
without this diode may cause spikes that exceed 100 V and they propagate
on the system bus. Such spikes may cause permanent damage on Kanardia
equipment and other avionics.
3.3 Backup Battery
This backup battery solution works only on 12V systems.
Nesis may be powered via an optional external backup battery system called
UPSU. The backup system consists of electronic circuit UPSU, a simple lead
VRLA AGM battery (1.2 Ah is typically used) and a DPDT (or DPST)
switch. Figure 10 shows the schematics.
The Nesis system is switched on/off by a double pole switch. This switch
turns on/off two circuits at the same time. The first one brings system power
into UPSU and the second one brings backup battery power into UPSU. When
there is enough voltage present on the system bus, system power is used and
