Before installing the battery enclosure, the flanges must be assembled with their end caps and o-
rings. The front battery flange is shown at picture 3.
First of all, apply a little amount of silicon grease on the o-rings.
Use the screws for installing the end caps.
It is important to avoid the presence of any particles or dust on the o-rings.

Paso 10 — Mid clamps assembly
Now, introduce the M3x18 screws to join the mid clamps and the lower clamps.
Using the upper hole of the mid clamp it will be easier (picture 1).
A small deviation of the clamps' holes may block the nut. If this is your case, you can introduce the
screw from the bottom.
Paso 11 — Assembling the float to the top sub-assembly
2 x R6 - 7/8 Screws (Bag 1)
4 x R8 - 1" Screws (Bag 9)
Put the top sub-assembly on the frame (without screws).

Paso 12 — Assembling the float to the top sub-assembly
Put the float on the top of the frame. Use the R8 - 1" screws on the hloles marked in the picture 2.
The orientation of the float is the following (picture 3)
Red arow: front
Blue arrow: Rear
Paso 13 — Frame finished
The frame is finished, lets continue
with the electronics and thrusters
assembly.

Paso 14 — Electronics Assembly. For PCB's model 0.4 (white PCB's) go to next step.
First of all, lets install every penetrator to the rear electronics end cap.
Put a little amount of silicon grease on every penetrators' o-ring.
At the picture 2, a diagram o the thrusters connection is shown. Check carefully the numeration of
each thruster which defines the position in the frame, and into the end cap.
At the picture 3 you can see the rest of the penetrators layout.
When installing the lights penetrator, the black connector must be removed from the yellow cable.
Pull up the tab carefully and pull the cable out. After introducing the penetrator, put it back again.
In order to introduce the battery cable, pass one wire first and then the other. They may be difficult
to introduce into the nut. If necessary, remove the heat-shrink and put it back again after installing
the penetrator.
Motor configuration varies depending on the PCB model of your Nano. If your Nano has the PCB
model 0.4, please follow the next step for the right thruster configuration.

Paso 15 — Thruster assembly for PCB's 0.4 (white PCB's)
Please follow this scheme for a right
motor configuration in PCB's model
0.4 (white PCB's).
Paso 16 — Penetrator installation
The installation of each penetrator must be done as follows:
Put the o-ring into the slot of the penetrator's head.
Install the penetrator in the end cap, and the nut in the other side.
After installing all the penetrators, the end cap should look like the pictures 2 and 3.
Don't forget the silicon grease into every o-ring, this will ensure a longer life and perfect water
tightness.

Paso 17 — Installing the end cap into the flange
6 x M3x14 Screws (Bag 3)
In this step the electronics end cap is installed into the flange
Consider the orientation of the flange (picture 2). One of the 4 inner holes must match with one of
the 6 outer holes in the upper side of the flange.
Paso 18 — Electronics assembly
Now it is the time to connect everything to the brain of your Sibiu Nano.
The position of the electronics is like shown at the pictures, with the Raspberry on the left, and the
Pixhawk on the right.

Paso 19 — Thruster connection (except for PCB's 0.4)
For the thrusters, each one has 3 wires. You have to connect each one to the corresponding port.
In the picture 1, you can see the port of every thruster attending to their numeration and their
position from the end cap.
In the second picture, the sequence of the wires for each motor is shown. The thruster 3 is inverted
from the rest of the motors.
In the picture 3 you can see the final look of the connections.
This step can be more confortable if you remove the ESCs that are close to the connectors.
For PCB's 0.4 refer to the next step.

Install the second vent plug and the
other tip of the battery cable in the
battery endcap. To insert the battery
cable follow the same procedure
mentioned in the Step 14.
Paso 23 — Connecting the pressure sensor and the lights
The pressure sensor is connected to the I2C port of the Pixhawk (picture 1).
If you have Lumen lights, pictures 2 and 3 show how to connect them.
Connect the red and black wires to the blue terminal block next to the motors terminals. Red to
"PM" and black to "GND".
Then, connect the yellow wire to the to the "Lights" terminal next to the Pixhawk (picture 3).
