Picture 1: Container to store and deploy the parachute
The deployment unit is shown in picture 1 and will store the parachute on the
DJI Matrice M600/pro while flying. It is made out of carbon fiber composites
and uses elastic rubber bands 1 to deploy the parachute automatically in case
of an emergency. The parachute is stored inside the tube covered by a lid 2 at
the top. Only the parachutes leash 3 and the connection hook 4 leads out of
the container.

Picture 2: Mounting plate
The mounting plate is a part which has to get mounted onto the top of the DJI
Matrice M600 /pro and acts as the connecting point between the deployment
unit and the drone as shown in picture 2. On top of the mounting plate there
is a bayonet joint 1 including five golden stripes for the electrical connection
between the deployment unit and the motor cut-off PCB. The wire 2 coming
out of the mounting plate has get passed through from top to bottom of the
center plate. The connector 3 at the end of the wire needs to get plugged into
the motor cut-off PCB.
The two engraved padlock symbols 4 indicate the correct open (left) and close
(right) position when attaching the deployment unit.

Picture 3: PCB to stop the motors from spinning
The motor cut-off PCB (Printed Circuit Board) is responsible for stopping the
motors from spinning in the moment the parachute gets deployed. This safety
feature reduces the risk of the parachute lines getting tangled in the propellers.
The 3-pin connector on the left 1 is an input from the A3 flight-controller
to deploy the parachute manually via the remote-controller from the pilot in
command. This PCB also forces the landing-gear coming down after the de-
ployment to safe the payload located underneath when touching the ground.
Therefor the attached servo-cable 2 has to be connected to the servo of the
landing-gear and the original cable for the landing-gear servo has to be con-
nected to the input socket 3 . The signal interface 4 has to be connected to
the mounting plate and is the main interface to the deployment unit. The PCB
gets power from the drone through the XT30 connector, which needs to get con-
nected to 5 . For additional payload the motor cut-off PCB provides the same
connector at 6

Picture 4: Deployment unit with accessories
As shown in figure 4 the parachute 1 comes wrapped in a plastic cover to
protect it from environment influences (secured by some rubber bands) and
it is equipped with a leash. The plastic cover has to stay around the parachute
canopy when getting loaded into the deployment container to secure a fast and
reliable deployment. At the end of the leash is a metal hook to connect it to the
UAVs frame. Also included are three additional leashes 2 and an other metal
hook. To store the leashes in a safe and clean way a plastic container 3 is part
of the kit. This plastic container has to be placed in the middle of the drone
in a way that the three cutouts point into the directions of the arms there the
parachute is connected.

3 Installation
3.1 Connecting the parachute
1
Use one parachute cord every second arm and
pull it around close to the hinge. Thread one
end of the cord through the other ends loop.
Tighten it well. Take care which three out of the
six arms you will select depending of the loca-
tion of anything mounted on top like the GPS
antennas. After connecting all three arms con-
tinue with step 3.

3
After all cords are hooked up with the arms of
the M600 pick up the small lid of the cords stor-
age box and thread all three cords through the
hole in the center.
Next step is to connect the metal hook with the
three cords. First step is to loop them through
the hole which doesn’t have the opening.

5
Go all the way through the hole until the three
loops are close enough for the hook to go into
it.

Parachute Manual for DJI M600 and M600 pro
Run the hook all the way through the loops of
each cord as shown in step 6.

When done the loops should get tightened to
get a solid and strong knot.
Pull the hook close to the lid. At the end the
push the cords into the storage container run-
ning through the slots at the side. The excess
length of th cords can be placed inside th con-
tainer.

Push the lid on the plastic container to get a
clean and safe installation on your M600. The
finished setup should look like shown in step
no. 9.

3.2 Installing the mounting plate
The installation of the mounting plate is quite straight-forward. First you need
to find a position right above one of the batteries that fits best for your setup.
If your are using the M600 pro version one of the position will not be available
through the bigger top cover in the front. The mounting plate should be placed
at a position with the greatest distance away from critical components like the
GPS antennas. As shown in picture 5 the plate is mounted above battery num-
ber six because the antenna is located between battery two and three. In case of
a parachute deployment the chance of ripping off the antenna gets minimized
because of the positioning.
When mounting the plate you have to remove the two screws right above the
battery. Place the plate above the screw-holes and put back in the screws.
Picture 5: Feasible positions for the mounting plate
After mounting the plate the signal wire coming out of the plate needs to
run down to the bottom where the motor cut-off PCB will get installed.
