3Introduction
The DRS-M600 is approved for the DJI M600 series including the professional version (M600
pro) with any additional payload as long as it is operated within the specifications provided by
the manufacturer DJI. It provides the following advantages:
•UAV-independent sensors
•Very light-weighted
•Easy to reuse within minutes
•Visual and acoustical indication signals
•No use of pyrotechnics/explosive components to deploy the parachute
•No use of compressed gas cartridges to deploy the parachute
•Bayonet mechanism to simply attach and detach the whole system
This document will guide you through the system components, installation, configuration and
pre-flight checks as well as possible firmware updates, storage and maintenance
recommendations.

5Installation
Unmount all propellors and detach all batteries and other power supplies before starting the
installation!
Caution:
Mounted propellors may cause injuries or damages.
Caution:
It is mandatory to verify the correct operation with an assembly test right after the
installation! See chapter 5.6 Assembly test for details.
Install the M600 connector
First, you need to install the DRS M600 connector, which will carry the container later, in one
of the five possible positions. There is no general rule which one to use because the
arrangement of superstructural parts like GPS antennas and other equipment can vary
between the different drone models. The key is to find a spot with enough space around it so
that neither the container nor the attached cords will interfere with drone parts. Note that all
cords will rapidly be tautened when the parachute is deployed. No drone parts should be
ripped off in this case.
Each possible spot is right above a battery slot as shown in Figure 1.

Secondly, you need to install a communication cable which is required to allow the remote
pilot in command to manually deploy the parachute via the remote controller. Therefore, a
connection between the DJI A3 flight-controller and the motor cut-off PCB has to be installed.
As an example the port F3 of the A3 flight-controller can be used, but you may choose another
port which is appropriate for your application.
Execute the following steps to install the DRS M600 connector:
•Remove both caps at the top and the bottom of the UAV.
•Choose a position to mount the DRS M600 connector and remove the two screws
within the green marking (see picture below).
•Remove the protection sheet from the adhesive tape on the bottom of the DRS M600
connector
•Place the DRS M600 connector into the chosen spot and use the two connector-screws
included in the DRS accessory to install it. Do not use the original screws because they
are too short.
•Press the DRS M600 connector on the drone to facilitate a good adhesion.
•Install the long RC cable included in the DRS accessory from the A3 flight controller’s
port of your choice (e.g. port F3) through the openings in the center to the bottom of
the UAV (see Figure 2 and Figure 3).

•Feed the cable of the DRS M600 connector through a nearby slit in the M600’s top cap
in order to prevent it from being crimped when the cap is reattached. Then feed it
through the openings in the center to the bottom of the UAV.
•Reattach the top cap.
Install the motor cut-off PCB
The motor cut-off PCB is installed at the UAV’s bottom and is best done with the UAV flipped
over. Consider how to place the UAV without breaking any equipment like GPS antennas.
Place the M600 in a stable upside-down
position and move the landing gear up
manually in order to easily access the
bottom area. Unplug the XT30 socket
which powers the landing gear’s servo.
Remove the bottom cap if not already
done yet.

Remove the six screws from the
terminals which lock the red (positive)
and black (negative) power supply cables
for the motors as indicated by the red
arrows. Unplug only the red wires and
leave the black ones at its original
position.
Place the motor cut-off PCB in the center
with the white arrow (next to one of the
screw holes) facing into the forward
flight direction. Feed the landing gear
servo’s power supply cable through the
intended hole in the PCB when doing
this. Pay attention not to crimp any
cables between the motor cut-off PCB
and the UAV. All six red power supply
cables, the cable coming from the DRS
M600 connector on the top, and the long
RC cable from the A3 flight controller need to stick out from under the PCB.
Ensure that the screw holes of the PCB
and the UAV’s power distribution board
are aligned. Screw the PCB on and fix the
black wires (negative supply) in their
original positions in doing so. Use six of
the PCB-screws included in the DRS
accessory instead of the original screws.
Also use the delivered flat washers to prevent
damages to the PCB as well as the safety washers to
prevent the screws from loosening through vibrations.
Caution:
The safety washer must be put between the cylinder head of the
screw and the flat washer! Ensure a clean surface of the flat washer's
bottom and the PCB.
