The Indemnis Nexus M200 Parachute Recovery System (Nexus M200 PRS) for the DJI Matrice 200 Series is an advanced ballistic
safety system designed to protect life and property on the ground and enable advanced ight operations by reducing the
drones level of kinetic energy in the event of a failure. This manual explains installation instructions and how the Nexus M200
PRS works and how to properly operate the system both on the ground and in the air. The Nexus M200 PRS should only be
used by trained pilots with authorization to y near or over people.

SAFETY PRECAUTIONS
|
PAY ATTENTION
Using the Nexus M200 PRS does not eliminate all risk associated with operating a drone
near or over people. Pilots should ensure they are operating in accordance with the rules
and regulations of the Civil Aviation Authority (CAA) of the operating location.
The Nexus M200 PRS is designed to deploy in less than 14 milliseconds by releasing
compressed gas into a tube and launching a parachute ballistically at over 140 MPH.
WARNING: Do not lean against, press, drop, or stand directly in front of the red cap of the
system, or point the system in any direction that may cause harm, injury, or damage to
life or property in the event of a ground deployment.** Operators shall disarm and turn
the system off immediately after landing BEFORE handling the aircraft.
**While the Nexus M200 PRS has multiple electronic and software-based safeguards
to prevent the possibility of an accidental or inadvertent deployment on the ground, it
should be noted that the Nexus M200 PRS deploys from the top of the aircraft where the
RED CAP is located. It is recommended that the operator maintains a clear area of 8
meters from the Nexus PRS when the system is powered on.

HARNESS AND ARM BRACKETS
Attaching the Nexus M200 Parachute
Harness and Arm Brackets
(ONE-TIME INSTALL):
There are two parachute harness and arm bracket assemblies. The arm
brackets are designed to strengthen the M200 articulating arm joints during a
deployment and to attach the parachute to the M200 for a level landing orien-
tation. The parachute harness that has a single bolt hole in each arm bracket
goes on the front of the aircraft, while the parachute harness that has two bolt
holes on each arm bracket goes on the back of the aircraft. Each harness has
an extended line section outside of the black sleeve cover that has a quick
link on it. This side of each harness will be oriented to the right side of the
aircraft as viewed from the back.
To install the FRONT PARACHUTE HARNESS assembly:
1) Place the DJI M200 in front of you so that you are looking at the front of
the aircraft, with the back end furthest away from you.
2) Unlock and loosen the DJI M200 twist arm lock (2A) on the front two
arms so that the arms remain in the ready-to-y position but are not
secure (2B) . With a 7mm socket and wrench, remove the arm pivot bolt
from each of the front arms (2C).
3) Take the Nexus front parachute harness (with only one bolt hole in each
arm bracket) and place the arm bracket WITHOUT the line extension on
the left front arm of the aircraft which will be on your right side. The
arm bracket is designed to slip over the M200 arm joint so that the bolt
holes line up.

4) The other front arm bracket can now be slipped over the right arm joint
of the aircraft, on your left side, with the line extension and quick link
hanging down by the right landing leg of the aircraft
5) Install the provided M4 arm bolts (5A) once the bolt holes on both brackets
are aligned with their respective arm joints on the M200. Secure each
bracket bolt with the provided M4 nuts and tighten (5B) to a secure t
so that the nut face is ush with the Nexus arm bracket.
6) The M200 twist arm locks on the front arms can now be secured for ight
or stowed for travel like normal.
7) Using the provided mounting tape, place it along the M200 body just
under the area where the INDEMNIS logo cable wrap sits securing it rst
to the surface, then peeling the backer off and pressing the cable wrap
rmly onto the tape.

HARNESS AND ARM BRACKETS
To install the BACK PARACHUTE HARNESS assembly:
1) Place the DJI M200 in front of you so that you are looking at the back of
the aircraft, with the front end furthest away from you.
2) Unlock and loosen the DJI M200 twist arm lock on the back two arms so
that the arms remain in the ready-to-y position but are not secure.
With a 7mm socket and wrench, remove the arm pivot bolt from each of
the back arms.
3) Take the Nexus back parachute harness (with two bolt holes in each
arm bracket) and place the arm bracket WITHOUT the line extension on
the left back arm of the aircraft which will be on your left side. The arm
bracket is designed to slip over the M200 arm joint and the bracket
should be slid over the arm joint as far as possible so that the inner
most bolt hole lines up with the arm joint.
4) The other back arm bracket can now be slipped over the right arm joint of
the aircraft, on your right side, with the line extension and quick link
hanging down by the right landing leg of the aircraft.

FLIGHT TERMINATION SYSTEM
(
FTS
]
Attaching the Nexus M200 Flight
Termination System
(ONE-TIME INSTALL):
The Nexus FTS is designed to attach to the back arm parachute harness arm
brackets at the remaining two bolt holes. The Nexus FTS will extend into
the cavity above the battery release mechanism on the aircraft. There is a
manual release lever on the Nexus FTS as well as a battery catch that pre-
vents the batteries from leaving the airframe in the event of a Nexus FTS
activation. The battery catch lever can be depressed in conjunction with the
battery release lever to quick swap M200 aircraft batteries. The Nexus FTS
is a one-time install and is attached via wiring harness to the ATS Housing.
To install the Nexus M200 FTS:
1) Slide the Nexus FTS into the Nexus parachute harness arm brackets at
the back of the aircraft such that the Nexus FTS mechanism is extended
into the cavity above the aircraft battery release mechanism. The wiring
harness should t and be routed between the FTS structure and aircraft
body.
2) Line up the bolt holes of the Nexus FTS structure and the Nexus
parachute harness arm brackets.
3) Insert and secure the provided M4 bolts through the arm brackets and
Nexus FTS structure and secure with the provided M4 nuts. Tighten the
M4 nuts to a secure t so that the nut face is ush with the Nexus
arm bracket.

Attaching the Nexus M200 Leg Bracket and
Automatic Termination System
(ONE-TIME INSTALL):
The Indemnis M200 Nexus PRS ATS is attached to a leg bracket that will re-
main rigid on the aircraft in the event of a deployment. The leg bracket will be
placed onto the right side of the aircraft. This will be a one-time install. The
FTS is attached to the ATS via a wiring harness.
To install the Nexus M200 ATS:
1) With the provided 2mm hex driver, remove the right DJI M200 leg
bracket by unscrewing the three M3 screws. Save the M3 screws in
a safe place in the event that you remove the Indemnis M200 Nexus PRS
system from the aircraft.
2) Take the DJI leg bracket and place it into the Indemnis leg bracket and
ATS assembly.
3) Install the Indemnis leg bracket and ATS assembly onto the aircraft with
the provided M3 screws and DJI leg bracket. The screws should be
tightened to a snug t such that the Indemnis leg bracket sits ush on
the body of the aircraft.
4) The DJI leg may now be installed and removed normally. The
Indemnis ATS housing will y with the aircraft in the event that the
Nexus tube is not attached.
