Safety Precautions
Safety Precautions
⚫Read these instructions carefully before you install, operate, or transport the
system.
⚫Install the system or DIN rail associated with, at a sturdy location
⚫Install the power socket outlet near the system where it is easily accessible
⚫Secure each system module(s) using its retaining screws
⚫Place power cords and other connection cables away from foot traffic. Do not
place items over power cords and make sure they do not rest against data
cables
⚫Shutdown, disconnect all cables from the system and ground yourself before
touching internal modules
⚫Ensure that the correct power range is being used before powering the device
⚫Should a module fail, arrange for a replacement as soon as possible to minimize
down-time
⚫By means of a power cord connected to a socket-outlet with earthing connection
⚫This product is intended to be supplied by a Listed Power Adapter or DC power
source, rated up to 5000m altitude operation. If further assistance is required,
please contact Neousys Technology
⚫If the system is not going to be used for a long time, disconnect it from mains
(power socket) to avoid transient over-voltage
Battery Warning
⚫Batteries are at risk of exploding if incorrectly installed.
⚫Do not attempt to recharge, force open, or heat the battery.
⚫Replace the battery only with the same or equivalent type
recommended by the manufacturer.

Service and Maintenance/ ESD Precautions
Service and Maintenance
⚫ONLY qualified personnel should service the system
⚫Shutdown the system, disconnect the power cord and all other connections
before servicing the system
⚫When replacing/ installing additional components (expansion card, memory
module, etc.), insert them as gently as possible while assuring proper
connector engagement
ESD Precautions
⚫Handle add-on module, motherboard by their retention screws or the module’s
frame/ heat sink. Avoid touching the PCB circuit board or add-on module
connector pins
⚫Use a grounded wrist strap and an anti-static work pad to discharge static
electricity when installing or maintaining the system
⚫Avoid dust, debris, carpets, plastic, vinyl and
8
tyrofoam in your work area.
⚫Do not remove any module or component from its anti-static bag before
installation
Restricted Access Location
The controller is intended for installation only in certain environments
where both of the following conditions apply:
⚫Access can only be gained by QUALIFIED SERVICE PERSONNEL who have

1 Introduction
NRU-52S is a rugged, wide temperature, fanless edge AI computer delivering 21 TOPS for
AI-based video analytics applications requiring H.264/H.265 video decoding and real-time
inference. Power by an NVIDIA® Jetson Orin™NX/ Xavier™NX system on module (SoM), it
comprises of NVIDIA® Ampere GPUs (Orin NX), CUDA cores, Tensor cores, and NVDLA
(NVIDIA® Deep Learning Accelerator).
Benefiting from the power-efficiency of NVIDIA® Jetson Orin™NX, which consumes only 25W
of power, NRU-52S+ can decode up to 18 streams of 1080p video at 30 FPS, and also offer
100 TOPS inference performance. The high AI performance per watt makes NRU-52S+ ideal
for applications with a limited power source, such as in a robot, vehicle, or rolling stock. Also,
with Neousys' industrial-grade thermal design, NRU-52S+ is ideal for edge deployments that
require fanless wide temperature operations, such as at roadside, wayside, construction site,
agriculture, or in a dusty factory.
NRU-52S+ offers four IEEE 802.3bt PoE++ ports, each port can supply up to 90W to IP
cameras or PTZ speed dome cameras for AI-based detection, tracking, and recognition
applications. NRU-52S+ also offers flexible expansions with two mPCIe sockets for NVMe
storage, WIFI, GNSS, or V2X module; one M.2 B key for 4G LTE or 5G NR module with
dedicated passive thermal design, and a total of five antenna holes for mobile broadband.It also
has one hardware configurable RS232/RS422/RS485, 1x GPS PPS input, 3-CH isolated DI,
and 4-CH isolated DO for communication with external devices.
By integrating PoE++ connectivity, 100 TOPS inference performance, a vast of NVIDIA AI
JetPack toolkits, NRU-52S+ can enable more possibilities for real-time video analytics such as
autonomous machines, security alerts, law enforcement, and V2X applications. With its -25°C
to 70°C fanless operation, wide-range DC input, ignition control, and 4G/ 5G connectivity,
NRU-52S+ is not only for indoor/ stationary installations but also ideal for harsh edge
deployments.
