Element-U User Manual
Introduction
This manual provides instructions on safety and installation of
the Element-U, including information regarding security,
specifications and certifications.
Element-U is a battery-powered, wireless sensor that continuous-
ly monitors the real-time availability and usage of any powered
instruments. The Element-U comes with a custom clamp and two
thumbscrews that secures to most power cables. Installation
does not interrupt the electrical chain and can even be done
safely while the machine is on. Usage data is securely transmitted
to the Elemental Machines Insights Dashboard™ where it is
analyzed as the software digitally records and visually shows the
usage timeline and percentage. The Usage Platform empowers
agile lab operations to help guide the service, movement,
efficiency, and purchase of lab equipment to optimize operating
resources.
Safety Information
Batteries
WARNING: the Element-U, Model EU2 is powered by 2
non-rechargeable AA lithium batteries. These batteries can
explode or leak and cause burns if installed backwards,
disassembled, charged, or exposed to water, fire, high tempera-
ture or rapid warming from extremely cold temperature.
For this reason it is important that this Element-U does not
exceed its operating limits in temperature of 5 to 45°C and in
humidity of 0 to 95%RH (non-condensing).
Non-ionizing Radiation exposure
Element-U sends measurements to a Gateway using a low-power
2.4GHz wireless network. When transmitting, the radio module
inside the Element-U works at a maximum power of 8 dBm (6.3
mW). This level is not recognized as hazardous but several
nations (e.g. Canada, Australia) advise not to use such a device
within 20cm of your body i.e. as a personal electronic device
without further precautionary testing.
This equipment has been tested and found to comply with the
USA’s (FCC) limits for a Class B digital device, which are designed
to provide reasonable protection against harmful interference
when the equipment is operated in a residential installation. If
not installed and used in accordance with this User Manual, the
Element-U may possibly cause harmful interference to other
radio communications. Possible remedies for any such interfer-
ence include reorienting the receiving antennae, increasing the
separation between affected equipment and Element-U, or
connecting the affected equipment into an outlet on a circuit
different from that to which the Element-U is connected.
Model EU2
Protecting the Environment
Element-U is designed with consideration for the environment
and complies with relevant regulations such as the EU’s RoHS
regulations and Batteries Directive, as well as the USA’s EPA
initiative to ‘Reduce, Reuse, Recycle’. Element-U are provided to
customers to support the service Elemental Machines provides,
but they remain the property of Elemental Machines and should
be returned to EM at the end of their life for reuse, recycling or
disposal as appropriate. Elemental Machines relies on customers
to play their role in the process of disposing of Element-U’s
correctly, to help Elemental Machines in protecting the environ-
ment.
The Element-U is marked with this symbol, the EU’s
‘wheeled bin’ symbol, to identify it as Electrical or
Electronic Equipment that the EU requires not to be
added to unsorted municipal waste when it has
reached the end of its life. The correct disposal is:
AA lithium batteries that have reached the end of their life
should be removed from the Element-U, kept separate from
unsorted municipal waste and disposed of according to local
regulations (EU Non-hazardous Waste code: 16 06 04)
Element-U’s that have reached the end of their life should have
their batteries removed for disposal as above and then returned
to Elemental Machines (EU Non-hazardous Waste code 16 02 14)
When batteries need to be removed or replaced, remove the
battery cover on the back of the device and remove the two AA
batteries; these can be replaced with new AA lithium batteries

any questions please contact [email protected].
Prior to Receiving the Element-U
If this is your first time setting up the Elemental Machines system,
you will receive an email for your dashboard account verification.
Save this email for when the devices arrive.
When devices are shipped they will be added to your Elemental
Machines Insights Dashboard™ with default names. When you first
log in you will see all of your devices with a 'disconnected' status.
Install Element-U
Be sure to read and comply with the safety information at the
beginning of this manual concerning operating environment.
Element-U can be placed at an any location on a mains power
cord, but should be installed as close to the front/side of the
equipment as possible to ensure optimal communication with a
Gateway.
The Element-U provides two methods of attaching the device to a
mains cord:
Positioning Element-U
This Element-U needs to be within range of an Elemental
Gateway. The range is usually up to 30 meters, but can depend on
the layout and concentration of equipment in your lab. Signal
strength for an individual Element can be acquired via the
Elemental Machines Insights Dashboard™. Navigate to the device
in question and the signal icon will have 1-4 bars of strength. More
bars indicate a better signal using a low power 2.4GHz wireless
communication protocol. The connection should be sufficient as
long as there are at least 2 bars.
Gateway Setup
This Element-U communicates wirelessly to an Elemental Gateway,
which should be set up prior to connecting Element-U. Depending
on your location and application, your Gateway type may vary. If
you have a tablet Gateway, brief setup instructions are given in the
appendix below. If you have a Gateway Model GW2, please follow
the setup instructions in your Gateway, GW2 User Manual.
Clamp Method - For Most Power Cords (5-12mm)
The provided clamp and thumbscrews can be used to easily attach
the Element-U to a mains power cord.
1: Unscrew the thumbscrews ensuring the cable clamp is still
attached, but has enough room to slide the cable in place.
Some larger cables may require removing the clamp completely
and then screwing the clamp back on.
2: Lay the cord flat in the groove with the sensors.
3: Gently holding the clamp in place, rotate the thumbscrews from
the opposite face of the Element-U.
4: Tighten the thumbscrews until they are finger-tight only. The
Element-U should not move or slide on the cord with the clamp
in place. Do not use tools to tighten the screws further.
Cable Tie Method – For Larger Power Cords (>12mm)
For power cords larger than 12mm in diameter, cable ties should
be used instead of the provided clamp.
1: Completely unscrew the two thumbscrews and set the cable
clamp & thumbscrews aside. They are not required for this
installation.
2: Use the 3 provided cable ties through the Element-U. Do not
close the cable ties yet.
3: Lay the cord flat in the groove with the sensors, sitting between

Positioning the Tablet Gateway
Tablet Gateways collect data from the Elements, collating it and
transmitting it across the internet to Elemental Machines’ Cloud.
The tablet Gateways’ default is to transmit by Wi-Fi; for added
reliability they fall back to Cellular connection when Wi-Fi connec-
tion drops out. There is a danger of data delay or even loss if all
connection is lost, so tablet Gateways should be positioned where
they are getting good Wi-Fi and Cellular connection.
The strength of the Wi-Fi and Cellular connection are displayed by
the Wi-Fi icon using Cellular bar icons. These icons are displayed
5: There is no way for outside users to get into the user's network
6: We do not listen to any ports; this is the case even if the user
opens ports 80, 123, or 443 for receipt
Tablet Gateways opens connections through port 80, 123, and 443
of a customer's firewall, opening only outbound connections.
Elemental Gateways require the following outbound TCP connec-
tions to be open on your firewall for the system to work:
• *.elementalmachines.io:443, TCP – for sending data to the
dashboard
• s3.amazonaws.com:[80|443], TCP – various files
• *.awmdm.com:443, TCP – device management

Elemental Machines Sensory Network Secu-
rity Overview
The Elemental Machines Sensory Network is designed to operate
securely on our customers’ networks. The system includes
Elements, wireless devices that monitor critical equipment and/or
the ambient environment, Elemental Gateways, which gather data
from Elements, and the Elemental Machines Insights Dashboard™.
Local Communication
Individual Elements communicate to a local Gateway via a low
power 2.4GHz wireless communication protocol, typically 8 dBm or
lower power. Only whitelisted devices can connect with the
Gateway; the whitelist is populated prior to shipping and adjusted
with any subsequent additions to the network.
Communication through Customer Wi-Fi:
The system uses established communication and security
standards to protect data transmitted between Gateways and the
Elemental Machines Insights Dashboard™ .
• TLS, the web standard for protecting sensitive data including
usernames, passwords, credit card, and banking information.
• Asymmetric Cryptography is used to encrypt the data transmit-
ted. The keys for this symmetric encryption are generated
uniquely for each connection and are based on a shared secret
negotiated at the start of the session.
The Elemental Machines’ Sensory Network external communica-
tion is designed to work even in the strictest environments. The
communication uses an adaptive transport mechanism that is
designed to work well when confronted with proxy authorities,
firewalls, and antivirus software.
No inbound ports need to be opened. Security vulnerability using
the above configuration is prevented as follows:
1: Internet Communication over port 80, 123, and 443
2: Device must be able to transmit outward to the Internet on 443
3: Clients do not open inbound ports
4: There is no need to open the firewall to receive on port 80, 123,
or 443
on the tablet Gateway to the left of the battery percentage.
• 4 or more bars for both Wi-Fi and cell indicate good
connectivity
• 2 bars for both Wi-Fi and cell runs an increased risk of some
data delay or loss
• <2 bars for cell or Wi-Fi carry a danger of significant data delay
or loss
