Safety Information

Batteries
WARNING: Element-B, Model EB2 is powered by 2 non-rechargeable AAA lithium batteries. These batteries can explode or leak and cause burns if installed backwards, disassembled, charged, or exposed to water, fire, high temperature or rapid warming from extremely cold temperature. For this reason it is important that the main housing of Element-B 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- B periodically sends measurements to a Gateway using a low-power 2.4GHz wireless network. When transmitting, the radio modules inside the Element-B work at a maximum power of 8 dBm ≡ 6.3 mW for Model EB2. 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 commercial environment. If not installed and used in accordance with this User Manual, the Element-B may possibly cause harmful interference to other radio communications. Possible remedies for any such interference include reorienting the receiving antennae or increasing the separation between affected equipment and Element-B. state. Element-B can be provided in normally-open or normallyclosed configurations, and includes a cable to interface with its assigned lab equipment. Data is securely transmitted wirelessly to the Elemental Insights™ Dashboard via the Elemental Machines Gateway, where it is recorded and analyzed for record keeping and alerting.

Protecting the Environment
Element-B’s are designed with consideration for the environment and comply with relevant regulations such as the EU’s and UK’s RoHS regulations and Batteries Directives, as well as the USA’s EPA initiative to ‘Reduce, Reuse, Recycle’. ElementB’s are provided to customers to support the service Elemental Machines provides, but they remain the property of Elemental Machines and should be returned to Elemental Machines 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-B’s correctly, to help Elemental Machines in protecting the environment

Element-B is marked with the international ‘wheeled bin’ symbol, to identify it as Electrical or Electronic Equipment that the EU and UK require not to be added to unsorted municipal waste when it has reached the end of its life.

The correct disposal is:

• AAA Lithium batteries that have reached the end of their life should be removed from the Element-B, kept separate from unsorted municipal waste and disposed of according to local regulations (EU and UK Non-hazardous Waste code: 16 06 05).
• Element-B’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 and UK Non-hazardous Waste code 16 02 14).

When batteries need to be removed or replaced, slide the battery cover that forms most of the base open and remove the two AAA batteries; these can be replaced with new AAA lithium batteries.

Installation Guide

Below are the instructions for installing Element-B. If you have any questions please contact help@elementalmachines.com or your account representative.

Prior to Receiving Element-B

Click on the settings icon

Select WiFi from the list

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 connection 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 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

Appendix 3: Platform Network Summary

Elemental Machines’ platform delivers actionable intel to operators that will help improve operations and speed discovery. Elemental Machines devices are designed to operate securely on our customers’ networks. The entire platform includes:

• Devices called Elements that monitor critical equipment and/or the ambient environment
• Elemental Gateway that gathers data from the non-cloud connected Elements
• Elemental Insights™ dashboard

The full scope of Elemental Machines’ Data Services is shown below:

Local Communication
Wireless sensors (Element-T, Element-A, Element-U Model EU2, and Element-B) communicate individually to a local Elemental Gateway (either an Elemental Tablet Gateway, Elemental Gateway models GW2 or GW3) via a low powered 2.4 GHz wireless communication protocol. These devices do not connect to the corporate network. Each Elemental Gateway will only process data from Elements that are on a pre-defined list that is unique to each installation. This list is created prior to shipping the Gateway and is updated whenever new Elements are added to the network. Element-C, Element-D, and Element-U model EU1 devices do not require an Elemental Gateway and transmit data directly from a piece of equipment to the Elemental Insights™ dashboard via customer Wi-Fi or ethernet.

Communication through Customer Ethernet or Wi-Fi
Elemental Gateway Models GW2/GW3 and Element-C, Element-D, and Element-U Model EU1 will always connect to Ethernet first, if available. If there is no Ethernet then the device will connect to Wi-Fi. The system uses HTTPS to protect data transmitted between Elemental Gateways, Element-C, Element-D, and Element-U Model EU1 devices and necessary API and data ingest endpoints, such as Elemental Insights™. HTTPS is the established communication and security standard for protecting sensitive data transmitted across the web, with applications that include usernames, passwords, credit card, and banking information. Elemental Machines devices use socket connections through port 80, 123, and 443 of a customer’s firewall, opening only outbound connections

Elemental Tablet Gateway requires the following outbound TCP/UDP connections to be open in a customer’s firewall for the system to work

For All Devices , no inbound ports need to be opened. Security vulnerability using the above configuration is prevented as follows:

• Internet communication over Port 80, 123, and 443
• Device must be able to transmit outward to the Internet on 443
• Clients do not open inbound ports
• There is no need to open the firewall to receive on port 80, 123, or 443
• There is no way for outside users to get into the user’s network
• No ports are listened to by Elemental Machines, that is the case even if the user opened ports 80 or 443 for receipt

Elemental Insights™ Dashboard
Communication between the Dashboard and web browsers always uses HTTPS. User access to the Dashboard is restricted to invite-only, requires hardened passwords, and can be revoked by admins at any time. Users are further restricted in what they can access or edit by rolebased account policies

Supplemental Security Information

Elemental Tablet Gateway is based on Android technology and therefore enjoy the security benefits of the Android Development Network and Google. Security benefits, as listed in a security whitepaper from Google about Android, are as follows:

• Strives to prevent security issues from occurring through design reviews, penetration testing, and code audits
• Performs security reviews prior to releasing new versions of Android and Google Play
• Publishes the source code for Android, thus allowing the broader community to uncover flaws and contribute to makingAndroid the most secure mobile platform
• Works hard to minimize the impact of security issues with features like the application sandbox Detects vulnerabilities and security issues by regularly scanning Google Play applications for malware, and removing them from devices if there’s a potential for serious harm to the user devices or data
• Has a rapid response program in place to handle vulnerabilities found in Android by working with hardware and carrier partners to quickly resolve security issues and push security patches.

Elemental Gateway Models GW2, GW3 as well as Element-C, Element-D, and Element-U Model EU1 devices are based on the balenaOS, a thin Linux environment that supports the balenaCloud services and user application containers. Balena offers security by design:

• API access control
• Multiple authentication methods
• Minimized available attack surfaces
• Balena operates its own Virtual Private Cloud (VPC) on Amazon Web Services (AWS) This isolation gives Balena an added layer of security

Elemental Machines Cloud Services

Elemental Machines’ data ingestion and server infrastructure are hosted on Google Cloud Platform, which provides a managed security layer for Google services (PubSub, BigQuery, etc.) and are automatically updated by Google. Other components such as Ruby-on-Rails, Influx, and Postgres databases are maintained to at least the minimum supported version and are updated for any high/critical security vulnerabilities per vendor guidance.
