TRICON 4351B Tricon communication module

We strongly recommend the following industry network security best practices, such

as locating control and security systems networks behind firewalls and remote devices to isolate them from business networks.
• Install physical controls that prevent unauthorized access to your industrial control and

security systems, components, peripherals, and networks.
• Place all controllers in a locked cabinet and do not leave them in program mode.
• Scan and isolate all mobile data exchange methods of the network, such as CDS, USB

drives, etc., before use in terminals or nodes connected to these networks.
• Never allow a previously connected laptop to connect to a secure or control network to a network that does not have proper sanitation.
• Minimize network exposure to all control system devices and systems and verify that they can never be accessed from the Internet.
• When remote access is required, use a secure method, such as a virtual private network.

Recognize that the vpn may have vulnerabilities and should be updated to the current version that is most available.

Also, realize that vpn security depends on the connected device.
Schneider Electric continues to recommend that customers always follow the “Safety Precautions”

section of the user documentation provided with the instructions in the instruction manual, which includes the following:
• Ensure that network security features in the Triconex solution are always enabled.
• Always deploy security systems on an isolated network.
• Secure all trstation engineering workstations and do not connect to any other network than a secure network.
• Configure operator station to display alarms whenever the Tricon key is switched in “Program” mode.

Each 1747-BA battery contains 0.23 grams of lithium. As a result, up to two batteries can be

shipped together in the United States. Regulations may vary for shipments to or from other

countries/territories. Store in a cool, dry environment with an ambient temperature of 20-25°C

(68-77°F) and a relative humidity of 40-60%. Monitor the temperature and humidity of the

storage area regularly. Lithium metal batteries and battery packs are classified as Category 9

dangerous goods by the United Nations. As far as the transport of lithium metal batteries and battery

packs is concerned, the United Nations recommendations need to be met in accordance with all relevant regulations.

Do not short circuit, disassemble, damage, heat or burn 1747-BA. Do not stack or mix batteries together.

Do not place batteries on metal objects, metal plates, or ESD materials. In the case of multi-battery applications,

replace all batteries in the new battery at the same time as replacing the old one. Keep 1747-BA away from water, rain, snow, frost, or dew.
