Functions Accessible Through Bluetooth Wireless Technology

NOTICE
RISK OF UNINTENDED OPERATION The device must only be configured and set by qualified personnel, using the results of the installation protection system study. During commissioning of the installation and following any modification, check that the MicroLogic X configuration and protection function settings are consistent with the results of this study. MicroLogic X protection functions are set by default to the minimum value, except for the long time protection function which is set to the maximum value, by default. Failure to follow these instructions can result in equipment damage.

RISK OF UNINTENDED OPERATION

The device must only be configured and set by qualified personnel, using the results of the installation protection system study.
During commissioning of the installation and following any modification, check that the MicroLogic X configuration and protection function settings are consistent with the results of this study.
MicroLogic X protection functions are set by default to the minimum value, except for the long time protection function which is set to the maximum value, by default.

Failure to follow these instructions can result in equipment damage.

Using Bluetooth Low Energy wireless technology, you can access the MicroLogic X control unit from a smartphone running EcoStruxure Power Device app. This application offers a task-oriented interface with the control unit. Data transferred over Bluetooth wireless technology is encrypted using AES 128-bit encryption algorithm.

NOTE: Bluetooth wireless technology is not available in MicroLogic Active control units.

Prerequisites for Establishing a Bluetooth Connection

To establish a Bluetooth wireless connection with the MicroLogic X control unit, the prerequisites are:

The MicroLogic X control unit must be powered on.
The Bluetooth function must be enabled on the MicroLogic X control unit.
Only one smartphone at a time can connect to a control unit.
You must have a smartphone with EcoStruxure Power Device app installed.
The smartphone must support Bluetooth Low Energy wireless technology (4.0 or above).
You must have access to the MicroLogic X control unit to activate the Bluetooth function by pressing the activation pushbutton, and be physically within range (usually within 20 to 30 meters or yards) for the duration of the connection.
You must enter the 6-digit pairing code randomly generated by the MicroLogic X control unit and displayed on the MicroLogic X HMI .

Any person who meets these conditions, and establishes a connection, has access to functions which can impact your installation.

For detailed procedures on how to establish a Bluetooth connection, refer to MasterPacT MTZ - MicroLogic X Control Unit - User Guide .

General Recommendations for Protecting Access Through Bluetooth Wireless Technology

To protect access to functions accessible through Bluetooth wireless technology, it is recommended to:

Install the MasterPacT MTZ circuit breaker in a locked area so that only authorized personnel can access the MicroLogic X control unit.
Keep that area locked at all times.
Give the key or access code to authorized personnel only.

For further information on protecting access to the MasterPacT MTZ circuit breaker, refer to Implementing a Restricted Access Policy.

Recommendations for Using Bluetooth Wireless Technology

The implementation of the Bluetooth function complies with the NIST Special Publication 800-121 Revision 1. Nevertheless, to protect access to functions accessible through Bluetooth wireless technology, it is recommended to:

Disable the Bluetooth function on the MicroLogic X control unit, and enable it only when you are ready to establish a connection.

For detailed procedures on how to disable the Bluetooth function, refer to MasterPacT MTZ - MicroLogic X Control Unit - User Guide .
Set the Bluetooth function disconnection timer to 5 minutes.
Except when you are starting a Bluetooth connection, the Bluetooth function must not be activated from the activation pushbutton on the front face of the MicroLogic X control unit. The Bluetooth function must remain off when not in use.
Press the Bluetooth pushbutton to end the communication when you have finished.
Pairing must be done only when necessary and in a secure area.
Do not enter a pairing code if unexpectedly prompted for it.
During Bluetooth pairing, keep the smartphone as close as possible to the MicroLogic X control unit.

Recommendations for Using EcoStruxure Power Device App

To restrict access to the MicroLogic X control unit from a smartphone running EcoStruxure Power Device app, it is recommended to use only the official Schneider Electric EcoStruxure Power Device app to connect to the MasterPacT MTZ circuit breaker.

Recommendations for Using Smartphones

To restrict access to the MicroLogic X control unit from a smartphone, it is recommended to:

Make sure that the smartphones that have the EcoStruxure Power Device app are password protected and used for work only.
Harden the smartphones that have the EcoStruxure Power Device app by implementing all of the security features recommended by the smartphone vendor or manufacturer.
Keep antivirus applications for smartphones up to date.
Do not disclose information about the smartphone (telephone number, MAC address) if it is not necessary.
Disconnect the smartphone from the Internet during a Bluetooth connection with the MicroLogic X control unit.
Do not store sensitive information on smartphones.
