DOCA0101EN-04 07/2020

SAFETY NOTICE

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, CSA Z462, NOM 029-STPS or local equivalent.

This equipment must only be installed and serviced by qualified electrical personnel.

Turn off all power supplying this equipment before working on or inside this equipment.

Always use a properly rated voltage sensing device to confirm power is off.

Replace all devices, doors, and covers before turning on power to this equipment.

Beware of potential hazards, and carefully inspect the work area for tools and objects that may have been left inside the equipment.

Failure to follow these instructions will result in death or serious injury.

CYBERSECURITY SAFETY NOTICE

WARNING

POTENTIAL COMPROMISE OF SYSTEM AVAILABILITY, INTEGRITY, AND CONFIDENTIALITY

Change default passwords at first use to help prevent unauthorized access to device settings, controls, and information.

Disable unused ports/services and default accounts to help minimize pathways for malicious attackers.

Place networked devices behind multiple layers of cyber defenses (such as firewalls, network segmentation, and network intrusion detection and protection).

Use cybersecurity best practices (for example, least privilege, separation of duties) to help prevent unauthorized exposure, loss, modification of data and logs, or interruption of services.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

MasterPact MTZ2/MTZ3 Description

NFC Communication Zone

The NFC communication zone is used to establish an NFC connection between a smartphone running the EcoStruxure PowerDevice appandtheMicroLogic Xcontrolunit.Whentheconnectionisestablished,the circuit breaker operating data is automatically uploaded to the smartphone.

Bluetooth Activation Button and LED

The Bluetooth activation button is used to establish a Bluetooth low energy connection between a smartphone running the EcoStruxure Power Device app and the MicroLogic X control unit. When the connection is established, the circuit breaker can be monitored and controlled from the smartphone.

When the Bluetooth LED is blinking, it indicates that the MicroLogic X control unit is in communication with a Bluetooth device.

Test Button

The test button is used to test the ground-fault protection for MicroLogic 6.0 X and the earth-leakage protection for MicroLogic 7.0 X.

Overload and Trip Cause LEDs

The indications of the four trip cause LEDs depend on the type of MicroLogic X control unit.

LEDs	Description
	 MicroLogic 2.0 X, 5.0 X, 6.0 X, 7.0 X: Overload pre-alarm, the load exceeds 90%
	and is lower than 105% of the Ir setting of the long-time protection.

MicroLogic 2.0 X, 5.0 X, 6.0 X, 7.0 X: Overload alarm, the load exceeds 105% of the Ir setting of the long-time protection.

MicroLogic 2.0 X, 5.0 X, 6.0 X, 7.0 X: Trip due to long-time protection.

MicroLogic 2.0 X: Trip due to instantaneous protection.

MicroLogic 5.0 X, 6.0 X, 7.0 X: Trip due to short-time protection or instantaneous protection.

MicroLogic 2.0 X, 5.0 X: Not applicable.

MicroLogic 6.0 X: Trip due to ground-fault protection.

MicroLogic 7.0 X: Trip due to earth-leakage protection.

MicroLogic 2.0 X, 5.0 X, 6.0 X, 7.0 X: Trip due to optional protections.

MicroLogic 2.0 X,5.0 X,6.0 X,7.0 X:MicroLogiccontrolunitinvalidresultdetected during self test.

NOTE: If the MicroLogic X control unit is not powered, the trip cause LEDs go off after 4 hours. After this period, press the Test/Reset button to light them again.

DOCA0101EN-04 07/2020

MasterPact MTZ2/MTZ3 Description

Test/Reset Button

The Test/Reset button performs the following functions:

TestoftheinternalbatteryorcheckLEDfunctionality:pressandholdtheTest/Resetbuttonforlessthan 3 seconds, the four trip cause LEDs switch off for one second. One of the following results:

The four trip cause LEDs switch on for two seconds: the battery is OK.

The four trip cause LEDs flash sequentially for two seconds: the battery is near the end of its life. Replace the battery.

The four trip cause LEDs do not light: replace the battery.

NOTE: This test must be carried out immediately after the replacement of the internal battery to check the correct functioning of the new battery. It can then be carried out at any time in the life of the internal battery.

Reset of the latched events: press and hold the Test/Reset button for more than 3 seconds to reset the latched events. The trip cause LEDs and the service LED switch off.

Mini USB Port

Remove the rubber cover of the mini USB port to connect the following devices:

A Mobile Power Pack to supply power to the MicroLogic X control unit.

A smartphone running the EcoStruxure Power Device app through USB OTG connection.

A PC running EcoStruxure Power Commission software.

NOTE: The MicroLogic X control unit does not support USB keys. Even if a USB key is connected using an adapter, data is not transferred.

QR Code

When the QR code on the front face of a MicroLogic X control unit is scanned with a smartphone running a QR code reader and connected to the Internet, the Go2SE landing page is displayed (see page 29). The landing page displays some information about the device and a list of menus.

Control Unit Identification Number

The identification number is made up as follows:

The serial number of the MicroLogic X control unit in the format FFFFFFYYWWDLXXXX

The commercial reference of the control unit in the format LV8•••••

Use the identification number to register your MicroLogic X control unit through mySchneider app, the customer care mobile application.

Registering your MicroLogic X control unit enables you to keep your records up to date and enables traceability.

Control Unit Type

This code indicates the type of MicroLogic control unit:

The number (for example, 6.0) defines the types of protection provided by the control unit.

The letter (X) identifies the range of the control unit.

Internal Battery

The internal battery powers the trip cause LEDs and the main diagnostic functions in the absence of any other power supply.

VPS Voltage Power Supply Module

The VPS module provides an internal voltage supply to the MicroLogic X control unit.

The VPS module is optional for MicroLogic 2.0 X, 5.0 X, and 6.0 X. It is installed as standard on MicroLogic 7.0 X.

Sensor Plug

The protection ranges depend on the rated current In, defined by the sensor plug present below the MicroLogic X control unit.
