Closing the Device

Closing Conditions

To close the device, the following conditions must be met:

Device is open (O).
Closing spring is charged.
The device is ready to close, OK is displayed.

NOTE: An opening order always takes priority over a closing order. The device cannot be closed while an opening order is being received. If OK is crossed-out on the ready-to-close indicator, an order to open is being received (either electrically or mechanically) and must be ended before OK can be displayed.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Do not re-close the device on an electrical fault. First inspect and, if necessary, repair the downstream equipment. Failure to follow these instructions will result in death or serious injury.

Closing the Device

The following tables present the different ways to close the device in the different control modes available.

The device can be closed in the following ways in all control modes:

Closing type	Control mode	Accessories	Closing action
Mechanical	Manual, Auto: Local, or Auto: Remote	–	Press the closing pushbutton on the front of the device. The closing action is possible when the closing conditions are met.
Electrical with BPFE	Manual, Auto: Local, or Auto: Remote	BPFE electrical closing pushbutton XF communicating closing voltage release Isolation module	Press the BPFE electrical closing pushbutton, mounted on the front cover. The closing action takes into account internal closing conditions of the device and the external conditions that are part of the control and monitoring system of the installation.
External pushbutton	Manual, Auto: Local, or Auto: Remote	External pushbutton wired by customer XF standard or communicating closing voltage release Isolation module MCH gear motor	Press the external pushbutton, which is connected to the XF closing voltage release through the customer terminal block.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Do not operate the circuit breaker without confirming that doing so will not create a hazardous situation. Do not allow any person to work on the electrical network without physically validating the successful execution of the local or remote software actions for closing the circuit breaker or switching on the electrical circuit. Failure to follow these instructions will result in death or serious injury.

Closing type	Control mode	Accessories	Closing action
Through IO module	Auto: Local or Auto: Remote	XF communicating closing voltage release Isolation module MCH gear motor ULP port module IO module	Close the circuit breaker by using the predefined application 2 Breaker Operation of the IO module: When the circuit breaker is set to local control mode by the IO module, the command to close is issued from local pushbuttons wired on digital inputs. When the circuit breaker is set to remote control mode by the IO module, the command to close is issued from remote PLC outputs wired on digital inputs. Refer to DOCA0055•• Enerlin'X IO - Input/Output Application Module for One Circuit Breaker - User Guide.
Through FDM121 display	Auto: Local	XF communicating closing voltage release Isolation module MCH gear motor ULP port module IO module	Send a command to close the circuit breaker from FDM121 display connected locally to the circuit breaker through the ULP system. The closing action is password-protected.
Through EcoStruxure Power Commission software	Auto: Local	XF communicating closing voltage release Isolation module MCH gear motor	Send a command to close the circuit breaker from EcoStruxure Power Commission software running on a PC connected locally to the circuit breaker through the mini USB port on the MicroLogic X control unit. The closing action is password-protected. Refer to EcoStruxure Power Commission Online Help.
Through EcoStruxure Power Device app	Auto: Local	XF communicating closing voltage release Isolation module MCH gear motor MasterPacT Operation Assistant Digital Module	Send a command to close the circuit breaker from the EcoStruxure Power Device app with MasterPacT Operation Assistant Digital Module, through Bluetooth wireless communication or USB OTG connection. The closing action is password-protected.
Through Modbus communication	Auto: Remote	XF communicating closing voltage release Isolation module MCH gear motor ULP port module IFE, EIFE, or IFM interface, or IFE server	Send a command to close the circuit breaker through the Modbus communication network. The closing action is password-protected. Refer to DOCA0105•• MasterPacT MTZ Circuit Breakers with MicroLogic X Control Units - Modbus Communication - User Guide. NOTE: EcoStruxure Power Commission software running on a PC connected to the circuit breaker through the communication network can be used to send commands to close.
Through IEC 61850 communication	Auto: Remote	XF communicating closing voltage release Isolation module MCH gear motor ULP port module IFE or EIFE interface IEC 61850 for MasterPacT MTZ Digital Module	Send a command to close the circuit breaker through the IEC 61850 communication network. This closing action is password-protected. Refer to DOCA0162•• MasterPacT MTZ Circuit Breakers with MicroLogic X Control Units - IEC 61850 Communication Guide.
Through IFE/EIFE webpages	Auto: Remote	XF communicating closing voltage release Isolation module MCH gear motor ULP port module IFE or EIFE interface, or IFE server	Send a command to close the circuit breaker from the IFE/EIFE control webpage. The closing action is password-protected. Refer to the relevant document: DOCA0084•• Enerlin'X IFE - Ethernet Switchboard Server - User Guide DOCA0142•• Enerlin'X IFE - Ethernet Interface for One Circuit Breaker - User Guide DOCA0106•• Enerlin'X EIFE - Embedded Ethernet Interface for One MasterPacT MTZ Drawout Circuit Breaker - User Guide

If the device does not close, refer to Troubleshooting.

Inhibiting the Closing Function

The closing function can be inhibited by sending a command through:

The communication network or EcoStruxure Power Commission software
The IO module

NOTE: Using EcoStruxure Power Commission software, you can determine whether the closing inhibition can be controlled using the IO module. For more information, refer to EcoStruxure Power Commission Online Help.

WARNING
RESTRICTED CLOSING INHIBITION Do not use the inhibit closing order to lock the circuit breaker in open position. Failure to follow these instructions can result in death, serious injury, or equipment damage.

The inhibit close order inhibits only the closing orders allowed in Auto control mode. The closing orders issued from the mechanical closing pushbutton or BPFE, or from the pushbutton directly connected to the XF voltage release are not inhibited.
