Schematics with ComPacT NSX Circuit Breakers

General Description

Depending on the configuration of the ComPacT NSX circuit breaker, connect the IFE communication interface to the circuit breaker using one of the following configurations:

Connection of the IFE communication interface to the MicroLogic 5, 6 or 7 trip unit
Connection of the IFE communication interface to the BSCM Modbus SL/ULP module
Connection of the IFE communication interface to the BSCM Modbus SL/ULP module and to the MicroLogic 5, 6 or 7 trip unit

For more information, refer to DOCA0093•• ULP System User Guide.

ULP Connection

All connection configurations require the NSX cord or the insulated NSX cord.

DANGER
hazard of electric shock, explosion or arc flash It is forbidden to use the NSX cords LV434200, LV434201, or LV434202 if the system voltage is greater than 480 Vac or 480 Vdc. It is mandatory to use the insulated NSX cord LV434204 if the system voltage is greater than 480 Vac or 480 Vdc, and less than or equal to 690 Vac or 690 Vdc, Failure to follow these instructions will result in death or serious injury.

DANGER

hazard of electric shock, explosion or arc flash

It is forbidden to use the NSX cords LV434200, LV434201, or LV434202 if the system voltage is greater than 480 Vac or 480 Vdc.
It is mandatory to use the insulated NSX cord LV434204 if the system voltage is greater than 480 Vac or 480 Vdc, and less than or equal to 690 Vac or 690 Vdc,

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

NOTICE
HAZARD OF EQUIPMENT DAMAGE Never connect an Ethernet device to a RJ45 ULP port. The RJ45 ULP ports of IFE interface are for ULP modules only. Any other use can damage the IFE interface or the device connected to the IFE interface. To check if a ULP module is compatible with the RJ45 ULP ports of IFE interface, refer to DOCA0093•• ULP System User Guide. Failure to follow these instructions can result in equipment damage.

NOTICE

HAZARD OF EQUIPMENT DAMAGE

Never connect an Ethernet device to a RJ45 ULP port.
The RJ45 ULP ports of IFE interface are for ULP modules only.
Any other use can damage the IFE interface or the device connected to the IFE interface.
To check if a ULP module is compatible with the RJ45 ULP ports of IFE interface, refer to DOCA0093•• ULP System User Guide.

Failure to follow these instructions can result in equipment damage.

When the second RJ45 ULP port is not used, it must be closed with an ULP line termination.
