Schematics With ComPacT NSX Circuit Breakers

Depending on the type of circuit breaker used, the user must connect the IFM communication interface using one of the following configurations:

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

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.

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 The RJ45 ports of IFM communication interface are for ULP modules only. Any other use can damage the IFM communication interface or the device connected to the IFM communication interface. To check if an ULP module is compatible with the RJ45 ports of IFM communication interface, refer to DOCA0093•• ULP System User Guide. Failure to follow these instructions can result in equipment damage.

NOTICE

HAZARD OF EQUIPMENT DAMAGE

The RJ45 ports of IFM communication interface are for ULP modules only.
Any other use can damage the IFM communication interface or the device connected to the IFM communication interface.
To check if an ULP module is compatible with the RJ45 ports of IFM communication interface, refer to DOCA0093•• ULP System User Guide.

Failure to follow these instructions can result in equipment damage.

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

B NSX cord

C MicroLogic 5, 6 or 7 trip unit

A IFM Modbus SL communication interface for one circuit breaker

B NSX cord

C BSCM Modbus SL/ULP module

A IFM Modbus SLL communication interface for one circuit breaker

B NSX cord

C BSCM Modbus SL/ULP module

D MicroLogic 5, 6 or 7 trip unit

DANGER
