Schematics With ComPact NSX Circuit Breakers

General Description

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

Connection of the IFM interface to the MicroLogic trip unit.
Connection of the IFM interface to the BSCM module.
Connection of the IFM interface to the BSCM module or the MicroLogic trip unit.

For more information, refer to the ULP System User Guide.

ULP Connection

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

All the connection configurations require the NSX cord. The insulated NSX cord is mandatory for system voltages greater than 480 Vac.

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

A NSX cord or RJ45 ULP cord

B ULP line termination

Connection of the IFM Interface to the MicroLogic Trip Unit

A IFM Modbus-SL interface for one circuit breaker

B NSX cord

C MicroLogic trip unit

Connection of the IFM Interface to the BSCM Module

A IFM Modbus-SL interface for one circuit breaker

B NSX cord

C BSCM breaker status control module

Connection of the IFM Interface to the BSCM Module and to the MicroLogic Trip Unit

A IFM Modbus-SL interface for one circuit breaker

B NSX cord

C BSCM breaker status control module

D MicroLogic trip unit

Connection of the IFM Interface to a Circuit Breaker for System Voltage Greater Than 480 Vac

A IFM Modbus-SL interface for one circuit breaker

B RJ45 ULP cable

C Insulated ULP module for system voltage greater than 480 Vac

D Insulated ULP cord for system voltage greater than 480 Vac

E Connector for ComPact NSX internal connection
