Schematics with MasterPact NT/NW and PowerPact P- and R-Frame Circuit Breakers

General Description

Depending on the type of circuit breaker used, the IFM interface must be connected to the circuit breaker by using one of the following configurations:

Connect the IFM interface to a fixed manually-operated PowerPact P- or R-frame circuit breaker with a BCM ULP module.
Connect the IFM interface to a fixed electrically-operated MasterPact NT/NW or PowerPact P- or R-frame circuit breaker with a BCM ULP module.
Connect the IFM interface to a drawout MasterPact NT/NW or PowerPact P- or R-frame circuit breaker with a BCM ULP module and their respective IO module.

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

ULP Connection

NOTICE
HAZARD OF EQUIPMENT DAMAGE Never connect a Modbus-SL device to an RJ45 ULP port. The RJ45 ULP 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 ULP ports of IFM interface, refer to the ULP System User Guide. Failure to follow these instructions can result in equipment damage.

NOTICE

HAZARD OF EQUIPMENT DAMAGE

Never connect a Modbus-SL device to an RJ45 ULP port.
The RJ45 ULP 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 ULP 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 circuit breaker BCM ULP cord. The insulated NSX cord is mandatory for system voltages greater than 480 Vac.

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

A Circuit breaker BCM ULP cord or RJ45 ULP cord

B ULP line termination
