Schematics with ComPacT NSX Circuit Breakers

General Description

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

Connection of the IFE interface to the MicroLogic trip unit
Connection of the IFE interface to the BSCM module
Connection of the IFE interface to the BSCM module and to the MicroLogic trip unit

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

ULP Connection

WARNING
HAZARD OF ELECTRIC SHOCK For system voltage greater than 480 Vac: Use the insulated NSX cord LV434204. Do not use NSX cords LV434200, LV434201, and LV434202. Failure to follow these instructions can result in death, serious injury, or 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 the ULP System User Guide in Related Documents. 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 the ULP System User Guide in Related Documents.

Failure to follow these instructions can result in equipment damage.

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