USB Maintenance Interface Connected to a PC

Description

Use the USB maintenance interface connected to a PC running EcoStruxure Power Commission software to carry out the complete range of checks, tests and adjustments on the MicroLogic trip unit.

There are two possible ways to connect the PC to the USB maintenance interface:

  • Using the USB port

  • Using the Bluetooth/Modbus option

NOTE: The USB maintenance interface cannot be used with the MicroLogic 2.3 trip unit installed in a ComPact NSX400K circuit breaker.
