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.

E USB standard connection cable from the USB maintenance interface to the PC

NOTE: If the USB port does not supply enough power to energize the MicroLogic trip unit and the USB maintenance interface, the three test LEDs on the USB maintenance interface start to blink. In such cases, provide energy to the USB maintenance interface from the power supply module supplied with the USB maintenance interface kit.
