Configuration 5: Interface from front panel (Electronic trip unit and HMI030 Unit)
With XT2 and XT4 circuit-breakers, equipped with electronical trip unit Ekip LSI, Ekip LSIG, Ekip
E-LSIG or Ekip M-LRIU, in addiction with the interface unit HMI030, it’s possible to visualize directly
on the panel door the mainly electrical magnitude values and the last trip information.
The necessary accessories, useful to permit the lecture directly from the front of the switchboard are:
Q interface device HMI030;
Q kit of 24V DC auxiliary voltage for electronic trip unit.
Four cables come out of the Ekip E-LSIG, Ekip LSI, Ekip LSIG or Ekip M-LRIU trip unit, two of which
are needed for the auxiliary power supply and two for connection to the HMI030 on Internal Bus.
This configuration makes it possible to read the measurements and alarms from the electronic trip
unit by means of the HMI030 accessory positioned on the front of the panel.
For further details on cabling the various different devices, refer to the Electric Diagram Chapter.
