MPPT RS 450/100 auxiliary input configuration

Hi everyone,

today I finished the installation of my Victron MPPT RS 450/100. To monitor the DC fuses i have installed an ethernet cable between the auxiliary contact of the fuses to the auxiliary contact of the MPPT RS 450/100. Now my plan was to configure AUX1 and AUX2 in Victron Connect but there was no option to do that.
Am I missing something?

Best regards
Thomas
