Sikker og pålidelig opladning af elektriske køretøjer, er direkte relateret til den elektriske sikkerhed i bygningsinstallation, og naturligvis i selv ladestanderen. RCMB104 Module is for anvendelse i marker med måletransformer type W15BS og et RCD type a (tidligere kaldet et HPFI), som skal være tilstede i ladestanderen. Dette til fejlstrømsbeskyttelse af AC-
Reststrømsovervågning udføres ved hjælp af eksternt tilsluttede målevandstransformatorer. Hendes er r.m.s. værdien afstilkes af den DC-komponent, der er posterede i reststrømmen, og AC-komponenten, der er under cut-off frekvensen..
Udgangssignal angiver, om grænserne for IΔn = DC ≥ 6 Ma og/eller IΔn = RMS ≥ 30 ma overskrides. Udstyrstesten indledes via et eksternt styresystem (ladestyring). Efter start af selvtesten via den digitale indgang "test", genererer udstyret en teststrøm. Niveauet af teststrømmen er udformet således, på tærskelværdien overskrides, når de fungerer korrekt, og udløser begge alarmrelæer. Baseret på systembetingelserne (reststrømsovervågning, Lastadskiller), registrerer laderegulatoren om den forventede afbrydelse finder sted. Efter en vellykket afprøvning, udføres en offsetmåling.
Før hver opladningsproces er det nødvendigt, på overvågningsudstyret gennemfører en selvtest og en offset måling. Kontrollen fokuserer på sikkerhedsrelevante fejlstrømsovervågning. Funktionen øger sikkerhed ved opladningsprocessen, og forhindrer langvarig driftudfald.
