+
+### FI/RCD-Schutzgruppen (v7.5)
+- Equipment kann einem Schutzgerät (FI/RCD) zugeordnet werden
+- `fk_protection` in `llx_kundenkarte_equipment` speichert die ID des schützenden Equipment
+- Im Editor: Farbige Ränder zeigen Schutzgruppen-Zugehörigkeit
+- `get_protection_devices` API liefert verfügbare Schutzgeräte für Dropdown
+
+### Gebündelte Terminals (v7.5)
+- Multi-Phasen-Abgänge für Drehstrom-Verbraucher (E-Herd, DLE)
+- `bundled_terminals = 'all'` in Connection bedeutet: Alle Terminals belegt
+- Im Editor: Ein Pfeil spannt über alle Terminals des Equipment
+- Label wird zentriert über alle Terminals angezeigt
+- Checkbox "Alle bündeln" nur bei Equipment mit >1 Terminal sichtbar
+
+### Terminal-Konfiguration (v7.5)
+- `terminals_config` JSON im Equipment-Typ definiert Terminal-Positionen
+- Format: `{"terminals":[{"pos":"top"},{"pos":"top"},{"pos":"bottom"}...]}`
+- `getTerminalCount(type, position, fallback)` zählt Terminals pro Position
+- Ermöglicht: 4 TE Breite aber nur 3 Terminals (z.B. Neozed 3F)
+
+### Grid-Layout (5 Zeilen)
+- Zeile 1: Abgang-Labels oben (terminal-label-cell.label-row-top)

 # CHANGELOG MODULE KUNDENKARTE FOR [DOLIBARR ERP CRM](https://www.dolibarr.org)

+## 7.5 (2026-03)
+
+### Neue Features
+
+- **FI/RCD-Schutzgruppen**: Equipment kann Schutzgeraeten zugeordnet werden
+  - Farbliche Markierung der Schutzgruppen im Schaltplan
+  - Dropdown zur Auswahl des Schutzgeraets im Equipment-Dialog
+  - Visuelle Verbindung durch farbige Raender
+
+- **Gebuendelte Terminals**: Multi-Phasen-Abgaenge fuer Drehstrom-Verbraucher
+  - "Alle buendeln" Option fuer E-Herd, Durchlauferhitzer etc.
+  - Ein Abgang belegt alle Terminals des Equipment
+  - Zentrierter Pfeil ueber alle Terminals
+
+- **Terminal-Konfiguration**: Korrekte Terminal-Anzahl aus Typ-Konfiguration
+  - Neozed 3F zeigt 3 statt 4 Terminals (trotz 4 TE Breite)
+  - Neue `getTerminalCount()` Hilfsfunktion
+
+- **Zuletzt bearbeitete Kunden**: Quick-Access auf Search-Screen
+  - Speichert die letzten 5 bearbeiteten Kunden
+  - Schneller Zugriff ohne Suche
+
+- **Medium-Typen aus Datenbank**: Dynamisches Kabeltyp-Dropdown
+  - Kategorisierte Auswahl (NYM, NYY, Datenkabel, etc.)
+  - Querschnitt-Spezifikationen als Unter-Dropdown
+  - Offline-Cache fuer die Auswahl
+
+### Verbesserungen
+
+- Terminal-Labels anklickbar zum direkten Bearbeiten
+- Kontextmenue fuer leere Terminals (Wahl Input/Output)
+- Equipment-Block-Value (B16A) kleiner dargestellt (8px)
+- Terminals direkt am Equipment-Block ausgerichtet
+- Block-Label mit Einheiten und Leerzeichen (40A 30mA)
+
+### Bugfixes
+
+- Abgaenge werden nach Positionswechsel (oben/unten) korrekt angezeigt
+- Bundle-Option nur bei Equipment mit mehr als 1 Terminal sichtbar
+- Login-Fehler durch doppelte Variable-Deklaration behoben
+
+### Datenbank-Aenderungen
+
+- Neue Spalte `bundled_terminals` in `llx_kundenkarte_equipment_connection`
+- Neue Spalten `fk_protection`, `protection_label` in `llx_kundenkarte_equipment`
