Title (EN) CIRCUIT ARRANGEMENT FOR SWITCHING INVERTER APPLIANCES
(FR) ENSEMBLE CIRCUIT SERVANT À COMMUTER DES APPAREILS ONDULEURS
(DE) SCHALTUNGSANORDNUNG ZUM SCHALTEN VON WECHSELRICHTERGERÄTEN
Abstract:
(EN) The invention relates to a circuit arrangement (1) for secure switching of inverter appliances (2) of a facility by means of a common emergency switch (3) connected to a switching signal input (4) of one of the inverter appliances (2), which is configured as the master of the facility and has a switching signal output (5) to which other inverter appliances (2) of the facility, configured as the slaves, are connected by means of switching signal lines (6). The inverter appliances (2) configured as the slaves form a switching chain together with the inverter appliance (2) configured as the master, which is automatically switched when the emergency switch (3) is actuated.
(FR) L'invention concerne un ensemble circuit (1) servant à commuter de manière sûre des appareils onduleurs (2) d'une installation, au moyen d'un commutateur de secours commun (3) qui est raccordé à une entrée de signal de commutation (4) de l'un des appareils onduleurs (2) configuré comme maître de l'installation et présentant une sortie de signal de commutation (5), à laquelle d'autres appareils onduleurs (2) de l'installation configurés comme esclaves sont raccordés par l'intermédiaire de lignes de signaux de commutation (6), les appareils onduleurs (2) formant conjointement avec l'appareil onduleur (2) configuré comme maître une chaîne de commutation qui est commutée automatiquement lors de l'actionnement du commutateur de secours (3).
(DE) Schaltungsanordnung (1) zum sicheren Schalten von Wechselrichtergeräten (2) einer Anlage durch einen gemeinsamen Notschalter (3), der an einem Schaltsignaleingang (4) eines der Wechselrichtergeräte (2) angeschlossen ist, das als Master der Anlage konfiguriert ist und einen Schaltsignalausgang (5) aufweist, an dem andere als Slave konfigurierte Wechselrichtergeräte (2) der Anlage über Schaltsignalleitungen (6) angeschlossen sind, wobei die als Slave konfigurierten Wechselrichtergeräte (2) zusammen mit dem als Master konfigurierten Wechselrichtergerät (2) eine Schaltkette bilden, welche bei Betätigung des Notschalters (3) automatisch geschaltet wird.
