Connectors for photovoltaic systems - Safety requirements and tests

This European Standard applies to connectors of application Class A according to EN 61730-1 for use in photovoltaic systems with rated voltages up to 1 500 V DC and rated currents up to 125 A per contact. This standard applies to connectors without breaking capacity but might be engaged and disengaged under voltage. NOTE For connectors according to Class B and C of EN 61730 as well as for protection for Class II equipment intended for use between 0 V and 120 V d.c. in photovoltaic-systems this standard may be used as a guide.

Steckverbinder für Photovoltaik-Systeme - Sicherheitsanforderungen und Prüfungen

Diese Norm gilt für Steckverbinder zur Verwendung in Photovoltaik-Anlagen mit Bemessungsspannungen bis 1 500 V DC und Bemessungsströmen bis 125 A je Kontakt nach Anwendungsklasse A der EN 61730-1. Sie gilt für Steckverbinder, die keine Schaltleistung haben, jedoch spannungsführend getrennt und gesteckt werden können. ANMERKUNG Diese Norm kann auch für Steckverbinder der Anwenderklasse B und C der EN 61730 sowie für Steckverbinder der Schutzklasse II im Bereich von 0 bis 120 V DC in Photovoltaik-Anlagen angewandt werden, in diesem Fall dient diese Norm als Leitfaden.

Connecteurs pour systèmes photovoltaïques - Exigences de sécurité et essais

La présente norme s’applique à des connecteurs de la classe d’application A conformes à la EN 61730-1, utilisés dans les systèmes photovoltaïques de tension assignée pouvant atteindre 1 500 V en courant continu et de courant assigné pouvant atteindre 125 A par contact. La présente norme s'applique à des connecteurs sans pouvoir de coupure mais qui peuvent être branchés et débranchés sous tension. NOTE La présente norme peut être utilisée comme guide pour des connecteurs conformes aux classes B et C de la EN 61730 ainsi que pour la protection des équipements de classe II utilisables entre 0 V et 120 V c.c. dans des systèmes photovoltaïques.

Konektoriji za fotonapetostne sisteme - Varnostne zahteve in preskusi

Ta standard se uporablja za konektorje razreda uporabe A v skladu s standardom EN 61730-1 za uporabo v fotonapetostnih sistemih z nazivnimi enosmernimi napetostmi do 1000 V in nazivnimi toki do 125 A na stik. Ta standard se uporablja za konektorje brez zmogljivosti prekinitve, vendar jih je mogoče priključiti in odstraniti pod napetostjo.
