JFS SERIES INSTRUCTION MANUAL
Lambda JFS Series Safety and Installation Instructions for Lambda Model JFS0750 To comply with published safety standards; the following instructions must be used in conjunction with the Lambda JFS Series: For earth fault protection, the unit must be protected in the final installation by suitable overcurrent protection means. If protection relies upon building wiring, the end product installation must ensure that the necessary protection is provided. The internal fuse F101 may only be replaced with a Littelfuse type 324015 rated at 15A, 250VAC. The internal fuse F102 may only be replaced with Littelfuse type 324020 rated at 20A, 250VAC. The power supply is intended for use as a component of other equipment. When installing the power supply, the relevant safety standards (EN60950, IEC950, UL1950 or CSA-22.2-950) must be complied with. In particular, creepage and clearance distances and distances through insulation between primary and earth or primary and secondary must be maintained. The power supply output is SELV in accordance with requirements IEC-950. The output available has power greater than 240VA. The CE mark on the product is applied to show conformance with the requirements outlined in the European Union's Low Voltage Directive [72/23/EEC] as amended by the CE Mark Directive [93/68/EEC]. The maximum ambient temperature of the operating environment must not exceed 50C at 750W, 60C at 562W or 70C at 375W.

JFS SERIES INSTRUCTION MANUAL
Sicherheits und Installationsanleitung fur Lambda Modell JFS0750 Die folgende Sicherheitshinweise mussen bei der Verwendung der Netzteile beachtet werden: Gegen Isolationsfehler zum Schutzleiter mu in der Endanwendung eine angemessene Absicherung vorgenommen werden. Falls die Absicherung durch die Gebaudeinstallation erfolgt, mu beim Einbau in das Endgerat entsprechend darauf hingewiesen werden. Die interne Sicherung F101 darf nur gegen den gleichen Typ mit gleichen Werten ausgetauscht werden. Es ist die Sicherung Littelfuse Typ 324015 mit 15A und 250VAC zu verwenden. Die interne Sicherung F102 darf nur gegen den gleichen Typ mit gleichen Werten ausgetauscht werden. Es ist die Sicherung Littelfuse Typ 324020 mit 20A und 250VAC zu verwenden. Das Netzteil ist nur als Baugruppe zum Einbau in Endgerate vorgesehen und nicht zur eigenstandigen Verwendung. Beim Einbau in Endgerate sind die entsprechenden Sicherheitsbestimmungen (z. B. EN 60950, IEC-950, UL-1950, CSA 22.2-950) zu beachten. Im Speziellen ist auf das Einhalten ausreichender Kriech- und Luftstrecken sowie Isolationsabstaenden zwischen dem Primaer- und Sekundaerkreis sowie zum Schutzleiter zu achten. Das Netzteil liefert eine SELV-Spannung in Uebereinstimmung mit IEC-950. Die verfuegbare Ausgangsleistung ist groeer als 240VA. Das CE-Konformitaetszeichen auf dem Produkt zeigt die Uebereinstimmung mit den Anforderungen der EG-Niederspannungs-Richtlinie [72/23/EWG] und der Ergaenzung [93/68/EWG]. Die maximale Arbeitsumgebungstemperatur darf 50C bei 750W, 60C bei 562W und 70C bei 375W nicht ueberschreiten. Die Sicherung mu im L-Leiter (Phase) eingefuegt werden.
