Einsatz können die im Gerät integrierten Schutzfunktionen beeinträchtigt werden. TDK-Lambda ist nicht haftbar für Schäden, die durch Missachtung dieser Sicherheitsvorschriften entstehen können. CAUTION: RFE2500-xy units are not authorized for use as critical component in nuclear control systems, life support systems or equipment for use in hazardous environments without the express written approval of the managing director of TDK- Lambda. - Page 9 Erdungskonzept RFE2500-xy-Netzteile sind Produkte der Schutzklasse I. Um die Gefahr eines Stromschlags zu minimieren, müssen die RFE2500-xy-Netzteile an eine Schutzerde angeschlossen werden. Die Geräte müssen über ein dreiadriges Netzkabel an das Wechselstromnetz angeschlossen werden, wobei der PE-Anschluss fest mit einer elektrischen Masse (Schutzerde) an der Netzsteckdose verbunden sein muss.
- Page 10 Spannungsführende Teile Die Geräteabdeckung darf nicht durch Endanwender geöffnet werden. Interne Modifikationen, sowie Bauteileaustausch ist nur durch TDK-Lambda qualifiziertes Personal erlaubt. Vor Austausch von Bauteilen ist das Netzkabel bzw. die Versorgungsspannung zu trennen. Energieversorgungsanschlüsse sind immer zu trennen, um Personenschäden durch gefährliche Energieinhalte und Spannungen auszuschliessen.

Page 21: Smb Alert
5.1.6 SMB Alert SMBALERT is used to indicate to the HOST about any Faults/Error Conditions. This line must be connected to +3.3V (referenced to Signal RTN) via a 1.5kΩ pull up resistor. This Signal is HIGH to indicate that no fault/error is present. If some fault/error occurs, the signal will go LOW. The Host system must poll multiple supplies after receiving SMBALERT to retrieve fault/warning information. -
Page 22: Pmbus Command Set
PMBus Command Set The interval between two consecutive commands to the power supply should be at least 25ms to ensure proper monitoring functionality. 5.2.1 Read Status This Command is used to read the status of the Power Supply.
