Ifthe output exceeds 12.5V, however, please connect the currentlimiting resistor Ra.To calculate a current limiting resistance value, please use thefollowing equation.Ra[W]=Vcc-(1.1+RiX0.005)0.0051.9 Isolation!When you run a Hi-Pot test as receiving inspection, gradually increasethe voltage to start. When you shut down, decrease thevoltage gradually by using a dial. Please avoid a Hi-Pot testerwith a timer because when the timer is turned ON or OFF, it maygenerate a voltage a few times higher than the applied voltage.SW1.10 Signal Output (LED/Warning/Alarm)!Functions of LED indicators and Output of Warning/Alarm areshown below. LED indicators and Output of Warning/Alarm aresignals to check the presence/absence of voltage at the outputterminal of a power supply and to detect warning/fault conditions.The timing of signals might be vary depending on input and loadconditions. Please evaluate thoroughly.Table 1.4 Description of LED indicatorLED indicatorConditionOutput voltageOFFInput power not presentOFFGreen - ONNormal conditionONGreen - BlinkingDC OFF by RC signalOFFAmber - BlinkingWarning condition(refer to Table.1.5)ONAmber - ONFault condition(refer to Table.1.6)OFFTable 1.5 Description of the WarningsWarningOutput of WarningThe WRN signals are“Low”Open collector methodwhen the power supply operatesGood : L levelWRNnormally.The signals turn“High”whenAC input voltage is out ofspecification* or DC outputvoltage is wrong (DC outputis out of voltage adjustmentrange) or fan fan alarm/termal( FETA2500BA,FETA3000BA,FETA3000BC :0 to 0.5V at 3mAFETA7000TFETA7000ST :0 to 0.5V at 10mA)warning is detected.Bad: H level or Open(35Vmax)* FETA7000STThis does not affect product quality.
