If it will be connected to AUX, check the currentwhether it is within the spec.4.2 External Output Capacitors!Depending on the external capacitor, resonance may occur dueto ESR, ESL, and wiring inductance, so please be careful of rippleincrease.!If the external capacitor is too large, the output voltage may notstart up.!Please do not connect the external capacitor during operations.!Please see Table 4.1 for maximum value of external output capacitors.If the external output capacitors exceeds the value shown in Table4.1 please contact us for details.!WRN signal may output at start-up caused by charging current tothe capacitor when the external capacitor is connected.Please contact us for details.Table. 4.1 Maximum value of external output capacitorsModelMaximum value of external outputcapacitors [μF]HCA3500TF-480 to 75,000HCA3500TF-650 to 75,0004.3 External Component (EMI/EMC Filter)!The unit will be able to comply with the class B conducted noiseby adding external EMI fi lter.Recommended EMI fi lterHCA3500TF : TAC-30-683 (COSEL)4.4 Grounding!Ensure that the input FG terminal is connected to safety ground ofthe system.5 Options5.1 Outline of Options*Please contact us for details of specifi cations and lead time.*You can combine multiple options.? -R!The logic of the remote in -R option is reversed from the standardunit.
