Do not drop conductiveobjects in the power supply.!At light load, there remains high voltage inside the power supplyfor a few minutes after power OFF.So, at maintenance, take care about electric shock.!This power supply is manufactured by SMD technology. Thestress to PCB like twisting or bending causes the defect of theunit, so handle the unit with care.-Tighten all the screws in the screw hole.-Install it so that PCB may become parallel to the clamp face.-Avoid the impact such as drops.!While turning on the electricity, and for a while after turning off,please don’t touch the inside of a power supply because there aresome hot parts in that.!When a mass capacitor is connected with the output terminal (loadside), the output might become the stop or an unstable operation.Please contact us for details when you connect the capacitor.100 50 100 150 200 250 300 350Output power [W]Fig.7.6 Hold-up time by LFP300F-O-TU1Y(Reference data).!Connection methodPower supplyVC(+)VC(-)d=5 - 30mmHarness H-IN-23(sell separately)CN1VC(+) VC(-)External capacitor unit(CR-HUT)Fig.7.7 Connection method? Caution(1) Distance between the external capacitor unit and power supplyunit must be secured more than 5mm.(2) It must be 30mm or less, since the noise is generated from thewire which is connecting the external capacitor unit and powersupply. And, it is necessary to twist the wire as short as possible.(3) It is necessary to use wires which rated voltage is 600V or more.(4) It must be used with the external capacitor unit (CR-HUT).(5) For more information about the external capacitor unit and harness,please refer to Optional Parts.LFP-20
