If you exceed the ratedamount of capacitor, output for power supply may be stopped orpower supply may be unsteable.6.4 Others!High voltage exist in the power supply for a few minutes afterinput voltage is stopped. Please pay attention to this during themaintence.!Notes for mounting1All Mounting holes should be tight and secured.2 Power supply should be mounted parallel to the mounting surface.3Avoid applying mechanical stress or shock to the power supply.!When power supply is energized or immidately after power supplystops working, power supply is still very hot, so please handle itwith care.!Notes for wiring1Please use thick wires that have enough current capacity.2 Avoid contact with mounted parts.1MOPPprimary secondary1MOPPSafety GNDFig.6.10 Medical Isolation Grade6.3 External capacitor on the output side!When the load currnet changes rapidly, for output stability improvement,we recommend that you connect the capacitor to theoutput terminal.GHA-30
