The input line and output load shall be separated and twist-
ed to improve noise sensitivity. Noise can be eliminated by
attaching a capacitor to the load terminals.
Refer to the following fuse rating when selecting the ex-
ternal fuses that are to be used on input line. Do not use
fast-blow fuse. Fuse rating is specified by inrush current
value at line turn-on.
Do not select the fuse according to input current (RMS)
values under the actual load condition.
● Check if the rated input voltage is connected.
● Check if the wiring of input and output are correct.
● Ensure the input and output connectors are firmly in-
● Check if the wiring material is not too thin.
● Check if output current are more than minimum output
● Check if FG terminal is connected to safety ground.
● Ensure that a large capacitor is not connected on the
serted and the pressing of the connector pins are ex-
actly fixed.
