Wiring Method - TDK-Lambda CUT75 Mode D'emploi

▥ ▥ ▥ ▥ Condition to meet Isolation & Withstand Voltage standard.
Keep 4mm space from the surfaces and sides of PCB. Especially, 8mm space is necessary from the solder surface.
If the space is not enough, the specification of isolation and withstand will not be satisfied.
Keep enough space in the power supply surroundings and the upper area of components for convection cooling.
(Protective Earth) should be connected to the earth terminal of the equipment. Also the mounting hole are should be connected to the
Chassis by metal spacer. If not, the conducted noise, radiation noise and output noise will increase. Refer to figure below.

6. Wiring Method

(1) The output load line and input line shall be separated each other and twisted individually to improve noise.
(2) Use all lines as thick and short as possible to made lower impedance.
(3) Noise can be reduced by attaching a capacitor to the load terminals.
(4) For safety and EMI considerations, connect between
equipment firmly.
7. External Fuse Rating
Refer to the following fuse rating when selecting the external fuses that are to be used on input line. Surge current flows when line turns on.
Have to use slow-blow or time-lag type fuse, not fast-blow fuse. Fuse rating is considered by in-rush current value at line turn-on. Do not
select the fuse according to input current (RMS.) values under the actual load condition
CUT75: 2.5A
8. Before concluding that the unit is at fault
(1) Check if the rated input voltage is connected.
