FG should be connected to the earth terminal of the apparatus.
If not, the conducted noise and output noise will increase.

• The output load line and input line shall be separated and
twisted to improve noise sen-sitivity.
• Use all lines as thick and short as possible to make lower
impedance.
• Noise can be eliminated by attaching a capacitor to the load
terminals.
• For safety and EMI considerations, connect FG to ground
terminal of equipment where power supply is mounted on.
• Recommended screw torque is 0.49N
･
m (5kgf
･
cm).
• Select the wire materials to adapt the connector as follows.
INPUT : AWG#22-#18
OUTPUT : AWG#22-#18
5. Wiring Method
Refer to the following fuse rating and use high-braking capac-
ity fuse when selecting the external fuses that are to be used
on input line. Surge current flows when line turns on. There-
fore use slow-blow fuse or time-lug fuse. Do not use fast-blow
fuse. Fuse rating is specified 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.
CME150 : 5.0A
CME240P : 6.3A
6. External Fuse Rating
Before concluding that this product is at fault, make the follow-
ing checks.
• Check if the rated input voltage is connected.
• Check if the wiring of input and output is correct.
• Check if the wire material is not too thin.
• Check if the output voltage control (V.ADJ) is properly ad-
justed.
• Check if the output current and output wattage is not over
specification.
• Audible noise can be heard during
dynamic-load
operation.
• Audible noise can be heard when input voltage waveform is
not sinusoidal wave.
