C: 1-F4.5 holes and R2.25 slot hole by 2-M4 screws
D: Embossed tapped and countersunk holes by 2-M4 screws.
5. Wiring Method
The output load line and input line shall be separated and
twisted to improve noise sensitivity.
Use all lines as thick and short as possible to have lower
impedance.
Noise can be eliminated by attaching a capacitor to the
load terminals.
For safety and EMI considerations, connect FG terminal
of input connector and mountable PE to ground terminal
of equipment.
Recommened screw torque is 0.49N.m ( 5kg.cm )
Select the wire materials to adapt to the MOLEX and
J.S.T connector as follows.
INPUT : AWG#22 ~ #18 (
OUTPUT : AWG#22 ~ #18 (
6. 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 is turned on. Use high breaking and slow-blow fuse or
time-lag type 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.

7. Before concluding that the unit is at fault...
Before concluding that the unit is at fault, make the following
checks.
·
Check if the rated input voltage is connected.
·
Check if the wiring of input and output is correct.
Output
·
Check that the wire material is not too thin.
·
Check if the output voltage control ( V.ADJ ) is properly
adjusted.
·
If you use the Remote ON/OFF control function, make
sure the Remote ON/OFF control connector is not opened.
·
Check that the output current and output wattage is not
over specification.
·
Audible noise may be heard during Dynamic-Load oper-
ation.
·
Audible noise may be heard when input voltage waveform
is not sinusoidal wave.
