(4)
For Class II end equipment,
(Functional Earth) can’t be connected, All mounting holes are should be connected to the Chassis by
insulated spacer. This power supply is also suitable for Class II application, however please countermeasure EMC performance
before using.

8. Wiring Method
(1)
The output load line, input line and signal 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
with the terminal of protective earth of equipment firmly.
(5)
Select the wire materials to the JST connector as follows.
Input wire
: AWG#18
~
AWG#16
9. The life expectancy
The life of the power supply depends on the life of the built-in aluminum electrolytic capacitor. The life is described in reliability data.
The life of the aluminum electrolytic capacitor varies depending on the method of mounting the power supply, the load current, and the
ambient temperature. Please refer to
“
Electrolytic Capacitor Lifetime”.
Please do not use the product which passed over the life expectancy. There is a risk of unexpected output shutdown
and specifications may not be satisfied.
Please contact us for maintenance or exchange the product which passed over the life expectancy.
10. 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.

11. Before concluding that the unit is at fault
(1)
Check if the rated input voltage is connected.
(2)
Check if the wiring of input and output is correct.
(3)
Check if the wire thickness is enough.
(4)
Check if the output current and output wattage dose not over specification.
(5)
Check if the output voltage adjust trimmer (VR51) is properly adjusted. OVP might be triggered and output is shut down.
(6)
Check if the Remote ON/OFF control circuit is connected correctly.
(7)
Audible noise can be heard when input voltage waveform is not sinusoidal wave.
(8)
Audible noise can be heard during Dynamic-Load operation.
(9)
Ensure that a large capacitor is not connected across the output terminals. Please use within maximum capacitance shown below.
