6.2 Output side attaching external capacitor
¡
Depending on the capacitance of the external capacitor, reso-
nance may occur due to ESR, ESL, and wiring inductance, so
please be careful of ripple increase.
¡
If the external capacitor is too large, the power supply might not
start up.

6.3 Others
¡
This power supply is the rugged PCB type. Do not drop conduc-
tive objects in the power supply.
¡
At light load, there remains high voltage inside the power supply
for a few minutes after power OFF.
Be careful of electric shock during maintenance.
¡
This power supply is manufactured by SMD technology. The
stress to PCB like twisting or bending causes the defect of the
unit, so handle the unit with care.
-
Please tighten screws in all mounting holes.

-
Install it so that PCB may become parallel to the clamp face.
-
Avoid dropping unit.
¡
While turning on the electricity, and for a while after turning off,
please don’t touch the inside of power supply because some com-
ponents could be hot.
