-
To increase the output voltage, turn a built-in potentiometer
clockwise.
-
To decrease the output voltage, turn it counterclockwise.
-
Please take care when you adjust output voltage by potentiometer,
because there is possibility of electric shock and the breakdown as
contacting to other internal circuit by electrically conductive tool.
5.2 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.
So, at maintenance, take care about electric shock.
¡
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.
-
Tighten all the screws in the screw hole.
-
Install it so that PCB may become parallel to the clamp face.
-
Avoid the impact such as drops.
¡
While turning on the electricity, and for a while after turning off,
please don’t touch the inside of a power supply because there are
some hot parts in that.
