You can increase output voltage by turning clockwise.
If you need decrease, you can turn it the other way.

Over-Voltage Protection(OVP)
Remote Sensing
・
It detects when the output voltage exceeds by some

reasons, and the output is intercepted at once.

・
When it works once, the over-voltage protection
continues the output interception while the input is
supplied.

Turn it on again after a few minutes after intercepting

Note that the output voltage might be abnormal when
you turn it on again. (In this case, the over voltage
protection works again. )

Note:
We connected with wires between Pin#1 & Pin#2,
Also Pin #3 & Pin#4 as a default settings when we ship
from factory. This setting is for the customers who won't
use remote sensing feature. So, if you need to use this
feature, 1) Please remove the existing wires 2) Use
twisted cable for this feature to use shown as above.
In order to reset this, please disconnect AC input, then
confirm well cooling down the temperature inside the PSU
after several minutes. Then please apply AC input. Also
please confirm the forced air convection would well enough
to meet the air flow condition.
