Mounting Method Caution
⑴ This Power supply unit is a forced air-cooling system with a
built-in fan.
⑵ This power supply has ventilating holes on the front and back
panels.
Keep these areas freely more than 100mm from front side
and more than 50mm from rear side.
⑶ Please note that ventilation will be worsened in a dusty environ-
ment.
⑷ Built-in fan is limited life part, which require periodic replace-
ment. (Replacement will be charge).
⑸ The ambient temperature of this power supply is less than
50mm from the center of a front side.
⑹ The maximum allowable penetration of mounting screw is 6mm.
⑺ Recommended torque for mounting screw (M4) is 1.27N・m.

3. Mounting Directions
Output Derating
Mounting directions are as follows.
Standard mounting method is (A). Methods (B), (C) and (D) are
also possible. Mounting methods besides (A), (B), (C) and (D)
(example: (E) and (F)) are inhibit.

* Adjustable output voltage within 20% (3Vmodel : 30% )
of output (less than 1V of PV voltage) is proportional to PV
voltage and has a linear characteristic. However, for output
voltage within 10% of output (about less than 0.5V of PV
voltage), output will go into intermittent mode and ripple
voltage becomes large, also irregular sound is release from
the power supply. However, it is not damage. There will
also be cases of the power supply shutting down triggered
by under voltage lock out protection function. With output
shutting down, low output detection function (PF) triggers
the PF signal and set it to "H", and also output LED is
switch off . Under voltage lock out protection mode, switch
off input for a few minutes and then switch on input again
for recovery. Recovery from under voltage lock out is also
possible by turning remote ON/OFF control signal OFF
and ON. Under voltage detection value uses an automatic
tracking mode, which follows the output voltage and
constantly correspond to the 70% -80% of output voltage
with a protection function mode. Base on the explanation
above, we will kindly exclude the usage of adjustable
output voltage within 20% of the output voltage from the
product warranty. For application that requires variable
output voltage within 20% of output voltage, please
kindly consider the above contents prior to operation. For
application that requires output voltage below 20%, due
to diff erent type of application for the user's system, there
might be a situation ( behavior ) different from the one
mentioned above. Therefore please check with the user
system.
Output Peak Current
For model with output peak current, please meet the
following condition.Reduce peak current value according
to output derating as section 4-1.
The output is shut down by protection circuit when rated
current and continuous peak output time (τ) exceeds
rated value during usage.
When protection circuit is activated, input is temporarily
cut off for a few minutes and then power is re-input or
remote ON/OFF control signal should be input for recovery
of the output.
