7. Before concluding that the unit is at fault…
Before concluding that the unit is at fault, make the follow-
ing checks.
● Check if the rated input voltage is connected.
● Check if the wiring of input and output is correct.
● Check if the wire size is not too thin.
● Check if the output voltage control (V.ADJ) is properly
adjusted.
● Check if the Remote ON/OFF control connector is not
opened, when use Remote ON/OFF control function.
● Check if the output current and output wattage dose not
exceed specifi cation.
● Audible noise can be heard during Dynamic-Load opera-
tion.
● Audible noise can be heard when input voltage wave-
form is not sinusoidal wave.
● Ensure that a large capacitor is not connected on the
output side. Please use within maximum capacitance
shown below.

8. Range of free warranty
Conditions of usage at the free of charge warranty are as
follows.
● Average operating temperature (ambient temperature of
the power supply unit) is under 40ºC.
● Average load factor is 80% or less.
● Installation method : Standard installation.
However, the maximum rating is within the output
derating.
Following cases are not covered by warranty.
● Improper usage like dropping products, applying shock
and defects from operation exceeding specification of
the units.
● Defects resulting from natural disaster (fi re, fl ood).
● Unauthorized modifications or repair by the buyers
defects not cause by TDK-Lambda .
