Operation is being performed in
excess of the rated output current of
the product.
Change to a product with less load or larger output capacity.
However, the Power Supply can be used as long as the operating
conditions specified in Peak current (P.14) are satisfied.
Overload protection is activated for
the product, and the output voltage
drops.
Make sure the output line and the load are not short-circuited.
If there is no short-circuiting, change to a product with less load or
larger output capacity.
The product may have failed, or the
overvoltage protection may have
been activated for the product.
To check for overvoltage protection, turn the input power OFF, and
then turn it ON again after 3 minutes or more has elapsed. If no
output voltage is output, the product may have failed. Replace the
product.
No input voltage is being supplied.
Make sure the circuit breaker connected to the input side has not
tripped, or the fuse connected to the input side has not blown.
Turn ON the circuit breaker or replace the fuse. Turn the input
power ON again, and if no output voltage is output, the product
may have failed. Replace the product.
