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.
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.
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.
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.
