order to reduce the risk of current flowing through
important organs of the body. Keep your left hand off from
the product and operate with your right hand.
Do not touch the wiring or load connected to the
output terminal or output terminal during operation or
immediately after output stop.
Very high voltage is applied to the terminals during normal
operation and trial operation. Touching it will result in
electric shock. In addition, since a capacitor is connected
to the terminal, high voltage remains on the terminal even
immediately after stopping the output. To avoid electric
shock, do not touch the terminals.
Turn off the power when touching the terminal.
Before touching the terminals of the product, turn off the
power and check that the power has actually turned off.
There is a capacitor at the terminal, and it is particularly
dangerous to touch it immediately after turning off the
power supply. Be careful of the electric charge of these
capacitors and connect it to earth to discharge it
completely. Remove input line (AC line) during work.

directly.
There is a danger of condensation, leakage current and
burnout.
Do not install the product in places around corrosive
gas or liquid and places where chemicals handled.
There is a danger of parts being deteriorated, smoking and
burning.
Avoid using it in a place with much dust.
If dust accumulates in the air inlet, remove it promptly.
