Understand the risk. 

This product generates high voltage and energy. 
An  electrician  or  equivalent  knowledge  must  read  the 
instruction manual to the end and familiarize yourself with 
the proper use and danger of the product. 
If  you  want the product to  be handled by another person, 
limit  it  to  those  with  knowledge  of  electricity,  and  have 
people who are familiar with correct use and danger of the 
product conduct education and training before handling it. 
Or handle the product under the supervision of those who 
are familiar with the proper use and danger of the product. 
Persons, with the exception of the above, must not handle 
the product. 
 

Do not open the product case and panel. 

Do  not  disassemble,  remodel,  or  repair  by  opening  the 
product  case  and  panel  yourself.  There  is  a  high  voltage 
area inside, which may possibly cause electric shock and 
fire.  Never  remove  the  case  and  panel  of  the  product, 
since  the  safety  and  function  of  the  product  will  not  be 
guaranteed. 
 

It  is  not  suitable  for  use  in  places  where  there  is  a 
possibility of a child being present. 

The  product  is  designed  assuming  that  it  will  be  used  in 
places where there are only adults, such as factories and 
laboratories. Do not use it where there is a possibility of a 
child being present. 
 

Ensure  that  the  product  is  handled  only  by  a  limited 
number of people.

danger  of  the  product,  or  those  who  are  educated  and 
trained  by  them  should  install  the  product.  Any  other 
person  handling  the  product  may  cause  electric  shock, 
burns and injuries. 
 

Ground it. 

When  the  product  has  a  protective  ground  terminal  or 
GND terminal, connect it to the ground. If the input terminal 
of the product is an inlet type, connect to the power outlet 
with the ground using the supplied power cable or a power 
cable suitable for the area to be used. If it is not connected 
to  the  ground,  there  is  a  risk  of  electric  shock  and  fire, 
which is extremely dangerous. 
 

About power supply cable

product, it cannot be used for other products. 
In  the  case  of  a  product  that  does  not  include  a  power 
supply cable, you must purchase an optional power supply 
cable suitable for the operating environment and the area,
