warnings before using this product. Incorrect usage could lead to an electrical shock, damage to the unit or a fire 
hazard.

DANGER

Never use this product in locations where flammable gas or ignitable substances are present.

INSTALLATION WARNING

• When  installing,  ensure  that  work  is  done  in  accordance  with  the  instruction  manual.  When  installation  is 

improper, there is risk of electric shock and fire.

• Installation  shall  be  done  by  Service  personnel  with  necessary  and  appropriate  technical  training  and 

experience. There is a risk of electric shock and fire.

• Do not cover the product with cloth or paper etc. Do not place anything flammable around. This might cause 

damage, electric shock or fire.

WARNING on USE

• Do not touch this product or its internal components while circuit in operation, or shortly after shutdown. You 

may receive a burn.

• While  this  product  is  operating,  keep  your  hands  and  face  away  from  it  as  you  may  be  injured  by  an 

unexpected situation.

• There are cases where high voltage charge remains inside the product. Therefore, do not touch even if they are 

not in operation as you might get injured due to high voltage and high temperature. 
You might also get electric shock or burn.

• Do not make unauthorized changes to this product nor remove the cover as you might get an electric shock or 

might damage the product. We will not be held responsible after the product has been modified, changed or 
dis­assembled.

• Do not use this product under unusual condition such as emission of smoke or abnormal smell and sound etc. 

Please stop using it immediately and shut off the product.
It might lead to fire and electric shock. In such cases, please contact us. Do not attempt repair by yourself, as it 
is dangerous for the user.

• Do  not  operate  and  store  these  products  in  environments  where  condensation  occurs  due  to  moisture  and 

humidity. It might lead fire and electric shock.

• Do not drop or apply shock to this product. It might cause  failure. Do not operate these products mechanical 

stress is applied.

CAUTION on MOUNTING

• Confirm  connections  to  input/output  terminals  are  correct  as  indicated  in  the  instruction  manual  before 

switching on.

• Input/output line, please use the wires as short and thick as possible.
• Do not use this product in special environment with strong electromagnetic field, corrosive gas or conductive 

substances and direct sunlight, or places where product is exposed to water or rain.

• Mount  this  product  properly  in  accordance  with  the  instruction  manual,  mounting  direction  and  shall  be 

properly be ventilated.

• Please shut down the input when connecting input and output of the product.
• When installing  in environment where conductive foreign, dust and liquid may be present,
