product. We will not be held responsible after the product has been modified, changed or dis-assembled.
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.
When necessary, this products is to be repaired only by us or our authorized agents. It is important that this product cannot be used in
hazardous environments (facilities such as nuclear power control system or life support equipment) without our written consent.
CAUTION on MOUNTING
Confirm connections to input/output terminals are correct as indicated in the instruction manual before switching on.
Input voltage, Output current, Output power, ambient temperature and ambient humidity should be kept within specifications,
otherwise the product will be damaged.
Input 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 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, please consider penetration of above
foreign material in the power supply by installing filter, to prevent trouble or malfunction.
