• Do not use this product at any place with liquid, oil, medical substances, dust, salt or iron contents.
•Do not polish this product with substances such as alcohol or benzene.
• Do not use this product at any place with a large inductive difficulty or occurring static electricity or magnetic noise.
• Do not use this product at any place with possible thermal accumulation due to direct sunlight or heat radiation.
•Install this product at place under 2,000 m in altitude.
• When the product gets wet, the inspection is essential because there is a danger of electric leakage or fire.
• If there is excessive noise from the power supply, using insulating transformer or noise filter is
recommended. The noise filter must be attached to a panel which is already connected to a ground and
the wire between the filter output and power supply terminal must be as short as possible.
•If puttig power cables closely together then It is effective against noise.
•Do not connect anything to the unused terminals.
•After checking the polarity of terminal, connect wires at the correct position.
• When this product is connected to a panel, use a circuit breaker or switch approved with IEC60947-1 or IEC60947-3.
•Install the circuit breaker or switch at near place for convenient use.
• Write down on a label that if the circuit breaker or switch is operating then the power will be
disconnected since the circuit breaker or switch is installed.
• For the continuous and safe use of this product, the periodical maintenance is recommended.
• Some parts of this product have limited life span, and others are changed by their
• The warranty period for this product including parts is one year if this product is properly used
• If there is a possibility of an accident caused by errors or malfunctions of this product, install external
protection circuit to prevent the accident.
• This product does not contain an electric switch or fuse, so the user needs to install a separate electric
switch or fuse externally. (Fuse rating : 250 V 0.5 A)
• To prevent defection or malfunction of this product, supply proper power voltage in accordance with the rating.
• To prevent electric shock or malfunction of product, do not supply the power until the wiring is completed.
• Since this product is not designed with explosion-protective structure, do not use it any place with
flammable or explosive gas.
• Do not decompose, modify, revise or repair this product. This may be a cause of malfunction, electric shock or fire.
• Reassemble this product while the power is OFF. Otherwise, it may be a cause of malfunction or electric shock.
• If you use the product with methods other than specified by the manufacturer, there may be bodily
injuries or property damages.
• Due to the danger of electric shock, use this product installed onto a panel while an electric current is applied.
There is a danger of occurring electric shock in the input/output terminals so please never let your body or
conductive substance is touched.
