1. If there is a possibility of an accident caused by errors or malfunctions of this product,
install external protection circuit to prevent the accident.
2. 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)
3. To prevent defection or malfunction of this product, supply proper power voltage in
accordance with the rating.
4. To prevent electric shock or malfunction of this product, do not supply the power until the
wiring is completed.
5. Since this product is not designed to explosion-protective structure, do not use it at the
places which have flammable or explosive gas.
6. Do not disassemble, modify, revise or repair this product. This may cause malfunction,
electric shock or fire.
7. Attach or detach this product while the power is off. Otherwise, it may cause malfunction
or electric shock.
8. It you use the product with methods other than specified by the manufacturer, there may
be bodily injuries or property damages.
9. Due to the danger of electric shock, use this product installed onto a panel while an
electric current is applied.
1. The contents of this manual may be changed without prior notice.
2. Please check whether the product you purchased is the exactly same as you ordered.
3.Please check whether the product has no damage or abnormality during
delivery.
4. Do not use this product with time setting “0”
5. Change setting time in condition of “Power OFF”. If change setting time in condition of
“Power On”, reset should be done.
6. Do not use the product at the places which have corrosive(especially noxious gas or
ammonia) or flammable gas.
7. Do not use this product at any place with direct vibration or impact.
8. Do not use this product at any place with liquid, oil, medical substances, dust, salt or iron
contents. (Pollution level 1 or 2)
9. Do not polish this product by substances such as alcohol or benzene.
10. Do not use this product at any place with excessive induction trouble, static electricity or
magnetic noise.
11. Do not use this product at any place with possible thermal accumulation due to direct
sunlight or heat radiation.
12. Install this product at place under 2,000m in altitude.
13. When the product gets wet, the inspection is essential because there is danger of an
electric leakage or fire.
14.
If there is an excessive noise from power supply, it is recommended to use insulating
transformer and noise filter. The noise filter must be attached to the panel grounded and
wiring between the filter output side and power supply terminal should be as short as
possible.
15. If gauge cables are arranged too closely, the effect on noise may occur.
16. Do not connect anything to the unused terminals.
17. After checking polarity of terminal, connect wires to the right position.
18. When this product is connected to a panel, use a circuit breaker or switch approved by
IEC947-1 or IEC947-3.
19. Install the circuit breaker or switch at near place for convenient use.
20. Write down on a label that the operation of circuit breaker or switch disconnects the
power since the devise is installed.
21. For the continuous and safe use of this product, the periodic maintenance is
recommended.
22.
Some parts of this product have limited life span, and others are changed by their usage.
23. The warranty period of this product including parts is one year if this product is properly used.
24. When power is on, the preparation period of contact output is required. In case of using
signals of external interlock circuit, use a delay Relay.
Safety Information
Do not touch or contact the input/output terminals because they may cause electric
shock.
