INSTRUCTION MANUAL
DANGER
Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury
CAUTION
Indicates a potentially hazardous situation which, if not avoided, may result in minor injury or property damage
• Any use of the product other than those ecified by the
manufacturer may result in personal injury or property
damage.
• If there is a possibility that a malfunction or abnormality
of this product may lead to a serious accident to the system,
install an appropriate protection circuit on the outside.
• Since this product is not equipped with a power switch
and fuse, install them separately on the outside.
(fuse rating: 250 VAC 0.5 A).
• Please supply the rated power voltage, in order to
prevent product breakdowns or malfunctions.
• To prevent electric shocks and malfunctions, do not
supply the power until the wiring is completed.
• The product does not have an explosion-proof structure,
so avoid using it in places with flammable or explosive
gases.
• Never disassemble, modify, process, improve or repair
this product, as it may cause abnormal operations,
electric shocks or fires.
• Please disassemble the product after turning OFF the
power. Failure to do so may result in electric shocks,
product abnormal operations or malfunctions.
• Please use this product after installing it to a panel,
because there is a risk of electric shock.
• The contents of this manual may be changed without prior notification.
• Please make sure that the product specifications are the same as you ordered.
• Please make sure that there are no damages or product abnormalities occurred during shipment.
• Please use the product in places where corrosive gases (especially harmful gases,
ammonia, etc.) and flammable gases are not generated.
• Please use the product in places where vibrations and impacts are not applied directly.
• Please use the product in places without liquids, oils, chemicals, steam, dust, salt, iron, etc.
• Please do not wipe the product with organic solvents such as alcohol, benzene, etc.
(use neutral detergents).
• Please avoid places where large inductive interference, static electricity, magnetic
noise are generated.
• Please avoid places with heat accumulation caused by direct sunlight, radiations, etc.
• Please use the product in places with elevation below 2000 m.
• When water enters, short circuit or fire may occur, so please inspect the product
carefully.
• When there is a lot of noise from the power, we recommend to use insulation transformer
and noise filter. Please install the noise filter to a grounded panel, etc. and make the
wiring of noise filter output and power supply terminal as short as possible.
• Tightly twisting the power cables is effective against noise.
• Do not wire anything to unused terminals.
• Please wire correctly, after checking the polarity of the terminals.
• When you install this product to a panel, please use switches or circuit
breakers compliant with IEC60947-1 or IEC60947-3.
• Please install switches or circuit breakers at close distance for user convenience.
• We recommend regular maintenance for the continuous safe use of this product.
• Some components of this product may have a lifespan or deteriorate over time.
• The warranty period of this product, is 1 year, including its accessories, under
normal conditions of use.
• The preparation period of the contact output is required during power supply.
If used as a signal to external interlock circuit, etc. please use a delay relay together.
• The input/output terminals are subject to electric
shock risk. Never let the input/output terminals come
in contact with your body or conductive substances.
