• 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.

• 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.

■ Function switch configuration
1. Shut off the power of TF4A.
2. Select the input switch attached to the side of the case according to
the input logic voltage(PNP) or non voltage(NPN) you want to
use.
3. If you supply power to TF4A after selection is complete, the timer
operates according to the selected voltage (PNP)/non-voltage (NPN)
input status.
※Note) Change the voltage input and no-voltage input selection
after the power is turned off.
