INSTRUCTION MANUAL
We appreciate you for purchasing HanYoung NUX Co.,Ltd
product. Before using the product you have purchased,
check to make sure that it is exactly what you ordered.
Then, please use it following the instructions below.
Safety information
Before you use, read safety precautions carefully, and use this product
properly. The precautions described in this manual contain important
contents related with safety; therefore, please follow the instructions
accordingly. The precautions are composed of DANGER, WARNING and
CAUTION.
DANGER
There is a danger of occurring electric shock in the input/output terminals
so please never let your body or conductive substance is touched.
WARNING
1. If there is a concern about a serious accident caused by a malfunction
or abnormality of this product, please install an external protection
circuit and devise a scheme for preventing an 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: 250V 0.5A)
3. There is voltage output of 24V built in this indicator.
4. Do not use load of more than 700mA.
5. To prevent defection or malfunction of this product, apply a proper
power voltage in accordance with the rating.
6. When altering the usage input range (SH, SL), ensure this is altered
prior to anything else. When the SH, SL are altered, it impacts the
other data and may generate unwanted results.
7. To prevent electric shock or malfunction of product, do not supply the
power until the wiring is completed.
8. Since this product is not designed with explosion-protective structure,
do not use it any place with flammable or explosive gas.
9. Do not decompose, modify, revise or repair this product. This may be a
cause of malfunction, electric shock or fire.
10. Reassemble this product while the power is OFF. Otherwise, it may be
a cause of malfunction or electric shock.
11. If you use the product with methods other than specified by the
manufacturer, there may be bodily injuries or property damages.
12. There is a possibility of occurring electric shock so please use this
product after installing it onto a panel while it is operating.
CAUTION
1. The contents of this manual may be changed without prior notification.
2. Make sure that there is no damage or abnormality of the product
during the delivery.
3. Use this product within the range of the operating ambient
temperature, 0 ~ 50 (When it is closely installed Max 40
ambient humidity, 20 ~ 90 % RH (No condensation).
4. Do not use this product at any place with occurring corrosive
(especially noxious gas or ammonia) or flammable gas.
5. Do not use this product at any place with direct vibration or impact.
6. Do not use this product at any place with liquid, oil, medical
substances, dust, salt or iron contents. (Use at Pollution level 1 or 2)
7. Do not polish this product with substances such as alcohol or benzene.
(Use neutral detergent.)
8. Do not use this product at any place with a large inductive difficulty or
occurring static electricity or magnetic noise.
9. Do not use this product at any place with possible thermal
accumulation due to direct sunlight or heat radiation.
10. Install this product at place under 2,000m in altitude.
11.When the product gets wet, the inspection is essential because there is
danger of an electric leakage or fire.
12.To avoid an effect of inductive noise to input signal cables, use the
product after separating the input signal cables from power, output and
load cables.
13. Separate an input signal cable from an output signal cable. If
separating is not possible, please use the input signal cable after
shielding it.
14. If there is excessive noise from the power supply, using insulating
transformer and noise filter is recommended. The noise filter must be
attached to a panel which is already connected to a ground and the bar
wire between the filter output side and power supply terminal must be
short as possible.
15.If twisting the power cables closely together then it is effective against
noise.
