█ Safety

•

For the safety and protection of the product and the system connected to it, please follow the manual and use it.

•We do not have responsibility for all the damages caused by using the products
without following the introductions in the manual or careless use of it.

•For the safety and protection of the product and the system connected to it,
you must install a separate circuit outside the product when you are required.

•

Do not dissemble, repair and remodel it as you pleases. It may cause electric shock, fire and malfunction.

•

Do not give a shock to the product. It may cause damage and malfunction of the product.

•We do not have responsibility and guarantee about the product for any of the contents
other than the terms of our company's quality assurance.

•

When a user or others are harmed by the defection which is unexpected by our company or natural

disaster while using the product, we do not have any responsibility for the loss or indirect damage.

Checking products

Check the following items with the package.

Main body 4 parts for 6 pin terminal 1 part for 5 pin terminal

█ Installation

• Use it after installing the product on panel since there is a risk of electric shock.

• Do not block radiators of the product. It may cause malfunction of the product.

• Do not install it in following places :

· The place for contacting the part while people are unconscious.

· A place where there is a direct electric vibration or shock.

· A place where there is a corrosive gas or a combustional gas.

· A place where there is a high temperature change.

· A place where the temperature is extremely high or low.

· A place where there is a direct sunlight.

· A place where there is a high impact of electromagnetic waves.

· A place where there is a high humidity.

· A place where there are products that are highly flammable in case of fire.

· A place where there is a lot of dust and salt.

█ Wiring

• Wire it after all the powers of the instruments are shut off.

•

It works at 24 V DC. When using a power other than the rating, it may cause an electric shock and fire.

•

When connecting many of ML Series to make one module, connect a power to only one unit.

• When connecting to 24 V DC power, use it in accordance with the rating after calculating total
consumption of electric power. Using a power supply of lower capacity than the total
consumption of electric power of the module may cause malfunction of the product.

• Do not work with wet hand. It may cause electric shock.

• For installation and way of use, use the manual and follow it.

• Refer to the installation method for the content and about the connection. Never connect to
gas pipe, telephone wire, and lighting rod. It may cause explosion and fire.

•Do not supply power before finishing the connections among the parts of this product.

• There is a possibility of electric shock while applying electric current. So, do not come in contacts with any parts.

• For I/O signal line, wire it after separating the instrument's power line and load line to

prevent the impact of induction noise.

•For instrument's power, wire it to avoid a noise impact from the power. We recommend

to use noise filter if it is easy to get impact of the noise.

•For connected module's power supply, supply it to only one module. Power is supplied

among all connected modules.

•For power, select the product in accordance with inrush current when the connected

module's consumption voltage and Power are ON.

█ Loder cable

•Be sure to use the cable supplied by the manufacture. Connecting another cable such as
a general USB cable may cause malfunction.

█ Customer Support

•

The guarantee period is 1 year from the date of purchasing the product. When we would find

any malfunction of the product since you use it normally by the manual, we would repair it for free

•

The cost of repair after the guarantee period will be expensed according to our company's standard.

•

The costs of the repair for malfunction during the guarantee period are expensed as follows :

· Malfunction by user's mistake.

· Malfunction by natural disasters.

· Malfunction by moving after the product is installed.

· Malfunction by a change of the product randomly or damage.

· Malfunction by disorder of power supply due to unstable power supply.

•

Please contact our company's sales team or distributor when you need the A/S for malfunction or etc.
