damages as required by law.

USING THE PRODUCT SAFELY

WARNING

CAUTION

■ Do not remove the product's covers and panels

Never remove the product's covers and panels for any purpose.

Otherwise, the user's electric shock or fire may be incurred.

■ Warning on using the product

Warning items given below are to avoid danger to user's body and life and avoid the damage or deterioration of the

product. Use the product, observing the following warning and caution items.

■ Warning items on power supply

● Power supply voltage

The rated power supply voltages of the product are 100, 120, 220 and 240VAC. The rated power supply voltage for

each product should be confirmed by reading the label attached on the back of the product or by the “rated” column

shown in the instruction manual. The specification of power cord attached to the products is rated to 125VAC for

all products which are designed to be used in the areas where commercial power supply voltage is not higher

than 125VAC. Accordingly, you must change the power cord if you want to use the product at the power supply

voltage higher than 125VAC. If you use the product without changing power cord to 250VAC rated one, electric

shock or fire may be caused. When you used the product equipped with power supply voltage switching system,

please refer to the corresponding chapter in the instruction manuals of each product.

● Power cord

(IMPORTANT) The attached power cord set can be used for this device only.

If the attached power cord is damaged, stop using the product and call us or your local dealer.

If the power cord is used without the damage being removed, an electric shock or fire may be caused.

● Protective fuse

If an input protective fuse is blown, the product does not operate. For a product with external fuse holder, the fuse

may be replaced. As for how to replace the fuse, refer to the corresponding chapter in the instruction manual.

If no fuse replacement procedures are indicated, the user is not permitted to replace it. In such case, keep the

case closed and consult us or your local dealer. If the fuse is incorrectly replaced, a fire may occur.

■ Warning item on Grounding

If the product has the GND terminal on the front or rear panel surface, be sure to ground the product to safely use it.

■ Warnings on Installation environment

● Operating temperature and humidity

Use the product within the operating temperature indicated in the “rating” temperature column.

If the product is used with the vents of the product blocked or in high ambient temperatures, a fire may occur.

Use the product within the operating humidity indicated in the “rating” humidity column.

Watch out for condensation by a sharp humidity change such as transfer to a room with a different humidity.

Also, do not operate the product with wet hands. Otherwise, an electric shock or fire may occur.

● Use in gas

Use in and around a place where an inflammable or explosive gas or steam is generated or stored may result in an

explosion and fire. Do not operate the product in such an environment.

Also, use in and around a place where a corrosive gas is generated or spreading causes a serious damage to the

product. Do not operate the product in such an environment.

● Installation place

Do not insert metal and inflammable materials into the product from its vent and spill water on it.

Otherwise, electric shock or fire may occur.

USING THE PRODUCT SAFELY

■ Do not let foreign matter in

Do not insert metal and inflammable materials into the product from its vent and spill water on it.

Otherwise, electric shock or fire may occur.

■ Warning item on abnormality while in use

If smoke or fire is generated from the product while in use, stop using the product, turn off the switch, and remove the

power cord plug from the outlet. After confirming that no other devices catch fire, ask us or your local dealer.

■ Input / Output terminals

Maximum input to terminal is specified to prevent the product from being damaged.

Do not supply input, exceeding the specifications that are indicated in the "Rating" column in the instruction manual of

the product. Also, do not supply power to the output terminals from the outside.

Otherwise, a product failure is caused.

■ Calibration

Although the performance and specifications of the product are checked under strict quality control during shipment

from the factory, they may be deviated more or less by deterioration of parts due to their aging or others.

It is recommended to periodically calibrate the product so that it is used with its performance and specifications stable.

For consultation about the product calibration, ask us or your local dealer.

■ Daily Maintenance

When you clean off the dirt of the product covers, panels, and knobs, avoid solvents such as thinner and benzene.

Otherwise, the paint may peel off or resin surface may be affected. To wipe off the covers, panels, and knobs, use a

soft cloth with neutral detergent in it.

During cleaning, be careful that water, detergents, or other foreign matters do not get into the product.

If a liquid or metal gets into the product, an electric shock and fire are caused.

During cleaning, remove the power cord plug from the outlet.

Use the product correctly and safely, observing the above warning and caution items.

Because the instruction manual indicates caution items even in individual items, observe those caution items to correctly

use the product.

If you have questions or comments about the manuals, ask us or E-Mail us.
