USING THE PRODUCT SAFELY

WARNING

■ 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 a fire may be incurred.

■ Warning on using the product

The warning items given below are to avoid danger to the user's body and life and avoid the

damage and deterioration of the product.

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

■ Warning about Input Power

- Be sure to use the product within the source voltage rating marked on the product. Disobedience

to this warning may result in a fire. The rated source voltage of this product is AV 100V to 240V

(voltage fluctuation: within ±10%), single-phase. (AC250V max.)

-Use the AC power cable supplied with the product. Using another power cable may result in electric

shocks, electrocution or a fire. If the supplied AC power cable is damaged, stop using it and

contact your dealer or our distributor. Using the product with the damaged AC power cable may

result in electric shocks, electrocution or a fire.

-The product will not run if the input protection fuse has blown. The protection fuse is built in the

product and cannot be replaced by the user. If it has blown, contact your dealer or our distributor

without opening the case. Our serviceman will replace it. The user must not attempt to replace the

fuse at his/her discretion. Disobedience to this warning may result in electric shocks, electrocution

or a fire. IF 100V or 120V is to be changed into 220V or 230V, power cord need to be changed.

■ About Grounding

- Be sure to connect the ground wire of the three-wire power cable supplied with the product (or the

ground terminal of the three-pole plug of the cable) to the earth. The chassis of the product is

grounded to the GND.

■ Warning about Installation Conditions

- Use the product in the operation temperature range shown in the manual. Do not use the product

with the vent holes blocked or in a high ambient temperature. Disobedience to this warning may

result in a fire.

- Use the product in the operation humidity range shown in the manual. When moving it to a room at

different humidity, pay attention to dew condensation due to rapid humidity change. Do not handle

the product with wet hands. Disobedience to this warning may result in electric shocks,

electrocution or a fire.

- Do not use the product in or around a place where combustible gas, explosive gas or vapor is

produced or stored. Disobedience to this warning may result in explosion or a fire. Do not use the

product in or around a place where corrosive gas is produced or accumulated. Disobedience to this

warning may result in serious damages to the product.

- Do not put metallic or combustible objects or pour water into the product through the vent holes,

etc. Disobedience to this warning may result in electric shocks, electrocution or a fire.

■ Warning about Errors in Operation

- If the product products smoke, fire or odor in operation, stop using the product, turn it off, and

disconnect the AC power cable from the AC outlet. Make sure that the fire hasn’t spread to other

equipment, then contact your dealer or our distributor.

USING THE PRODUCT SAFELY

CAUTION

■ Caution about Installation Condition

- If this product is used in a place with much electrical noises, it may malfunction. Be sure to ground this

product using the GND terminal of the 3-core power cable or the GND lead wire of a 3P-2P conversion

plug, if used, when it is necessary to use this product in a place with much electrical noises.

■ External Control I/O Connector

- The external control I/O connector has its maximum rating. The maximum rating must not be

exceeded. Input or output over the maximum rating may result in damages to the product.

■Before Long-Term Unemployment

- If the product is to be unused for a long period of time, disconnect the AC power cable from the

AC outlet.

■Calibration

- The product has been inspected under strict quality control before shipment. It is, however, subject

to change in the performances due to aged deterioration of parts. To maintain its performances for

long, we recommend that it should be calibrated periodically. For calibration, please contact your

dealer or our distributor.

■Daily Maintenance

- Do not use thinner, benzine or other solvents to clean the case, panels, knobs, etc. of the

product. Such solvent may separate the coating or deteriorate the resin surface.

- Clean the case, panels, knobs, etc. lightly with soft cloth moistened with neutral detergent.

- Before cleaning the product, disconnect the power plug from the AC outlet. Be careful not

to put water, detergent or other foreign matters into the product.

USING THE PRODUCT SAFELY

CAUTION

■ Input/output terminal

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

Do not supply input, exceeding the specifications that are indicated in the "Rating" or "Caution on

use" column in the user's guide of the product. Otherwise, a product failure is caused.

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

Otherwise, a product failure is caused.

■When the product is left unused for a long time

Be sure to remove the power plug from the outlet.

(Calibration)

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

during shipment from the factory, they may slightly change because of secular changes in its parts.

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, call the dealer or the

company or each sales office where you bought the product.

(Daily maintenance)

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

thinner and benzene. Otherwise, paint may peel off or the 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, and 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 user's guide indicates caution items even in individual items, observe those

caution items to correctly use the product.

If you have questions or comments about the content of the user's guide, call the

company's sales office.
