Warning
Caution

Warning

1.Fail-safe device must be installed when using the unit with machinery that may cause seri-

ous injury or substantial economic loss. (e.g. nuclear power control, medical equipment,
ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster
prevention devices, etc.)

Failure to follow this instruction may result in personal injury, economic loss or re.

2.Do not use the unit in the place where ammable/explosive gas, high humidity, direct sun-

light, radiant heat, vibration, impact, or salinity may be present.

Failure to follow this instruction may result in explosion or re.

3.Do not connect, repair, or inspect the unit while connected to a power source.

Failure to follow this instruction may result in electric shock or malfunction.

4.For installing the unit, ground it exclusively and use over AWG 11(4mm²) ground cable.

Failure to follow this instruction may result in electric shock.

5.Do not disassemble or modify the unit.

Failure to follow this instruction may result in re or electric shock.

6.Check 'Connections' before wiring.

Failure to follow this instruction may result in re.

Caution

A

1.Use the unit within the rated specications.

Failure to follow this instruction may result in re or product damage.

2.Use a dry cloth to clean the unit, and do not use water or organic solvent.

Failure to follow this instruction may result in re or electric shock.

3.Keep the product away from metal chip, dust, and wire residue which ow into the unit.

Failure to follow this instruction may result in re or product damage.

Cautions During Use

~

1. Follow instructions in 'Cautions during Use'.

O herwise, it may cause unexpected accidents.

2. Power supply should be insulated and limited voltage/current or Class 2, SELV power
supply device.

3. Keep away from high voltage lines or power lines to prevent inductive noise.

Do not use near he equipment which generates strong magnetic force or high frequency

noise.

4. Install a power switch or circuit breaker in the easily accessible place for supplying or dis­connecting the power.

5. The explosion-proof standard of his unit is Ex d IIC T6, protection structure of this unit is
IP67 and the range of max. surface temperature is below 85℃.

Use the veried explosion-proof electric connection (cable gland or sealing t ing)

6. This unit may be used in the following environments.

①Indoors (in the environment condition rated in 'Specications')
②Altitude max. 2,000m
③Pollution degree 2
④installation Category II

The explosion-proof unit is certied and the same specications which is reported to
