1.9.2 ATEX Certification

WARNING

• Do not open the cover when energized.

• When the ambient temp.≥70°C,

Use the heat-resisting cable≥90°C

• Take care not to generate mechanical

sparking when access to the instrument and

peripheral devices in hazardous locations.

• Electrostatic charge may cause an explosion

hazard.

Avoid any actions that cause the generation

of electrostatic charge, such as rubbing with

a dry cloth on coating face of product.

(1) Technical Data

A) ATEX Intrinsically Safe Type (Ex ia)
Caution for ATEX Intrinsically Safe Type.

NOTE

Keep the safety use conditions for both 1G and

1D when used in the hazardous gas and dust

area.

• Certificate: KEMA 08ATEX0114 X

Note 2. Ratings

Type of Protection:

II 1G Ex ia IIB/IIC T4

II 1D Ex iaD 20 IP65 T100°C

II 1D Ex tD A20 IP65 T100°C

Maximum Surface Temperature for dust proof.:

T100°C

Ambient Temperature Ex ia or Ex iaD:

–40°C to +60°C

Ambient Temperature Ex tD: –40°C to +80°C

Ambient Humidity: 0 to 100%RH

(No condensation)

Degree of Protection of the Enclosure: IP65

Electrical Parameters:

For Ex ia IIC or Ex iaD

Ui = 24.0 V, Ii = 250 mA, Pi = 1.2 W,

Cint = 1.76 nF, Lint = 0 μH

or

For Ex ia IIB/ IIC or Ex iaD (FISCO model)

Ui = 17.5 V, Ii = 380 mA, Pi = 5.32 W,

Cint = 1.76 nF, Lint = 0 μH

Note 3. Installation

All wiring shall comply with local installation

requirements.

(Refer to the installation diagram)

Note 4. Maintenance and Repair

The instrument modification or parts

replacement by other than authorized

representative of Yokogawa Electric

Corporation is prohibited and will void KEMA

Intrinsically safe Certification.

Note 5. Special Conditions for Safe Use

Because the enclosure of the Valve Positioner

is made of aluminium, if it is mounted in an area

where the use of category 1G apparatus is

required, it must be installed such, that, even in

the event of rare incidents, ignition sources due

to impact and friction sparks are excluded.

Once used as apparatus of equipment category

1D in type of protection Ex tD, the valve

positioner is no longer suitable as apparatus

of equipment category 1G or 1D in type of

protection Ex ia or Ex iaD.

Note 6. Installation Instructions

When used in a potentially explosive

atmosphere, requiring the use of apparatus of

equipment category 1D, suitable certified cable

entry devices or certified blanking elements

with a degree of ingress protection of at least

IP6X according to EN 60529 shall be used and

correctly installed.

Note 7. Installation

When used in potentially explosive atmosphere

for category 1D, need not use safety barrier.
