hazardous location. When used in combustible dust

environment, cable entry in accordance with IP66 or

higher level should be applied.

4. Obey the warning “Keep tight when the circuit is alive.”

5. End users are not permitted to change any internal

components.

6. During installation, use and maintenance of this product,

observe the following standards:

GB3836.13-1997 “Electrical apparatus for explosive gas

atmospheres Part 13: Repair and overhaul for apparatus

used in explosive gas atmospheres”

GB3836.15-2000 “Electrical apparatus for explosive gas

atmospheres Part 15: Electrical installations in hazardous

area (other than mines)”

GB3836.16-2006 “Electrical apparatus for explosive gas

atmospheres Part 16: Inspection and maintenance of

electrical installation (other than mines)”

GB50257-1996 “Code for construction and acceptance of

electric device for explosion atmospheres and fire hazard

electrical equipment installation engineering”.

GB12476.2-2006 “Electrical apparatus for use in the

presence of combustible dust Part 1-2: Electrical apparatus

protected by enclosures and surface temperature

limitation-Selection, installation and maintenance”

GB15577-2007 “Safety regulations for dust explosion

prevention and protection”

I3 China Intrinsic Safety

Certificate: GYJ13.1362X; GYJ101312X [Flowmeters]

Standards: GB3836.1-2010, GB3836.4-2010,

GB3836.20-2010, GB12476.1-2000

Markings: Ex ia IIC Ga T4/T5

Special Conditions for Safe Use (X):

1. Symbol “X” is used to denote specific conditions of use:

a.If the apparatus is fitted with an optional 90V transient

suppressor, it is not capable of withstanding the 500V

insulation test for 1 minute. This must be taken into

account when installing the apparatus.

b.The enclosure may be made of aluminum alloy and

given a protective polyurethane paint finish; however,

care should be taken to protect it from impact or

abrasion if located in Zone 0.

2. The relation between T code and ambient temperature

range is:

3. Intrinsically Safe parameters:

Note 1: FISCO parameters apply to both Group IIC and IIB.

Note 2: [For Flowmeters] When 644 Temperature

Transmitter is used, it should be used with Ex-certified

associated apparatus to establish explosion protection

system that can be used in explosive gas atmospheres.

Wiring and terminals should comply with the instruction

manual of both 644 Temperature Transmitter and

associated apparatus. The cables between 644

Temperatures Transmitter and associated apparatus

should be shielded cables (the cables must have insulated

shield). The shielded cable has to be grounded reliably in a

non-hazardous area.

4. Transmitters comply with the requirements for FISCO field

devices specified in IEC60079-27:2008. For the connection

of an intrinsically safe circuit in accordance with FISCO

Model, FISCO parameters are listed in the table above.

5. The product should be used with Ex-certified associated

apparatus to establish explosion protection system that

can be used in explosive gas atmospheres. Wiring and

terminals should comply with the instruction manual of

the product and associated apparatus.

6. The cables between this product and associated apparatus

should be shielded cables (the cables must have insulated

shield). The shielded cable has to be grounded reliably in a

non-hazardous area.

7. End users are not permitted to change any intern

components but to settle the problem in conjunction with

the manufacturer to avoid damage to the product.

8. During installation, use and maintenance of this product,

observe the following standards:

GB3836.13-1997 “Electrical apparatus for explosive gas

atmospheres Part 13: Repair and overhaul for apparatus

used in explosive gas atmospheres”

GB3836.15-2000 “Electrical apparatus for explosive gas

atmospheres Part 15: Electrical installations in hazardous

area (other than mines)”

GB3836.16-2006 “Electrical apparatus for explosive gas
