Special Condition for Safe Use (X):
1. If the equipment is fitted with an optional 90 V transient
suppressor, it is not capable of withstanding the 500 V
insulation test required by ABNT NBR IRC
60079-11:2008. This must be taken into account when
installing the equipment.

Special Conditions of Use (X):
1. Symbol “X” is used to denote specific conditions of use:
The Ex d blanking elements, cable glands, and wiring
shall be suitable for a temperature of 90°C
This device contains a thin wall diaphragm.
Installation, maintenance and use shall take into
account the environment conditions to which the
diaphragm will be subjected.
2. The relation between T code and ambient temperature
range is:
3. The earth connection facility in the enclosure should be
connected reliably.
4. During installation, use and maintenance of the
product, observe the warning “Don’t open the cover
when the circuit is alive.”
5. During installation, there should be no mixture harmful
to flameproof housing
6. Cable entry and conduit, certified by NEPSI with type of
protection Ex d IIC and appropriate thread form, should
be applied when installed in a hazardous location.
Blanking elements should be used on the redundant
cable entries.
7. End users are not permitted to change any internal
components, but to settle the problem in conjunction
with the manufacturer to avoid damage to the product.
8. Maintenance should be done in a non-hazardous
location.
9. During installation, use and maintenance of this
product, observe the following standards:
GB3836.13-1997, GB3836.15-2000, GB3836.16-2006,

I3 China Intrinsic Safety
Certificate: GYJ12.1295X; GYJ101320X [Flowmeters]
Standards: GB3836.1-2010, GB3836.4-2010,
GB3836.20-2010
Markings: Ex ia IIC T4 Ga
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 comply with the
requirements for FISCO field devices in GB3836.19-2010
Note 2: [For Flowmeters] When 644 temperature
transmitter is used, the 644 temperature transmitter
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. 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.
