Special Conditions for Safe Use (X):
1. The relation between ambient temperature arrange
and temperature class is as follows:
T
a
-50 °C to +80 °C
-50 °C to +65 °C
When used in a combustible dust environment, the
maximum ambient temperature is 80 °C.
2. The earth connection facility in the enclosure should
be connected reliably.
3. Cable entry certified by notified body with type of
protection Ex d IIC in accordance with GB3836.1-2000
and GB3836.2-2000, should be applied when
installed in a 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, GB3836.15-2000,
GB3836.16-2006, GB50257-1996, GB12476.2-2006,

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 90 V
transient suppressor, it is not capable of
withstanding the 500 V 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.

Note 2: [For Flowmeters] When Rosemount 644
Temperature Transmitter is used, the Rosemount 644
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 Rosemount 644 and associated apparatus.
The cables between Rosemount 644 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.
