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.
2. The relation between T code and ambient temperature range is:
3. Intrinsically Safe parameters:
Note
FISCO parameters apply to both Group IIC and IIB.
[For Flowmeters] When Rosemount 644 Temperature Transmitter is used, the
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 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.
