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