Intrinsically Safe MFTs can be identified by model number (see table above or Intrinsically Safe Control Drawing in
the Appendix of this manual) or by the Intrinsically Safe WARNING label affixed to the MFT enclosure. See the label
sample below.
WARNING label for Intrinsically Safe MFT Units
All MFTs have a battery door complete with captive screw to secure the door to the enclosure. For Intrinsically Safe
MFTs this battery door hardware prevents the accidental ejection of batteries. See the Installation and Removal of
Batteries section of this manual for more details.
WARNING: Serious injury or death may result from explosions. Do not make connection to the DB – 9
connection port or to the AC adapter jack in a hazardous area
WARNING: Serious injury or death may result from explosions. Before making electrical connections to an
Intrinsically Safe MFT at the V/Com/mA jacks or at the HART jacks, verify the instruments in the loop are
installed in accordance with intrinsically safe field wiring practices.
Note: Restrictions apply to the use of Intrinsically Safe MFT units in hazardous areas. Refer to the
Intrinsically Safe Control Document in the Appendix for exact details. Meriam reserves the right to revise the
Control Document without notice. Contact Meriam for the current Intrinsically Safe Control Document.
Note: Intrinsically Safe modules RTD1000, RIO4000, TIO0110 and VMA0055 require the use of electrical
connections and leads. Any electrical connections made to Intrinsically Safe modules installed in an
Intrinsically Safe MFT base unit must be made in non-hazardous areas only. Refer to the Intrinsically Safe
Control Document in the Appendix for details.
