Shielding
• You achieve optimum shielding against disturbances if the shielding is connected on both sides
(in the cabinet and on the device). If potential equalization currents are expected in the plant,
only ground shielding on one side, preferably at the transmitter.
• When using in hazardous areas, you must observe the applicable regulations. Separate Ex
documentation with additional technical data and instructions is included with all Ex systems as
standard.

Connecting the Field Xpert SFX100
Compact, flexible and robust industry handheld terminal for remote configuration and for obtaining
measured values via the HART current output (4-20 mA). For details, see Operating Instructions
BA00060S/04/EN.
7.7
Connecting the Commubox FXA195
The Commubox FXA195 connects intrinsically safe transmitters with HART protocol to the USB
interface of a computer. This enables remote operation of the transmitter using the Hauser
operating program FieldCare. The power is supplied to the Commubox via the USB interface. The
Commubox is also suitable for connection to intrinsically safe circuits. For additional information,
refer to TI00404F/00/EN.
7.8
Post-connection check
m
Is the device or cable undamaged (visual check)?
m
Do the cables comply with the requirements ?
m
Do the cables have adequate strain relief?
