The field transmitter can be installed as an "associated apparatus" in the safe area, where the field
transmitter operates as a normal barrier module. Also, the field transmitter can be installed as
Category 2 equipment in Zone 1, where it is battery operated.
Since the field transmitter can be installed in the "safe area" as an "associated apparatus" or as an
intrinsically safe apparatus in Zone 1 with an intrinsically safe output to Zone 0, it is important for the
safety of the user that the installation instructions from the manufacturer are obeyed.
The check boxes on the product marking plate identify the marking in which the field transmitter is
compliant. By default, the marking will be for installation in a safe zone. If the DC and SCADA
connections are not used, a flip cover can be closed. When the flip cover is closed, the other marking
shows, which is for installation in Zone 1. The flip cover system makes sure that the marking is
correct even if the flip cover is accidentally removed.
