Labels Read all labels carefully before installing the equipment!
The 2150EX and its components are clearly labeled with color
and/or text so you know what can be located in a safe or haz-
ardous area (see figure below). For example, on the label shown
below, light blue is used to indicate the intrinsically safe end and
yellow to indicate the non-protected end of the cable and con-
nector.
Example of Safe and Hazardous Area Labeling on RS232EX Cable
Some system components have an X marking, as shown in the
example below. The X marking indicates that there are special
conditions that must be met to ensure intrinsic safety. In the case
of the sensor cable, there is a danger of static electricity. The
cable is labeled with a warning telling you that you should not
rub the sensor with a dry cloth, as this might generate static
electricity.
