personnel.
6.1 Mechanical mounting
6.1.1 Selecting the installation site
The space required is dependent on the design variant of the process transmitter.
The case head is rotatable through 330° and the display and operating unit can be
inserted and oriented in 90° steps. Thus the process transmitter can be adjusted to the
installation site (see figures under chapter 4.1 “Description”).
Select an installation site that has sufficient space for:
■ Carrying out a safe electrical mounting.
■ Being able to use the operating elements following the mounting.
