Before starting the installation, check the following:

WARNING Protected installation using galvanic isolators or Zener barriers is mandatory in a hazardous environment.
CAUTION When planning the wiring of your application, note that Channel 1 (CH1) must always be wired. The transmitter receives power through the Channel 1 screw terminals, and does not power on if only Channel 2 (CH2) is wired.
CAUTION To maintain the required Ex protection, do not install the transmitter model with an LCD display in a location where it is exposed to direct sunlight.
