NOTICE
Danger of overheating
‣
Ensure that the temperature at the lower end of the transmitter housing does not
exceed 80 °C (176 °F).
‣
Ensure that sufficient convection takes place at the transmitter neck.
‣
When using in potentially explosive atmospheres, observe the information in the
device-specific Ex documentation. For detailed information on the temperature tables,
see the separate document entitled "Safety Instructions" (XA) for the device.
‣
Ensure that a sufficiently large area of the transmitter neck remains exposed. The
uncovered part serves as a radiator and protects the electronics from overheating and
excessive cooling.
‣
If operating outdoors:
Avoid direct sunlight, particularly in warm climatic regions.
