Mounting
Minimum distance to antennas
Fit the device so that there is a minimum clearance of 20 cm between antennas and
persons.
If a device is operated in an ambient temperature of more than 50 °C, the temperature of
the device housing may be higher than 70 °C. The device must therefore be installed so
that it is only accessible to service personnel or users that are aware of the reason for
restricted access and the required safety measures at an ambient temperature higher than
50 °C.
When used in hazardous environments corresponding to Class I, Division 2 or Class I,
Zone 2, the device must be installed in a cabinet or a suitable enclosure.
