Wireless considerations

1.1 Power up sequence
The Rosemount
installed only after the Wireless Gateway ("Gateway") has been installed and
is functioning properly. Wireless devices should also be powered up in order
of proximity from the Gateway, beginning with the closest. This will result in
a simpler and faster network installation. Enable active advertising on the
Gateway to ensure new devices join the network faster. For more
information, see the Wireless Gateway
1.2 Antenna position
The antenna should be positioned vertically, either straight up or straight
down, and it should be approximately 3 ft. (1 m) from any large structure,
building, or conductive surface to allow for clear communication to other
devices.

1.3 Conduit entry
Upon installation, ensure each conduit entry is either sealed with a conduit
plug using approved thread sealant, or has an installed conduit fitting or
cable gland with appropriate threaded sealant. Note the conduit entries on
the Emerson 781 Field Link are threaded ½–14 NPT.
