WARNING
When installing remote mount antennas for the transmitter, always use
established safety procedures to avoid falling or contact with high-power
electrical lines.
Install remote antenna components for the transmitter in compliance with
local and national electrical codes and use best practices for lightning
protection.
Before installing, consult with the local area electrical inspector, electrical
officer, and work area supervisor.
The transmitter remote antenna option is specifically engineered to provide
installation flexibility while optimizing wireless performance and local
spectrum approvals. To maintain wireless performance and avoid non-
compliance with spectrum regulations, do not change the length of cable or
the antenna type.
If the supplied remote mount antenna kit is not installed per these
instructions, Emerson is not responsible for wireless performance or non-
compliance with spectrum regulations.
Procedure
1. Mount the antenna on a 1.5 to 2-in. pipe mast using the supplied
mounting equipment.
2. Connect the lightning arrestor directly to the top of the Rosemount
Transmitter.
3. Install the grounding lug, lock washer, and nut on top of lightning
arrestor.
4. Connect the antenna to the lightning arrestor using the supplied
LMR-400 coaxial cable ensuring the drip loop is not closer than 1 ft.
(0.3 m) from the lightning arrestor.
5. Use the coaxial sealant to seal each connection between the wireless
field device, lightning arrestor, cable, and antenna.
Note
The remote mount antenna kit includes coaxial sealant for
weatherproofing the cable connections for the lightning arrestor,
antenna, and Rosemount 702 Transmitter. Coaxial sealant must be
applied to guarantee performance of the wireless field network. See
Figure 3-4 for details on how to apply coaxial sealant.
