Wireless considerations
Power up sequence
The Wireless Gateway should be installed and functioning properly before any wireless field devices are powered. Install the Black
Power Module, SmartPower™ Solutions model number 701PBKKF (part number 00753-9220-0001) into the Rosemount 702
Transmitter to power the device. Wireless devices should be powered up in order of proximity from the Gateway, beginning with
the closest device, then working outward from the Gateway. This results in a simpler and faster network installation. Enable Active
Advertising on the Gateway to ensure new devices are able to join the network faster. For more information see the Emerson™
Wireless 1420 Gateway Reference Manual.
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.
Figure 2: Antenna Position
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 Rosemount 702 Transmitter are
threaded ½–14 NPT.

High gain, remote antenna (optional)
The high gain, remote antenna options provide flexibility for mounting the device based on wireless connectivity, lightning
protection, and current work practices.
Figure 7: Rosemount 702 Transmitter with High Gain, Remote Antenna
Install the high gain, remote antenna (WN option)
Find a location where the remote antenna has optimal wireless performance. Ideally this will be 15–25 ft. (4.6–7.6 m) above the
ground or 6 ft. (2 m) above obstructions or major infrastructure.
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.
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 701 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 8 on page 7 for details on how to apply coaxial sealant.

6. Ensure the mounting mast and lightning arrestor are grounded according to local/national electrical code.
Any spare lengths of coaxial cable should be placed in 12-in. (0.3 m) coils.
Device network configuration
In order to communicate with the Smart Wireless Gateway, and ultimately the host system, the transmitter must be configured to
communicate with the wireless network. This step is the wireless equivalent of connecting wires from a transmitter to the
information system. Using a Field Communicator or AMS Wireless Configurator, enter the Network ID and Join Key so they match
the Network ID and Join Key of the Gateway and other devices in the network. If the Network ID and Join Key do not match that of
the Gateway, the Rosemount 702 Transmitter will not communicate with the network. The Network ID and Join Key may be
obtained from the Smart Wireless Gateway on the Setup Network Settings page on the web interface, shown in Figure 9 on page
7.
