The Smart Wireless Gateway (Gateway) should be installed and functioning properly before any wireless
devices are powered. Install the power module, SmartPower™ Solutions, model number 701PGN Green
Power Module, into the Rosemount 708 Transmitter to power the device. This results in a simpler and
faster network configuration. Enabling Active Advertising on the Gateway ensures new devices are able
to join the network faster. For more information, see the Smart Wireless Gateway Reference Manual.
Figure 3-1. Power Module Installation
Antenna position
The antenna is internal to the acoustic transmitter. To achieve optimal range, position the transmitter
with the waveguide horizontal and the power module closest to the ground as shown in Figure 3-2.
Good connectivity can also be achieved in other orientations. The antenna should also be approximately
1 m (3 ft.) from any large structure, building, or conductive surface to allow for clear communication to
other devices. Refer to best practices for additional information on optimal mounting locations of device.

Mounting installation considerations
1. Inspect mounting bands periodically and re-tighten if necessary. Some loosening may occur after
initial installation due to thermal expansion/contraction.
2. Ensure the waveguide is in direct contact with the pipe.
3. Insulate process piping to minimize ambient temperature effects (see Figure 3-8). Insulation
thickness over the top of the waveguide foot should not exceed 2.54 cm (1-in).
4. For best results, mount the transmitter within 15.24 cm (6 in.) of the equipment being monitored.
5. The stainless steel mounting bands could be affected by stress corrosion and potentially fail when in
the presence of chlorides.
6. The transmitter should be installed such that steam or other high temperature fluids do not directly
impinge the housing of the device.
7. If installing the device on a steam trap, the device should be installed on the upstream side of the
trap.
3.3
Mounting
For high temperature mounting, see Mounting in a high temperature application .
1. Locate the Rosemount 708 Transmitter on a horizontal section of piping as close as possible to the
equipment to be monitored. Align the waveguide of the transmitter as shown in Figure 3-4
2. Ensure the mounting location is free of foreign matter and corrosion to ensure good contact between
the piping and waveguide.
3. Tighten each clamp to 10.2 N-m (90 in-lb). Trim the excess clamp band material to prevent unwanted
acoustic noise.
4. If commissioning the device, install the power module (see Figure 3-5 on page 12).
5. Ensure the power module cover is fully tightened to prevent moisture ingress. The lip of the polymer
power module cover should be in contact with the surface of the polymer enclosure to ensure a
proper seal. Do not over tighten.

5.2
Operation
The Rosemount™ 708 Acoustic Wireless Transmitter measures ultrasonic acoustic energy and waveguide
temperature. The acoustic level is reported in 'counts,' which are a relative indication of the magnitude.
The sensor used in the Rosemount 708 Transmitter is sensitive to a broad range of frequencies to work in
many different applications. The acoustic measurement or “count” in the transmitter is an average of the
broad range of frequencies. No additional signal processing is performed to isolate specific frequencies.
This count information is used to determine the state of a steam trap, pressure relief valve, or other
mechanical system. The device works similarly to a discrete device, looking for a large change in noise
level occurs during a leak or release. In the case of steam traps, SteamLogic™ software calculates the
steam trap state based on the acoustic and temperature information published by the Rosemount 708
Transmitter. See SteamLogic Reference Manual for further information.

Use caution when handling the power module; it may be damaged if dropped from heights in exceeding
6.1 meters (20 feet).
Battery hazards remain when cells are discharged.
Environmental considerations
As with any battery, local environmental rules and regulations should be consulted to properly manage
spent batteries. If no specific requirements exist, recycling through a qualified recycler is encouraged.
Consult the materials safety data sheet for battery-specific information.
Shipping considerations
The unit was shipped without the power module installed. Remove the power module prior to shipping.
Each power module contains one “D” size primary lithium battery. Primary lithium batteries are
regulated in transportation by the U. S. Department of Transportation, and are also covered by the
International Air Transport Association (IATA), International Civil Aviation Organization (CAO), and
European Ground Transportation of Dangerous Goods (ARD). It is the shipper’s responsibility to ensure
compliance with these or any other local requirements. Consult current regulations and requirements
before shipping.

Appendix C
Recommended Practices
Follow all recommended practices to ensure highest data reliability. Deviation from these best practices
may require device repeaters in the network to maintain 99 percent data reliability. Follow these
guidelines to achieve the best possible Smart Wireless Network:
1. Scope each wireless network field to a single process unit.
2. Minimize the number of hops to the Gateway to reduce latency. Contain a minimum of five wireless
instruments within effective range of the Smart Wireless Gateway.
3. Have at least three devices with potential communication paths. For stronger performance, increase
the required number of wireless neighbor devices to four or five. This increases the number of
potential paths and optimizes network performance.
4. Have 25 percent of wireless instruments in the network within range of Smart Wireless Gateway.
Other enhancing modifications include creating a higher percentage of devices within effective range
of the Gateway to 35 percent or more. This clusters more devices around the Gateway and ensures
fewer hops and more bandwidth available to WirelessHART® devices with fast scan rates.
5. Minimize the path distance from the Gateway. For better performance, the path is typically within
range of one or two hops. This will utilize path redundancy and create very short transit times.
6. Determine effective range by type of process unit and density of the infrastructure surrounding the
network.
C.1
Effective range
Heavy Obstruction: 100 ft. (30 m)–Typical heavy density plant environment; a truck or equipment
cannot be driven through this.
Medium Obstruction: 250 ft. (76 m)–Typical light process areas; lots of space between equipment and
infrastructure.
Light Obstruction: 500 ft. (152 m)–Typical of tank farms; despite tanks being big obstructions
themselves, lots of space between and above makes for good RF propagation.
Line of Sight: 750 ft. (230 m)–No obstructions between WirelessHART® devices and devices mounted a
minimum of 6 ft. (2 m) above ground or obstructions.
For examples and complete explanations, refer to the IEC62591 WirelessHART System Engineering
Guide.
