NOTICE The Rosemount 702 and all other wireless devices should be installed only after the Smart Wireless Gateway has been installed and is functioning properly. Wireless devices should also be powered up in order of proximity from the Smart Wireless Gateway, beginning with the closest.
June 2010 CONSIDERATIONS General Switches produce either an open or closed signal. By using simple HART configuration, the Rosemount 702 converts the switch signal to a wireless-enabled signal. Wireless Considerations Power Up Sequence The power module should not be installed on any wireless device until the Smart Wireless Gateway (“Gateway”) is installed and functioning properly.

Conduit Entries Conduit Entry Conduit Entry Field Communicator Connections The Power Module needs to be connected for the Field Communicator to interface with the 702. Figure 1-3. Field Communicator Connections P/N 00753-9200-0020 COMM Mechanical Location When choosing an installation location and position, take into account access to the transmitter.
June 2010 Electrical Power Module The Rosemount 702 WirelessHART™ transmitter is self-powered. The included power module contains two “C” size primary lithium/thionyl chloride batteries. Each battery contains approximately 2.5 grams of lithium, for a total of 5 grams in each pack. Under normal conditions, the battery materials are self-contained and are not reactive as long as the batteries and the power module are maintained.
Reference Manual 00809-0200-4702, Rev BA Rosemount 702 June 2010 Example The transmitter specification limit is 185 °F (85 °C). If the ambient temperature is 131 °F (55 °C) and the maximum process temperature to be measured is 1500 °F(815 °C), the maximum permissible connection head temperature rise is the transmitter specification limit minus the ambient temperature (moves 185 °F to 131°F [85 to 55 °C]), or 86 °F (30°C).

MOUNTING The Rosemount 702 can be installed in one of two configurations: Direct Mount: The switch is connected directly to the 702’s housing’s conduit entry. For installation instructions see Direct Mount on page 3-2. Remote Mount: The switch is mounted separate from the 702 housing, then connected to the 702 via conduit.

Rosemount 702 June 2010 GROUND THE The Rosemount 702 operates with the housing grounded or floating. Floating systems, however, can cause extra noise that may affect many types of TRANSMITTER readout devices. If the signal appears noisy or erratic, grounding at a single point may solve the problem.
• Use extreme caution when making contact with the leads and terminals. NOTE The Rosemount 702 and all other wireless devices should be installed only after the Gateway has been installed and is functioning properly. Wireless devices should be powered up in order of proximity from the Gateway, beginning with the device closest to the Gateway.
