Introduction
1.4.1 Functions of the transmitter
Switches produce either an open or closed signal. By using simple HART configuration, the 702
transmitter converts the switch signal to a wireless-enabled signal.
1.4.2 Wireless Considerations
Power Up Sequence
The Smart 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 702 transmitter to power the
device. 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 that new devices join the network faster. For more
information see the Smart Wireless Gateway Manual (Document Number 00809-0200-4420).
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.

Preparing (or sealing) the conduit entries
Upon installation, ensure that each conduit entry is either sealed with a conduit plug with
appropriate thread sealant, or has an installed conduit fitting or cable gland with appropriate
thread sealant.
