2.5.4 Connect the power module for WirelessHART transmitter

The power module should not be installed on any wireless device until the Gateway is installed and functioning properly. This transmitter uses the black power module (order model number 701PBKKF). 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 new devices join the network faster. For more information, see the Emerson Wireless Gateway 1420 Reference Manual
