Sensor leads

If the sensor is installed in a high-voltage environment and a fault condition or installation

error occurs, the sensor leads and transmitter terminals could carry lethal voltages. Use

extreme caution when making contact with the leads and terminals.

Use the following steps to wire the sensor and supply power to the transmitter:

Bench top configuration consists of testing the transmitter and verifying transmitter

configuration data. The Rosemount 648 Wireless must be configured before installation,

which may be performed either directly or remotely. Direct configuration can be performed

using a Field Communicator, AMS Device Manager, AMS Wireless Configurator, or any

WirelessHART

Manager, AMS Wireless Configurator, or the Smart Wireless Gateway.

The power module must be installed to provide power to the Rosemount 648 Wireless for

configuration. To communicate to the transmitter, begin by removing the power

module-side housing cover, indicated as "Field terminals" by text located on the side of the

device. This will expose the terminal block and HART

labeled "COMM". Connect the power module to supply power for configuration. See
