Network design best practices

When mounting the device, recommended practices should be considered to achieve the best
wireless performance. See AppendixD: Network design best practices for more i nformation on
recommended practices.

Field communicator connections

The Power Module needs to be installed in the device for the Field Communicator to interface
with the Rosemount 2051. The Field Communicator connections are located on the Power
Module. To communicate to the transmitter, connect the Field Communicator to the COMM
port connections on the Power Module. This transmitter uses the Green Power Module; please
order model number 701PGNKF. Field communication with this device requires a HART-based
Field Communicator using the correct Rosemount 2051 Wireless DD. The Power Module is
keyed and can only be inserted in one orientation. Refer to Figure1-4 for instructions on
connecting the Field Communicator to the 2051.

Location

When choosing an installation location and position, take into account access to the power
module compartment for eas y power module repla cement.

Electronics cover

The electronics cover is tightened so that polymer contacts polymer. When removing the
electronics cover, ensure that there is no damage done to the o-ring. If damaged replace before
reattaching cover, ensuring polymer contacts polymer (i.e. no o-ring visible).

Power module

The Rosemount 2051 Wireless Pressure Transmitter is self-powered. The Power Module
contains a primary lithium-thionyl chloride battery (Green Power Module, model number
