Network design best practices

When mounting the device, recommended practices should be considered to achieve the best wireless performance. See Appendix D: Network design best practices for more information 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 Figure 1-4for 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 easy power module replacement.

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).
