Use the following techniques to properly ground the transmitter case:

Transmitter Case

Always ground the transmitter case in accordance with national and local electrical codes. The most effective transmitter case grounding method is a direct connection to earth ground with minimal impedance. Methods for grounding the transmitter case include:

•Internal Ground Connection: The Internal Ground Connection screw

is inside the FIELD TERMINALS side of the electronics housing. This screw is identified by a ground symbol ( ). The ground connection screw is standard on all Rosemount 2051 transmitters. Refer to Figure 2-16.

•External Ground Assembly: This assembly is included with the optional transient protection terminal block (Option Code T1), and it is included with various hazardous location certifications. The External Ground Assembly can also be ordered with the transmitter (Option Code V5), or as a spare part. See “Spare Parts” on page A-25. Refer to Figure 2-17 for location of the External Ground Screw.
