Transmitter case grounding
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 2088 transmitters.
Refer to
Figure 4-9 on page 48
.
External ground connection: The external ground connection is located on the exterior
of the transmitter housing. Refer to
Figure on page 48
. This connection is only available
with option T1.
