2.6.4 Cable gland
If you are using cable glands instead of conduit, follow the cable gland manufacturer’s instructions
for preparation and make the connections in a conventional manner in accordance with local or plant
electrical codes. Be sure to properly seal unused ports to prevent moisture or other contamination
from entering the terminal block compartment of the electronics housing.
2.6.5 Grounding the transmitter case
The transmitter case should always be grounded in accordance with national and local electrical
codes. The most effective transmitter case grounding method is 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 ( ), and is standard on all Rosemount 8600D transmitters.
External Ground Assembly: This assembly is included with the optional transient
protection terminal block (Option Code T1). The External Ground Assembly can also be
ordered with the transmitter (Option Code V5) and is automatically included with
certain hazardous area approvals.
Note
Grounding the transmitter case using the threaded conduit connection may not provide a
sufficient ground. The transient protection terminal block (Option Code T1) does not provide
transient protection unless the transmitter case is properly grounded. See “Transient Terminal
Block” on page 27 for transient terminal block grounding. Use the above guidelines to ground
the transmitter case. Do not run the transient protection ground wire with signal wiring as the
ground wire may carry excessive current if a lightning strike occurs.
