CAUTION
•
Installation of the transient protection terminal block does not provide
transient protection unless the Rosemount 2051HT case is properly
grounded.
•
Do not run signal wiring in conduit or open trays with power wiring, or
near heavy electrical equipment.
•
Do not connect the powered signal wiring to the test terminals. Power
could damage the test diode in the terminal block.
Use the following steps to wire the transmitter:
Procedure
1. Remove the housing cover on the FIELD TERMINALS side.
2. Connect the positive lead to the “+” terminal (PWR/COMM) and the
negative lead to the “–” terminal.
3. Ensure full contact with Terminal Block screw and washer. When using
a direct wiring method, wrap wire clockwise to ensure it is in place
when tightening the terminal block screw.
Note
The use of a pin or a ferrule wire terminal is not recommended as the
connection may be more susceptible to loosening over time or under
vibration
4. Ground housing to fulfill local grounding regulations.
5. Ensure proper grounding. It is important the instrument cable shield
be:
•
Trimmed close and insulated from touching the transmitter
housing
•
Connected to the next shield if cable is routed through a junction
box
•
Connected to a good earth ground at the power supply end
6. If transient protection is needed, refer to section “
Grounding for
transient terminal block
” for grounding instructions.
7. Plug and seal unused conduit connections.
8. Reattach the transmitter covers. It is recommended that the cover be
tightened until there is no gap between the cover and the housing.
