2.1 General wiring guidelines
Figures in
396P sensor to various transmitters.
To determine which wiring diagram to use, locate the model number of the
sensor to be installed.
If you need to extend the cable, use a high quality eleven conductor double-
shielded instrument cable (part number 9200273) available from Emerson.
Note
If the cable is too long, loop up the excess cable. If you need to shorten the
cable, cut and terminate each conductor neatly and make sure that the
overall (outermost) drain wire is not shorted out with either of the two inner
drain wires (shields).
Run signal cable in a dedicated conduit (preferably an earth grounded
metallic conduit) and keep it away from AC power lines. For your
convenience, Emerson has furnished a wire nut kit (in a plastic bag wrapped
around the cable).
CAUTION
For maximum electromagnetic interference/radio frequency interference
(EMI/RFI) protection when wiring from the sensor to the junction box,
connect the outer braid of the sensor to the outer braided shield of the
extension cable. Terminate the outer braid of the extension cable to the
instrument at earth ground or use an appropriate metal cable gland fitting
to provide a secure connection to the instrument cable.
2.2 Wiring diagrams

shielded cable.
WARNING
Serious injury may result.
