Connections and Routing...
All of the standard sensors (water quality and meteorological) have pre-wired waterproof
connectors on the bottom of the 6200 DCP. See Figure 4.1 to locate specific connector sites. In
addition, there are two holes (0.875 in or 22 mm) in the bottom of the enclosure for use with
conduit fittings or feed-through glands. These holes are plugged with NEMA 4X rated seals.
One of the two holes should be used for power lines in the options involving AC or solar power.
The second hole may be used for a phone line, direct serial cable, or for non-standard sensors
that must be wired to the expansion terminal block inside the enclosure. We do not recommend
that you route power cables and sensor cables through the same conduit hole.
Grounding...
Although there are several options related to powering your 6200 DCP field station, you should
properly ground the 6200 DCP. Refer to Figure 4.1 to locate the earth ground connector. We
recommend #6 standard copper wire connected to a 6’ grounding rod to earth ground your DCP,
however refer to your local wiring codes to insure proper grounding installation.

In addition to the ground connector, notice the four MS waterproof connectors for the sensors,
including the 6-Series Sonde connector. If you are installing sondes at your field station, note
that the sondes are powered by the 6200 DCP and are operated with a “floating” ground. This
requires that the sonde not be individually grounded. Grounding the sonde individually will
cause a “ground loop”, i.e., one conductor of the sonde output grounded common to both the
sonde and the DCP circuitry. Grounding the sonde will cause significant performance problems
with the sensors and will likely result in erroneous readings.
CAUTION!
Do not ground the sonde body.
