For pressurized vessels, seal the flanged or
threaded process connection to prevent leakage.

Do not use the sensor base as a handle to
tighten the process connection.

Use suitable mounting bolts to mount a flanged
probe on a flanged process connection.

Proper grounding is imperative for correct
operation of the unit.

The unit can be grounded two ways. If
the tank is metallic, grounding is provided
by the tank. If the tank is not metallic, or
does not adequately make contact with
the sensor, a separate ground wire must
be provided by the customer. Run ground
wiring through the conduit and into the
electronics housing. Attach the ground
wire per

.

Open Sump or Basin
Do not suspend the unit by rigid conduit
installed in the electrical hub. When installing
the unit over an open sump or basin, use a
suitable bracket to support the instrument.

Condensation build-up inside the electronics
housing may damage the sensitive circuitry.
To prevent the ingress of moisture, use drip
loops or conduit runs which slope down from
the enclosure. (See

)

Bracket

Ensure that wiring conforms to all applicable local and national electrical codes and install
unit(s) according to relevant national and local safety codes.

Electrical power must be disconnected from explosion proof models before
the cover is removed. Failure to do so could result in severe personal injury
or substantial property damage.
