Connect the sensor to the module

W A R N I N G
Potential Electrocution Hazard. Always disconnect power to the
instrument when making electrical connections.
W A R N I N G
Electrocution Hazard. High voltage wiring for the controller is conducted behind the
high voltage barrier in the controller enclosure. The barrier must remain in place
except when installing modules, or when a qualified installation technician is wiring
for power, relays or analog and network cards.
N O T I C E
Potential Instrument Damage. Delicate internal electronic components
can be damaged by static electricity, resulting in degraded performance
or eventual failure.
To install the module and connect the sensor, refer to the illustrated steps
and Table 3. Be sure to connect the clear wire with the black band from
the contacting conductivity sensors to the controller chassis.
Note: If the sensor cable is not long enough to reach the controller, an interconnect
cable and junction box are required to extend the distance. The T-factor should then
be adjusted (Adjust the T-factor for non-standard cable lengths
