ATI Q46D Dissolved Oxygen System Part 4 – Electrical Installation

4.6 Direct Sensor Connection
The sensor cable can be routed into the enclosure through one of cord-grips supplied with the
unit. Routing sensor wiring through conduit is only recommended if a junction box is to be used.
Some loose cable is needed near the installation point so that the sensor can be inserted and
removed easily from the flowcell.
Cord-grips used for sealing the cable should be snugly tightened after electrical connections have
been made to prevent moisture incursion. When stripping cables, leave adequate length for
connections in the analyzer enclosure as shown below. The standard 25 ft. sensor cable
normally supplied with the system is already stripped and ready for wiring. This cable can be cut
to a shorter length if desired to remove extra cable in a given installation. Do not cut the cable so
short as to make installation and removal of the sensor difficult.
