Fig. 29 Wiring connections
Notes:
-
Submersible transducer cables are larger diameter. Each cable requires a separate conduit hole.
The standard yellow cable and high temperature cables are small enough to use a single cable
gland with a 2-hole grommet.
-
Transducer cables have two wire-color combinations. For the blue and white combination, the
blue wire is positive (+) and the white wire is negative (-). For the red and black combination,
the red wire is positive (+) and the black wire is negative (-). The transducer wires are labeled to
indicate which pair is upstream or downstream.
