(22 - 18 AWG)
Do not use a coaxial transducer cable extension with the
EnviroRanger because of electrical noise.
Relay output

Transducers
Warning:
Hazardous voltage present on transducer terminals during
operation.
Run the transducer cable in a grounded metal conduit, separate from other
wiring, (except TS-3 temperature sensor wiring, if applicable).
Notes:
•
Do not use coaxial cable because of electrical noise.
•
Do not connect the shield and white transducer wires.
