DANGER
:
DO NOT connect sensor cable to power lines. Serious injury may result.
Take care to route sensor cable away from AC power lines, adjustable frequency drives, motors,
or other noisy electrical signal lines. Do not run signal lines in the same conduit as AC power
lines. Run signal cable in dedicated metal conduit if possible. For optimum electrical noise
protection, run an earth ground wire to the ground terminal in the transmitter.
