4. Tank-Probe or Smart Sensor wires that use a prepared Belden or Alpha cable must go through NPT
bushings into a weatherproof junction box. Bushings must be used in all junction boxes.
5. The cable must go through rigid steel conduit from the junction box directly to the I.S. barrier.
6. Put a label on each cable and conductor wire to identify its connection.
CAUTION: The console must have a dedicated power circuit and must be
on the same phase as all other OPW equipment.
Only OPW probe cables and sensor wiring can be in the same conduit that
goes to the I.S. barriers.
NOTICE: Incorrect cables, wiring, or conduit can cause electronic noise interference with
probe/sensor measurements. This can cause measurement indications at the console that
can show as a hardware error. The warranty is voided if incorrect cables, wiring and/or
conduit are installed. The ground wire must be correctly installed for the noise-filtering
circuitry to operate correctly. Thus, the conduit must not be used for operation of the
ground.
