5 Conduit and Junction Boxes
Conduit Requirements
All wiring for the Tank Sentinel ® system must be installed within conduit.
Exceptions to this requirement (such as the Fax/Modem telephone
communications cables) are noted in this manual. Other exceptions may be
shown in other Tank Sentinel
® documentation, such as accessory manuals,
application bulletins, or addendum. Reference all documentation provided, and
your local codes.
Intrinsically Safe (I.S.) Probe and Sensor Conduit
The I.S. (Intrinsically Safe) liquid level probe cables and leak detection sensor
wiring must be completely enclosed in conduit, or as specified by your local
codes. Use 1/2” or 3/4” (12.7 mm or 19.1 mm) conduit from the weatherproof
junction box at the manhole, to an Intrinsically Safe weatherproof pull box, or
run 3/4” (19.1 mm) conduit directly to the console. This conduit must not contain
any other wiring other than the Intrinsically Safe probe or sensor wiring.
You may install a separate conduit for each probe and sensor, or you may use a
common conduit to carry the cables from several liquid level probes and leak
detection sensors – see Figure 5-1 on the last page of this chapter.
Intrinsically safe (I.S.) probe cable(s) and leak detection sensor
wires/cables may be run together within the same conduit.
I.S. Weatherproof Pull Box
The Intrinsically Safe, metal, weatherproof pull box must not contain any wiring
other than the I.S. probe or sensor wiring – see Figure 5-1 on the last page of this
chapter.
Epoxy “ Y “ Seal Fittings (EYS)
EYS fittings must be installed at the manhole and at the building. The EYS fittings
must be sealed with epoxy – see Figure 5-1 on the last page of this chapter.
Conduit Knockouts
Either three 1/2” – 3/4” (12.7 - 19.1 mm), or four 3/4” – 1” (19.1 - 25.4 mm)
dual-sized knockouts are provided at the console for intrinsically safe probe and
sensor connections from the weatherproof pull box, or junction boxes. As you
plan the location and number of conduits that you will install, consider the
number and diameter of the probe and sensor cables.
