Standard Installation Materials
Recommended standard materials should be selected and installed per all applicable local, state and federal codes
governing the installation of this product and its associated systems. Please see the corresponding console / module
wiring section or the associated devices section of this manual for complete installation details.
Cables Required for Liquid Level Probes, and 4-20 mA Sensors
Use cables and wires compliant with national and local codes. Franklin Fueling Systems recommends using the types of
cable shown below up to a recommended length of:
• Belden No. 87760 87760 (0.15" or 3.048 mm OD) to 260 feet (80 m)
• Belden No. 87761* (0.12" or 3.048 mm OD) to 400 feet (120 m)
• Belden No. 89182* (0.31" or 7.874 mm OD) to 1500 feet (450 m)
Note: An asterisk (*) denotes a cable that may be ordered from Franklin Fueling Systems.
Note: Conductors of different intrinsically safe (IS) circuits may be run together within the same conduit, and, when they
do, they should have at least .01 inches (.25 mm) of insulation.
Cable or Wire for 2-Wire or 3-Wire Sensors
2-wire or 3-wire sensor wire (type THHN, TFFN, or THWN, gas and oil resistant, 18 AWG minimum, 1500 feet max. wire
run length) can be used when enclosed within rigid metal conduit from the sensor to the console.
Leak detection sensor cable is required when NOT run through rigid metal conduit. Refer to the Direct Burial Cable –
Installation Manual (P/N 000-1041) for further information. See below for cable types and descriptions:
Alpha 58411 (Franklin Fueling Systems P/N 600-0062)
Two conductor cable for standard, 2 conductor leak detection sensors (0.114 inch (2.9 mm) O.D.)
Wire required for the TS-550/5000 evo Console
• 3 conductors: Power – 14 GA to 12 GA Max. – Black, White, and Green
• 1 conductors: Safety Ground – 12 AWG Green (2 may be required in some locations)
• As required conductors: Accessories – Type THHN, TFFN, or THWN, 18 AWG minimum
Circuit Breaker
20 Amp — providing power only for the TS-550/5000evo console, one required per console
Note: Do not run other non-intrinsically safe wiring within the I.S. pull box.
Weatherproof Junction Boxes
Minimum 16 cubic inch (406.4 cubic mm) weatherproof junction box, cover, and cover gasket for the manholes of:
liquid level probes and leak detection sensors. Also use ¾ to ½ inch (12.7 mm to 19.05 mm) bushings for probe/sensor
compression ttings.
Use a weatherproof metal pull box for combining several circuits that will run into the TS-550 / 5000 evo console through
one or more conduits. Use a separate weatherproof metal pull box to combine intrinsically safe (IS) liquid level probe and
leak detection sensor wiring. Do not run other non-intrinsically safe wiring within the IS pull box. Run ½ or ¾ inch (12.7
mm or 19.05 mm) IS probe or sensor conduit from the manholes to the IS pull box, and then run up to four ½ or ¾ inch
(12.7 mm or 19.05 mm) conduits to the console’s IS conduit knockouts.
Conduit
Rigid metal conduit (RMC) - male NPT threaded: use ½ or ¾ inch (12.7 mm or 19.05 mm) for IS probe and sensor wiring
to the console (from the manholes, use ½ or ¾ inch conduit), and use ½ or ¾ inch (12.7 mm or 19.05 mm) for non-
intrinsically safe accessories and power wiring.
Use conduit hardware that is appropriate for the installation and meets local, state and federal requirements.
Splice Connector Kits Must Be Used — Warranty Requirement
Use the Franklin Fueling Systems-approved, moisture-resistant, no-strip splice connectors for liquid level probe and leak
detection sensor wires. You may order the TSP-KW30, which contains 30 of the Franklin Fueling Systems-approved,
moisture-resistant connectors.
Using moisture resistant splice connectors will:
• Reduce/eliminate corrosion of the wire connections from repeated exposure to water condensation, which causes
eventual signal loss and system failure.
• Reduce/eliminate equipment damage from water ooding around the connectors, which causes short-circuit damage.
