3 Electrical Installation & Wiring
Electrical Installation & Wiring Sequence:
Basic Installation & Wiring
Follow the instructions here to wire the LS300 Auto-Learn console, the
LSU300 Transducers from each STP containment sump, the Dispenser
Hook Inputs, and Console Power Input. (see Figure P-1 & Figure 3-1).
Ask the service tech to do “mechanical - pump/dispenser” work if
appropriate.
1.) All cables from the LSU300 transducer to the LS300 console must be installed in metal conduit in
countries requiring CE compliance. Power and communication wires do not need metal conduit
unless it is required by local code.
WARNING Avoid personnel injury or property damage: ALWAYS secure the hazardous work area
from moving vehicles. This equipment is usually mounted underground, therefore, reduced visibility
puts service personnel working on this equipment in danger from moving vehicles entering the work
area. Use Safety Cones, Barricades, Warning Signs, and Safety Tape, and block access with
Barricades / service vehicles to the work area to avoid injury or property damage.
2.) At the electrical power panel: locked-out & Tag POWER OFF for the STP’s, Pump Controllers, and
Dispensers.
ELECTRICAL DANGER Hook inputs are 120/240 Vac. Disconnect all high voltage sources before
accessing internal electronics
DANGER Electronic line leak detectors start submersible pumps automatically to run leak-tests at
full line pressure. Automatic pump starts occur between periods of product dispensing when there is
no product being dispensed. BEFORE performing any installation or service (such as replacing
fuel-filters) – tag and lock-out all electrical power sources to the submersible pump(s), pump
controllers, and dispensers and relieve fuel-line pressure. Failure to turn off power and
relieve fuel-line pressure before work is started can result in: pressurized fuel spills (an
environmental hazard associated with costly cleanups), and fire or explosion hazard that may
result in injury or death.
3.) If not done during Mechanical Installation, chapter 2, Run 3 conductor shielded cable from each
Explosion proof/Weatherproof Junction Box in the STP sump where the LSU300 Transducer is
installed, to the LS300 console for Transducer wiring leaving about an 8 inch (203 mm) service loop
(Figure 3-2 & 3-3). Label/Mark each cable jacket with the Tank # / LSU300 Transducer number.
