Introduction

Every person working with Veeder–Root equipment is expected to take every safety
precaution possible in the installation of the TLS Systems.
Contractors must ensure that supervisory personnel on the installation site are aware of their presence and
requirements, especially the provision of safe working areas and isolation from AC electrical power.
It is the contractor's responsibility to comply with the instructions and warnings found in this manual.
INTRINSIC SAFETY
The design of Veeder–Root products limits the power in the wiring to the sensors and keeps this wiring physically
separated from any other. It is the responsibility of the contractor to maintain the effectiveness of these safety
features by preparing the installation site in accordance with the instructions and warnings which follow. Failure to
do so could create danger to life and property. Only those products contained in the system descriptive
documents are certified by Veeder-Root. The safe installation and placing of equipment into service that is not
contained on the system descriptive documents is the sole responsibility of the installer, end user and local
authority having jurisdiction. All installations must comply with all local, national and international codes.
Circuitry within the console barrier forms an intrinsically safe, energy limited system. This system makes the
sensors suitable for use in hazardous locations. Sensor wiring is intrinsically safe only when connected to the TLS
console. All sensor wiring must be contained in dedicated ducts.
Substitution of specified components may impair intrinsic safety.

IMPORTANT SAFETY INFORMATION
This section introduces the hazards and safety precautions associated with installing,
inspecting, maintaining or servicing this product. Before performing any task on this
WARNING
This product operates
in a potentially dangerous environment of a gasoline/
diesel filling station in which exist flammable fuels, vapors, and high voltage or
pressures
.
FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS AND SAFETY
PRECAUTIONS COULD CAUSE DAMAGE TO PROPERTY, ENVIRONMENT,
RESULTING IN SERIOUS INJURY OR DEATH.
1. All installation work must comply with the latest issue of the National
Electrical Code (NFPA 70), PEI/RP1100 Recommended Practices For The
Storage And Dispensing Of Diesel Exhaust Fluid (DEF), and any European,
national, state, and local code requirements that apply.
2. Explosion could occur if other wires share ducts with intrinsically safe probe
or sensor wiring. Ducting from probes and sensors must not contain any
other wiring circuits.
3. Turn off, tag, and lockout power to the DEF pump before connecting or
servicing it.
4. Do not step on DEF pump when entering or leaving the sump.
5. Before installing pipe threads apply an adequate amount of fresh DEF
