Working on Electronic and Electrical Components
Explosive vapors or liquids are present in and around the fuel dispensing equipment, which
can be ignited by open flames, electrical arcs, or static electricity discharges.
A potential shock hazard exists when working with this equipment. Electricity discharges can
cause injury and damage sensitive electronic components. Follow all precautions and
requirements.
WARNING
Read and follow all precautions and requirements before performing any
inspection and/or maintenance in a potentially dangerous environment of
flammable fuels, vapors, and high voltage.
Fire, explosion or electrical shock could result in severe injury or death if safety
procedures are not strictly followed.
Do not smoke and prevent open flames in the pump area.
Promptly clean up spills or debris in the pump area.
Preparing for Service
To prepare for service, perform the following:
• Barricade the working area.
• Shut off all power from units with electronic components to be serviced. Shut off power
from associated connected devices, for example, STP. Multiple disconnects may be
required.
• Use extreme caution during any observation or testing procedure that requires power to be
applied to the unit.
• To prevent damage from Electrostatic Discharge (ESD) to electronic components or
ignition of flammable fuels or vapors, follow all precautions and requirements.
Preventing ESD
Use Integrated Circuit (IC) extractor
Ground Wrist Strap is required
WARNING
!
PCAs and Integrated Circuits (ICs) are sensitive to ESD. ESD can damage electronic parts.
