• Comply with all recommended safety practices identified by OSHA (Occupational Safety and Health
Administration) and your employer.
• Review and comply with all the safety warnings in the installation manuals and any other national, State or Local

• When direct wiring to the TLS console, a 2-conductor, 18 AWG shielded cable must be installed in intrinsically
safe conduit from the dispenser or from the vapor vent stack to the TLS console. The cable length between the
console and sensor must not exceed the distance stated in the appropriate console’s site prep manual. Conduit
for direct-wired installations must be properly sealed in accordance with the latest National Electric Code
(NFPA 70) and the Code for Motor Fuel Dispensing Facilities and Repair Garages (NFPA 30A) since they pass

• Conductors of different intrinsically safe circuits run in the same cable/conduit must have at least 0.01 inch
(0.25 mm) of insulation.
• For all connections requiring sealant, use only UL classified yellow Gas/TFE plumbing tape.
• Intrinsically safe devices must be installed in accordance with Article 504 of the National Electrical Code, ANSI/
NFPA 70, for installation in the United States, or Section 18 of the Canadian Electrical Code for installations in
Canada.
