Before You Begin

• 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 

requirements.

• 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 

from a Class I, Division 1 or 2 hazardous area into a non-hazardous area. 

• 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.

• When installing on a vent stack, customer supplied pipe and pipe fittings shall be standard full-weight (ASTM 

Schedule 40) wrought iron or steel.

• Customer supplied copper tubing shall be soft tempered, 1/4-inch O.D., with a minimum wall thickness of 

0.0265 inches.

• Pipe threads shall be in accordance with the Standard for Pipe Threads, General Purpose (Inch) ANSI/ASME 

B1.20.1-1983.
