Wiring/Miscellaneous For TLS-IB Consoles W/RS-232 & With & W/O IFSF) Connecting Power Wiring to TLS-IB4-6Connecting Power Wiring to TLS-IB1. Pull four wires between the power panel and the TLS-IB; three #14 AWG or larger diameter color-codedwires for AC line (L), AC neutral (N) and chassis ground; and one #12 AWG (4 mm2 cross-sectional area)green and yellow wire for barrier ground.For international applications, console power should come from a dedicated circuit via a fused, switched, neonindication spur within one metre of the console position. From an independent 24 hour supply at the distribu-tion panel, run three 2.5 mm 2 (minimum) standard colour coded wires, live, neutral and earth, to the fusedspur. Run three similar wires from the spur to the console location. Run one 4mm 2 wire, colour coded green/yellow, from the earth bus bar at the distribution panel direct to the console location. Leave at least 1 metre offree cable for connection to the console.Use an ohmmeter to check the electrical resistance between the console’s metal case andthe earthing ground wire’s connection at the “known good earth ground” (copper rod driveninto ground, etc.). It should read less than 1 ohm.2. Open the door of the TLS-IB and connect the four power/ground wires as shown in [Figure 4-4]. Do notconnect the power wires to breaker panel at this time.WARNINGThe TLS-IB contains voltages which can be lethal. It is connected to devicesthat must be intrinsically safe.FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS AND SAFETYPRECAUTIONS COULD CAUSE DAMAGE TO PROPERTY, ENVIRONMENT,RESULTING IN SERIOUS INJURY OR DEATH.1. Turn power Off at the circuit breaker connecting the power supply wires.2. Attach conduit from the power panel to the TLS-IB Power Areaknockouts only (1 on top and 2 on bottom, ref.
