TLS Magnetostrictive Probes International Installation Guide Field Wiring20Field WiringPROBE TO TLS CONSOLEPull appropriate cable from the each probe location to the TLS console.Explosion could occur if other, non–intrinsically safe wires share TLS intrinsically safe wire conduits or wiringtroughs. Conduits and wiring troughs from probes and sensors to the console must not contain any other wires.At least 2 metres of free cable must be left for connection at both the TLS console and the probe locations.Ensure that all cables are correctly identified. All probe field wiring must be legibly and permanently labelled withthe tank number.Failure to correctly mark probe field wiring may lead to re-work, delays in system installation and additionalcharges.MAXIMUM CABLE LENGTHSA maximum of 305 metres of cable length per probe must be observed.SPLICING PROBE FIELD WIRING1. Insert the probe cable through the top of each riser cap and through the Hummel cable leader bushing.2. Cut the soft vinyl epoxy enclosure end cap entrance holes to accommodate each cable diameter. Keep thehole sizes to a minimum. Insert about 127mm of each cable through the openings [Figure 19]. Remove 76mmof the outer jacket from each cable. Trim the insulation from the conductors.Figure 19.
