Site Prep - International Installations Field Wiring2-8Field WiringPROBE TO TLS-IB LOCATION (LEVEL 1 INSTALLATIONS ONLY)Pull one two core, Probeflex cable from the TLS-IB location to each probe location.An explosion could occur if other, non–intrinsically safe wires share TLS intrinsicallysafe wire conduits or wiring troughs. Conduits and wiring troughs from probes andsensors 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-IB and the probelocations.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 rework, delays in system installationand additional charges.MAXIMUM CABLE LENGTHSA maximum of 305 metres of cable length per sensor or probe must be observed.DUCTING ENTRY TO TLS-IB LOCATIONConnection to the TLS-IB may only be made by a Veeder–Root authorised engineer.The cable route from the ducting entry to the TLS-IB must be clearly defined and all necessary preliminary workundertaken. All necessary holes must be drilled through walls, counters, etc.; cable trays fitted, ducting with drawcords installed and adequate access for the installation of the cable provided.Equipment Connected To The RS-232 PortAny equipment such as a pump controller or point–of–sale terminal connected to the RS-232 port must meet thefollowing criteria:• The equipment must have an EIA standard RS-232C or RS-232D communications protocol.• The equipment must NOT be installed over or in a hazardous location.The RS-232 Interface can be used for direct local attachment of terminals if the cable run is no more than 15metres. Veeder-Root do not guarantee proper equipment operation if RS-232 cable runs exceed 15 metres.RS-232 cable runs longer than 15 metres could result in data errors.Run cable from the peripheral equipment location to the system console location. At least 1 metre of free cablemust be left for subsequent connection at both ends.Core Colours Black, red, green, whiteNominal Outside Diameter 4.2 mmRecommended UK Supplier: RS Components Ltd., Stock number (500metre drum) 368–312Table 2-2.
