Install, maintain and modify customer premises communications cabling: ACMA Lift Rule


Application

This unit describes the skills and knowledge required to safely install, maintain and modify communications cabling required on a customer's premises, according to Australian Communications and Media Authority (ACMA) Lift Cabling Provider Rule.

It applies to individuals who are qualified licensed electricians working in technical roles for lift installations on new or upgrade installations for an existing network or subsystem for convergence to next generation network (NGN) applications.

All customer cabling work in the telecommunications, fire, security and data industries must be performed by a registered cabler. All cablers are required to register with an ACMA accredited registrar.

4.6 Install cable fasteners with correct tension to prevent cable sheath damage or transmission impairment, and trim flush to prevent risk of personal damage

4.7 Install aerial cables supported by catenaries in external environment to meet minimum above ground clearances and clearances from hazardous electrical services according to current Australian Standards

4.8 Install and secure travelling cables to maintain safety and according to relevant legislative, industry and manufacturer’s standards

4.9 Install local isolation units (LIU) as required according to current Australian Standards

4.10 Install over-voltage protection devices to all cable pairs, where required, to suppress voltage surges, with devices protectively earthed and according to current Australian Standards

4.11 Protect earth wire insulation against damage with protective earths segregated according to relevant industry and legislative standards

5. Terminate and test cables and earth wires

5.1 Remove cable sheath to allow for correct termination length and without damage to underlying conductors and their insulation

5.2 Install terminating modules according to manufacturer’s specifications, ensuring cable pairs are neatly and sequentially fanned for termination

5.3 Terminate conductors according to recommended colour code sequence using appropriate termination tools in manufacturer’s specified manner

5.4 Earth cable shield, if applicable, to manufacturer’s specifications and relevant industry codes of practice, including current Australian Standards

5.5 Undertake visual inspection to confirm termination colour code sequence has been followed, prior to end to end testing of wire and pair termination integrity

5.6 Terminate earth wires with connectors recommended by manufacturer according to relevant industry codes of practice, including current Australian Standards

5.7 Maintain earth wire continuity throughout to meet interface requirements with electrical systems

5.8 Test earthing installation for continuity, insulation resistance and conductive resistance according to relevant industry standards, including current Australian Standards

5.9 Confirm compatibility of alterations with existing systems and test new work both in isolation and when integrated with existing systems

6. Inspect cable route to ensure correct separations

6.1 Inspect separations along entire cable route and rectify separations that do not comply with regulations

6.2 Install barriers to achieve separations where sufficient spatial separation cannot be met

7. Evaluate earthing needs for cable systems on customer premises

7.1 Locate existing customer earthing systems and analyse earthing needs of cable systems

7.2 Calculate upper and lower limits of resistance for variety of cable system earths using relevant cable characteristics

8. Label earthing systems

8.1 Identify label requirements for all types of earthing systems

8.2 Attach label to earthing systems according to industry regulations

9. Create or update cable plans and records

9.1 Document installation details on record sheets and plans, and store according to customer requirements

9.2 Label cable pairs clearly to provide accurate identification according to manufacturer's, industry and customer standards

9.3 Record cabling details in cable pair record books to provide accurate record according to industry codes of practice and current Australian Standards

9.4 Complete Telecommunications Cabling Advice (TCA) form
