CABLE INSTALLATION
In line with IEE Wiring Regulations, the following should be observed:
•
Extra low voltage control cables (ELV) and mains power cable should be segregated by a
minimum distance of 50mm
•
If cables must cross, it is recommended that they cross at right angles
•
Airedale recommends that ELV cables are screened at one end to earthed enclosures
