Cable termination in the non-hazardous area
!
The cable armor must be connected to safety earth in the safe area.
!
The cable screen (drain wire) must be connected to an instrument earth in
the safe area.
!
The power supply OV return must be connected to an instrument earth in
the safe area.
!
The interconnecting cables should be segregated from power and other
noisy cables. Avoid proximity to cables associated with radio transmitters,
welders, switch mode power supplies, inverters, battery chargers, ignition
systems, generators, switch gear, arc lights and other high frequency or high
power switching process equipment. In general, maintain separation of at
least 1m between instrument and other cables. Greater separations are
required where long parallel cable runs are unavoidable. Avoid running
instrument cable trenches close to lightning conductor earthing pits.
!
Complete all cable insulation testing before connecting the cable at either
end.
WARNING - Under no circumstances should equipment be connected or
disconnected when under power. This is contrary to hazardous area regulations
and may lead to serious damage to the equipment. Equipment damaged in this
manner is not covered under warranty.
