2.12.2 Field Cabling
The entire length of the field cabling connected to a unit should be screened / shielded.
•
The screen / shield should be connected to a low noise instrument earth at one end.
The screens / shields of field cabling must not be connected in a manner that creates
•
earth loops or that will result in the screens / shields carrying large currents from heavy
plant or equipment.
2.12.3 Interference and noise
•
Electrical equipment connected to the system should comply with applicable national or
international EMC standards.
•
Ideally, the 24 V supply reaching units should be free from large transients, fluctuations
or high frequency noise.
•
In order to reduce the likelihood of radio frequency interference affecting the operation
of units it is recommended that neither units nor their cabling are installed in close
proximity to the antennae of high-powered radio, radar or satellite communication
equipment.
