IMPORTANT:
The outer shield should be connected to the machine earth (Field Ground). The inner
shield should be connected to 0 V at receiving electronics only. Care should be taken to ensure that the
inner and outer shields should insulated from each other. If the inner and outer shields are connected
together, this will cause a short between 0 V and earth, which could cause electrical noise issues.
