Rittal cables – measures to prevent or mitigate electrical interference
1. One spare core of the control cable is grounded
It has been proved in practice that when a spare core in the control cable is grounded, the amplitude of the interference voltage can be reduced to 25%-50%, and the implementation is simple, and the cost of the cable is increased very little.
2. Serious consequences will occur when electrical interference is generated.
