1.6 Cabling Requirements
The following requirements must be fulfilled when laying power and signal cables (These
are shielded cables unless specified).
Any signal cable used for high-voltage, high-frequency signals (inductive load ON/ OFF)
must be separated from other signal cables.
Separator
Provide a separator between power and signal cables as illustrated below:

Distance between Cables
If a separator cannot be used, keep a distance between signal cables and power cables.
The distances between cables due to operating voltages and currents are shown below.
