7.1.8 Preparing the connecting cable for the remote version
When terminating the connecting cable, pay attention to the following points:
• In the case of electrode cables, make sure that the ferrules do not touch the core shields on
the sensor side. Minimum distance = 1 mm (exception: green “GND” cable)
• In the case of coil current cables, insulate one core of the three-core wire at the level of the
core reinforcement. You only require two cores for the connection.
• Fit the fine-wire cores with ferrules.
