Cable termination in remote version
Promag W, Promag P
Terminate the signal and coil current cables as shown in the figure below (Detail A).
Fit the fine-wire cores with wire end ferrules (detail B: m = red ferrules, Ø 1.0 mm; n = white ferrules, Ø 0.5 mm)
* Stripping for reinforced cables only

Caution!
When fitting the connectors, pay attention to the following points:
• Signal cable → Make sure that the wire end ferrules do not touch the wire shields on the sensor side!
Minimum distance = 1 mm (exception "GND" = green cable)
• Coil current cable → Insulate one core of the three-core wire at the level of the core reinforcement; you only require two cores for the connection.
