The 12-wire connecting cable is used to wire all inputs and outputs of the sensor. The cable comes in
two different temperature versions. For more information, see section see section 9.9 Terminal Box,
page 62 and section 9.11 High Temp Cable, page 64.
The following figure shows how to configure the drain wires of the cables before connecting to the
sensor. The bare wire with the clear shrink tubing (cable shield) must be connected to the terminal
labeled CLEAR.

The factory default setting for the Marathon MM is the 4-Wire Mode!
The complete wiring must have only one common earth ground point!
Power supplies based on a IT grid structure could cause an unintended reset of the
sensor. To avoid this, consider a sensor mounting isolated from the machinery!
