Special measures when establishing connections
When routing cables over longer distances, e.g. between remote control cabinets, you have
the following options to reduce the risk of damaged cables when your plant or machine is
operating:
● Use shielded cables with grounded shield.
● Lay signal cables in steel pipes.

4.3.2.1

Connecting sensors

Electromechanical sensor
If there is a risk of cross-circuits or short-circuits, the cables between the sensor and the
inverter must be protected, for example, by routing them in a steel tube.
The inverter provides the supply voltage
