Installation of cables
Wiring of the sensors should be routed separately or screened from heavy conductor lines,
as in extreme cases inductive peak voltages can destroy the sensors despite the integrated
protective circuit. Screened cable or twisted lines are recommended, especially for longer cable
runs > 5 m.
