Shielding and cable routing

Defined ground!
The position measuring system and the control
cabinet must be at the same ground potential.
Shielding/cable routing
To ensure electromagnetic compatibility (EMC), observe
the following:
– The cable shield must be grounded on the controller
side, i.e. connected to the protective earth conductor.
This does not apply to IO-Link cables (unshielded, see
accessories on page 20).
– When ducting the cable between the sensor, controller,
and power supply, it is important to avoid going near
high voltage cables due to interferences.
Stray noise from AC harmonics (e.g. from phase angle
controls or frequency converters) are especially critical
and the cable shield offers very little protection against
this.
Bending radius
For information on the permissible bending radius, see the
connector on page 20.
Cable length
IO-Link recommends to limit the cable length to 20 m.
Longer cables may be used if their construction, shielding
and routing prevent noise interference.
