Shielding and cable routing

Defined ground!
The linear encoder system and the control
cabinet must be at the same ground potential.
Shielding
To ensure electromagnetic compatibility (EMC), observe
the following:
– The cable shield must be grounded on the controller
side, e.g. connected to the protective earth conductor.
– 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
Connector on page 29.
Cable length
Cable length max. 20 m. Longer cables may be used if
their construction, shielding and routing prevent noise
interference.
Observe voltage drop in cable!
The Balluff Connector (see section 10.6 on
page 30) has a resistance of approx. 0.4
Ohms/m (out and back). Do not allow the
operating voltage to the BML to drop (see
Tab. 10-1 on page 30).
