Shielding and cable routing
Defined ground!
The linear encoder 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, i.e. 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.
Magnetic fields
The linear encoder is a magnetic system. It is important to
maintain adequate distance between the linear encoder
and strong, external magnetic fields.
Cable routing
Do not route the cable between the linear encoder,
controller, and power supply near high voltage cables
(inductive stray noise is possible).
The cable must be routed tension-free.
Bending radius for fixed cable
The bending radius for a fixed cable must be at least
7.5 times the cable diameter.

Cable length
Max. cable length 20 m. Longer cables may be used if
their construction, shielding and routing prevent noise
interference.
Startup
DANGER
Uncontrolled system movement
When starting up, if the linear encoder is part of a closed
loop system whose parameters have not yet been set,
the system may perform uncontrolled movements. This
could result in personal injury and equipment damage.
► Persons must keep away from the system's
hazardous zones.
► Startup must be performed only by trained technical
personnel.
► Observe the safety instructions of the equipment or
system manufacturer.
1. Check connections for tightness and correct polarity.
Replace damaged connections or devices.
2. Turn on the system.
3. Check measured values in the controller and reset if
necessary.
