4.4 Electrical connection
The BTL is connected via a connector.
The pin assignments for the respective version can be
found in Tab. 4-2 and Tab. 4-3.
Note the information on shielding and cable
routing.

4.5 Shielding and cable routing
Defined ground!
The BTL and the control cabinet must be at the
same ground potential.
Shielding
To ensure electromagnetic compatibility (EMC), observe
the following:
– Connect BTL and controller using a shielded cable.
Shielding: Braided copper shield with minimum 85%
coverage.
– Shield is internally connected to connector housing.
Magnetic fields
The position measuring system is a magnetostrictive
system.
Ensure that there is sufficient distance between the BTL
and between the transducer/holding cylinder and strong,
external magnetic fields.
Cable routing
Do not route the cable between the BTL, controller, and
power supply near high voltage cables (inductive stray
noise is possible).
The cable must be routed tension-free.
Cable length
The maximum cable length when using CAT5e cables is
100 m

Prerequisite: Construction, shielding and routing preclude the effect of any
external noise fields.
