4.4 Electrical Connection
Depending on the model, the electrical connection is made
using a cable or a connector.
The connection or pin assignments for the respective
version can be found in Tab. 4-2.
Note the information on shielding and cable
routing in section 4.5.

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.
– Connector version: Shield is internally connected to
connector housing.
– Cable version: On the BTL side the cable shielding is
connected to the housing.
Ground the cable shielding on the controller side
(connect with the protective earth conductor).
Magnetic fields
The position measuring system is a magnetostrictive
system.
Ensure that there is sufficient distance between the BTL,
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.
Bending radius for fixed cable
The bending radius for a fixed cable must be at least five
times the cable diameter.

Prerequisite: Construction, shielding and routing preclude the effect of any
external noise fields. Required cable cross-section ≥ 0.6 mm
