Shielding and cable routing

Defined ground!
The BTL and the control cabinet must be at the
same ground potential.
Shielding
Observe the following instructions to ensure
electromagnetic compatibility (EMC):
– 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 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.
