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.
Shield: 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.
Magnetic fields
The position measuring system is a magnetostrictive
system. Ensure that there is sufficient distance between
the BTL 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.

Noise elimination
To avoid equipotential bonding - a current flow - through
the cable shield, please note the following:
– Use insulating bushes
– Put the control cabinet and the system in which the
BTL is located to the same ground potential.
