Electrical connection
Depending on the model, the electrical connection is made
using a cable or strands.
The connection assignments can be found in Table 4-2.
Note the information on shielding and cable
routing.

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.
–
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).
–
Strand version: Observe note on shielding (see page 8).
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.
