1)
Unassigned leads can be connected to the GND on the controller side but not to the shield.
2)
Reference potential for supply voltage and EMC-GND.
3)
The voltage outputs may exhibit a minimal offset to the harmonized current output.

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 the BTL and controller using a shielded cable.
Shielding: Braided copper shield with minimum 85%.
– 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.
