4.5 Cable routing
Defined ground!
The BTL and the control cabinet must be at the
same ground potential.
Magnetic fields
The position measuring system is a magnetostrictive
system. It is important to maintain adequate 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.
Inductive stray noise from AC harmonics (e.g. from phase
angle controls) are especially critical and the cable shield
offers very little protection against this.
Cable length
Max. cable length 20 m. Longer cables may be used if
their construction, shielding and routing prevent noise
interference.
