Please comply with Chapter 9 Additional requirements for the servo drives concerning the UL approval on
page 113.

Heidenhain encoder: ASIN_Z0; BCOS_Z0
In addition, a low-impedance connection of the outer cable shield to the housing of the
servo drive has to be established. Therefore, the outer cable shield of the angle
encoder cable must be connected to the housing of the angle encoder connector.
