and refer to the use:

– In control cabinets and machines

– Installation in the cable duct

– Maximum ambient temperature +40 °C

ƒ The cables between the braking unit and the controller may not exceed a

length of 2 m.

– For cable lengths £ 0.5 m you can use unshielded single cores.

ƒ If an interference suppression of the drive system is required, the cables

have to be shielded

– Always apply the shield on both sides.
