Preparation
ƒ Remove cover of the power connections.
ƒ Remove cover of the control connections.
6.3.1 Power connections
ƒ The data regarding cable cross−sections and fuses are recommendations
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.
ƒ It is the user’s responsibility to take further standards (e. g.: VDE 0113,
VDE 0289, etc.) into consideration.
