Fig. 6-59: Shield contact, alternative 2
• With a cable tie (2) press the drive-side cable end in such a way that
the shields of the two inner pairs of wires (motor temperature, holding
brake) have good contact with the overall shield of the motor power
cable (3).
(If you use your own cable make sure the shields of the two inner
pairs of wires are in contact with the overall shield.)
• On the level of the ground bus in the control cabinet remove a piece
of the cable sheath from the motor power cable in order to lay bare
the overall shield (5).
• Connect overall shield (5) to ground bus in the control cabinet with an
appropriate connection (clip). The connection must have a cross
section of at least 10 mm

.
• With a cable (6) (line cross section at least 10 mm
2)
connect ground
bus (4) to ground connection at supplying device (Rexroth IndraDrive
supply unit or Rexroth IndraDrive drive controller HCS).
• Make sure there is sufficient strain relief for the motor power cable as
near as possible to the drive-side cable end (7).
