8.6 Double Cabling
A motor connection with two power cables is required if a corresponding
single cable cannot be used due to the large bending radius or due to its
dimensions.
Note: Double cabling can only be accomplished on motors
equippment with a terminal box (see Fig. 8-6).

Note:
• Conductors not shown in the switching diagram are not
required and must not be connected.
• The fuses F1 (NH...), to protect the conductors in case of
overload at cable break, are dimensioned according to the
current rating based on the cross-sections of the individual
conductor.
• The fuses should be installed in the electrical cabinet so
that they are as close as possible to the power output of
the drive device.
• The shields of the power cables should be connected to the
electrical cabinet with the largest possible surface area.
• Cable pairs must be properly connected to the terminal
strips or to the terminal studs of the drive controllers; they
must also fulfill safety regulations.
Therefore, observe the following documentation:
