3.1.2 Cables
Cables with a high level of interference and cables with a low level of interference are
connected to the converter.
Note
Cables with a high level of interference must be shielded.
● Cables with a high level of interference:
– Cable between the line filter and converter
– Motor cable
– Cable between the converter and external braking resistor
● Cables with a low level of interference:
– Cable between the line and line filter
– Signal and data cables
Cable routing inside the cabinet
● Route the cables with a high level of interference so that there is the largest possible
clearance to cables with a low level of interference.
● Cables with a high level of interference and cables with a low level of interference may only
cross over at right angles:
● Keep all of the cables as short as possible.
● Route all of the cables close to the mounting plates or cabinet frames.
● Route signal and data cables - as well as the associated equipotential bonding cables -
parallel and close to one another.
● Twist incoming and outgoing unshielded individual conductors.
Alternatively, you can route incoming and outgoing conductors in parallel, but close to one
another.
● Ground any unused conductors of signal and data cables at both ends.
● Signal and data cables must only enter the cabinet from one side, e.g. from below.
● Use shielded cables for the following connections:
– Cable between the converter and line filter
– Cable between the converter and motor
– Cable between the converter and external braking resistor
