Description
The converter connection cables have dierent interference levels:
• Cables with a high level of interference:
– Cable between the line lter and converter
– Motor connection cable
– Cable at the converter DC link connection
• Cables with a low level of interference:
– Cable between the line and line lter
– Signal and data cables
EMC-compliant cable routing complies with the following requirements:
• All cables are as short as possible.
• All cables are routed close to the mounting plates or control cabinet frames.
• Power cables with a high level of interference are routed so that there is a minimum clearance
of 20cm to cables with a low level of interference.
If the minimum clearance of 20 cm is not possible, insert separating metal panels between
the cables with a high level of interference and those with a low level of interference. The
separating metal panels are connected to the mounting plate to establish a good electrical
connection.
• Cables with a high level of interference and cables with a low level of interference only cross
over at right angles.
• All signal and data cables only enter the control cabinet from one side, from below, for
example.
• Signal and data cables, as well as the associated equipotential bonding cables, are routed in
parallel and close to one another.
• Any unused conductors of signal and data cables are grounded at both ends.
• Incoming and outgoing individual conductors that are not shielded are twisted with one
another.
Alternatively, incoming and outgoing conductors are routed in parallel, but close to one
another.
