For fault-free CC-Link operation, the following measures are necessary:
The bus cables must be twisted and shielded (refer to the definition of
Mitsubishi) and are to be routed separately from power cables, the
minimum clearance has to be 20 cm. The shield must be connected
through the largest possible surface area on both sides, i.e. the shield
of the bus cable between 2 converters must be connected to the
converter housing at both ends.
If bus and power cables intersect, they must cross at an angle of 90 °.
Attaching the shield with the help of shield clamps:
The shield of the bus cable can be attached to the converter housing
with the help of shield clamps (Compact units) or shield clamps and
cable ties (chassis units). How to use the shield clamps is shown in Fig.
3-3 and Fig. 3-4.
Attaching the shield also to the pin SLD of CBL.
