7.6.1.5. Minimum Creepage Distance
When using spacers for cable connection to a busbar, the minimum required
creepage distance must be observed. Depending on the comparative tracking
index (CTI) of the insulation material of the cable the following minimum creepage
distances (MCD) apply:
If the CTI value of the insulation material is unknown, the values in row three of the
table apply. The spacers shown in are installed to guarantee for the minimum
creeping distance. Since cable sheaths are not normally rated for high voltage
insulation, the minimum distance must be guaranteed.
7.6.1.6. Splitting multi-core cables
This section applies to drives without an additional cabinet.
–
Check the distance between point of cable entry and closest busbar.
–
Check the cable diameter.
–
If distance and cable diameter do not allow bending the cable inside the
terminal compartment, separate the conductors outside of the terminal
compartment.
