1.3 CLEARANCE AND CREEPAGE (DISTANCE FOR
INSULATION)
Clearance
Clearance between windings and other
metallic materials has to be 3mm or
more, and this condition has to be
applied for all directions of windings.
These are described in VDE0110. Refer
to VDE0110 for details to conform to
CE marking.
Creepage distance
Creepage distance depends on materials used for insulation. In the
case of general plastic material under IP54 condision, it has to be
2.5mm or more. Refer to VDE0110 for details.
NOTE
Clearance and creepage distance described here
change depending on environment and materials.
Therefore confirm actual value that is suitable for
your machine system.
Terminal block and connector
Use IEC- or UL-certified terminal blocks and connectors for power
leads connection when required.
For the clearance and creepage distance between terminals, conform
to IEC664-1.
