3.4.9. Ground continuity compliance
The Motors must meet the standards IEC 60204-1.
Continuity of the grounding circuit : On each complete unit, the resistance between
any conductive point and the grounding conductor shall not exeed than100 m

. This
test shall be performed before the dielectric tests. (EN 60204-1: Safety of the
machine)
3.4.10. Protection rating
cf. IEC 60529 and IEC 60034-5
The K Series Kit Motors show an IP00 protection rating. It is the integrator's
responsibility to ensure the appropriate protection rating depending on the use of the
motor (protection against electric shocks of persons, protection against dust, liquids,
solid particles
