The￿high-voltage￿contacts￿of￿the￿round￿high-voltage￿connector￿for￿the￿EKK￿are￿protected￿against
contact.
The￿high-voltage￿connector￿of￿the￿EKK￿is￿not￿part￿of￿the￿circuit￿of￿the￿high-voltage￿interlock￿loop.
The￿electrical￿capacity￿in￿the￿EKK￿is￿less￿than￿100￿µF.￿This￿capacity￿is￿discharged￿via￿a￿passive￿resistor
in￿the￿EKK.￿After￿the￿EKK￿is￿shut￿down￿the￿voltage￿falls￿to￿below￿60 V￿in￿less￿than￿5￿seconds.
