The�high-voltage�system�must�not�be�operated�if�the�potential�compensation�cables�are�not�properly
connected�to�the�high-voltage�components.
If�in�the�event�of�a�repair�the�high-voltage�components�or�the�potential�compensation�lines�are
replaced,�the�following�must�be�observed�during�assembly:�The�galvanic�connection�between�the
housing�of�the�high-voltage�components�and�ground�must�be�properly�re-established.�The�repair
instructions�must�be�strictly�observed�(tightening�torque,�self-cutting�screws).�In�addition,�a�second
Service�employee�has�to�check�the�repair�work�(correct�tightening�torque�and�correct�location�of�bare
metal)�and�record�this�in�writing�in�the�repair�order.
