2.3.1.�Removing�the�flat�high-voltage�connector
Bridge�for�high-voltage�interlock�loop
Before�the�high-voltage�connector�can�be
disconnected,�the�bridge�for�the�high-voltage
interlock�loop�must�first�be�removed.�The�bridge
closes�the�circuit�of�the�high-voltage�interlock
loop�in�a�connected�state.�The�high-voltage
control�units�continuously�monitor�the�circuit�of
the�high-voltage�interlock�loop�and�only�when
the�circuit�is�closed�is�the�high-voltage�system
active.
If�the�circuit�of�the�high-voltage�interlock�loop
is�interrupted�by�removing�the�bridge,�the�high-
voltage�system�shuts�down�automatically.�This
is�an�additional�safety�precaution�as�the�Service
employee�has�already�switched�off�the�high-
voltage�system�before�beginning�work.
Removing�the�mechanical�locking
Only�after�the�bridge�of�the�high-voltage
interlock�loop�has�been�removed,�can�the
mechanical�locking�be�moved�in�the�direction�of
the�arrow.�The�mechanical�locking�is�an�element
of�the�high-voltage�connector�on�the�high-
voltage�components�(e.g.�electrical�machine
electronics).
By�moving�the�lock�in�the�direction�of�the
arrow�the�mechanical�guide�of�the�high-voltage
connector�on�the�high-voltage�cable�is�released
which�permits�the�subsequent�disconnection.
