Loosen

1

Loosen safety screw (1).

2

Press locking element (2) against the spring force up to the end stop in the direction of the arrow and keep pressed.

 Both mounting frame bows (2.1) are released from the holding lugs (4) at the high-voltage connection.

3

Detach high-voltage plug (3) from the high-voltage connection.

 Do not pull on the electrical lines.
Otherwise, damage to the electric lines and the high-voltage plug (3) will occur.

Mount

4

Insert high-voltage plug (3) into the high-voltage connection until the mounting frame bow (2.1) engages in the holding lug (4).

 Do not handle high-voltage plug (3) on the electric lines and do not tilt when installing.
Otherwise, damage to the electric lines, the high-voltage plug (3), and the mounting frame bows (2.1) will occur.

 Both mounting frame bows (2.1) must fully surround the holding lugs (4).
Otherwise failure of the high voltage on-board electrical system can occur.
