the shield busbar (4) into the receptacles of the shield busbar supports (1).
Connect the cores (5) of the motor cable (6) and then fasten the copper-sheathed end (7) of the motor cable
(6) to the shield busbar (4) using the shield clamp (8). Tighten the screw (9) to the stop.
Connect all wires for the feedback system (14).
Secure the PE core (10) of the motor cable (6) under the PE clip (11) and securely tighten the screw (12) of
the PE clip. Move the indicator bracket (13) into the vertical position and lock it.
