Customer terminal strips
The signals are allocated to various terminal strips according to voltage level. The cables are
visually distinguished from one another by various colors. Barriers mechanically separate cables
carrying different potentials on one terminal strip. The terminals are suitable for cables with a
cross-section of 2.5 mm

.
The default setting and interfaces of the customer terminal strips can be found in the circuit
manual. For information about the position of the customer terminal strips within the cabinet,
