Please note:
][Verdrahtung ST INC  The module's connections are galvanically isolated from the module
supply and periphery supply.
 For EMC reasons we recommend that you operate inputs A, B, C ex-
clusively as differential inputs with inverted signals (A+/A-, B+/B-, C+/
C-).
 The module evaluates open differential inputs (A+/A-, B+/B-, C+/C-)
as a 1 signal.
 The module evaluates open function inputs (G, L, S) as a 0 signal.
 Use twisted pair cables to carry the inverted signals. This will increase
the noise immunity.
 Use shielded signal cables with metallic plugs.
 On base modules with C-rail:
– Connect the shield to the terminals on the C-rail.
– Connect the C-rail with low impedance to the functional earth.
 On base modules without C-rail:
– Connect the shield as shown in the terminal configuration section.
– The module connects the shield to the functional earth via the
mounting rail.
 The channel for the incremental encoder's zero pulse has a different
designation depending on the manufacturer (N, C, Z, 0,...)
 The supply voltages must be extra low voltages with safe electrical
separation (PELV or SELV) in accordance with VDE 0100, Part 410.
 Use copper wiring.
][Verdrahtung Zusatz mit C  The terminal configuration as stated on the front plate applies for base
modules with C-rail. The terminal configuration as stated in the tech-
nical documentation applies for all other base modules.
