Please note:
][Verdrahtung ST analog  Safe electrical isolation must be ensured for the voltage supply to the
sensors and actuators. Failure to do so could result in electric shock.
 We recommend that you use shielded signal lines.
 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 mounting rail.
– Connect the mounting rail to the functional earth via an earthing
terminal.
 In environments with strong EMC interference, base modules without
a C-rail provide better protection if the shield is connected.
 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.

Procedure:
 Use a flat blade screwdriver (DIN 5264-A)!
 Strip the wire back 8 mm.
 If necessary, label the connection level with a colour marker [3].
 Base module with screw terminals:
– Use a screwdriver to loosen the screw on the screw terminal [1]
– Insert the stripped cable into the round fixing hole [2], as far as it
will go.
– Tighten up the screw on the screw terminal.
– Check that the cable is firmly seated.
