3.3.3.3
3.3.3.4
The PE jumper begins at the power terminal of the 120 V AC/230 V AC area and, in a
complete AC voltage area, ends at the end terminal.
If a terminal is removed from this area, the PE jumper is interrupted.
If the installation instructions have been followed, all subsequent terminals will be
disconnected.
3.3.4
Power-level terminals are located in a power housing.
Low-level signal terminals and low voltage terminals are located in the same type of
housing, which is referred to as low-level signal housing. An external feature that
distinguishes the base and the corresponding connectors of low voltage terminals from the
base and connectors of low-level signal terminals is their color:
Table 3-2
WARNING: Dangerous contact voltage
The supply voltage must only be provided at the appropriate power terminal.
If you provided voltage to several places in an incomplete Inline station, there would be a
danger of touching live parts.
The connecting cables of all actuators and sensors must only be connected to the Inline
terminals for the relevant voltage area. The use of external bus bars for group potentials
is not permitted.
