10.5.5 Grounding
Control failure due to insufficient grounding
NOTICE
An optimum grounding is required to keep away possible interferences from the
control and to discharge them to the ground.
Functional earth
Only the functional earth (FE) is used for the IndraControl XFE01.1-
SY-01 controls, extension modules and the IndraControl S20
components. The functional earth (FE) is only used to discharge
disturbances. For individuals, the functional earth is not intended as
protection against electric shock.
The control is grounded via the top-hat rail. The top-hat rail, on which the
control is mounted, has to be mounted to a grounded metal carrier, e. g. the rear
panel of the control cabinet.
The IndraControl XFE01.1-SY-01 control and the IndraControl S20 I/O modules
are at least provided with one FE spring (metal clip) at their lower side creating
an electric connection to the mounting rail while mounting.
If necessary, provide the top-hat rail with a separate grounding connection.
Voltage jumper
The voltage jumper FE (functional earth) is routed from the control through all
connected IndraControl S20 modules. This ensures that these terminals are
grounded once the control, the supply terminals and the top-hat rail were
grounded properly.
Potential equalization
Potential equalization acc. to DIN VDE 0100 part 540 has to be provided
between the system parts and the voltage supply.
Information on the protective conductor system
All system components have to be connected to the PE protective conductor
system at the connectors marked accordingly.
