Warning
Before carrying out installation and maintenance work,
switch off the following:
the operating and load voltages on the higher−order sys
tem (e.g. CP field bus node)
if necessary, the separate supply voltages.
You can thereby avoid:
unexpected movements of the connected actuators
non−defined switching states of the electronic compo
nents.
Warning
Connect the earth connection on the side of the housing
(see Fig. 1/1) with low impedance (short cable with large
cross−sectional area) to the earth potential.
In this way you can avoid faults due to electromagnetic
influences and ensure electromagnetic compatibility in
accordance with EMC guidelines.
