Warning
Before carrying out installation and maintenance work,
switch off the following:
S the load voltage on the relevant output module.
Also switch off the following when carrying out installation
work:
S the operating voltage supply for the higher−order system
S the load voltage supply for all the output modules
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. 2/1) 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.
