Procedure for installing the converter

Prerequisites for installing the converter
Check that the following prerequisites are fulfilled before you install the converter:
● Are the components, tools and small parts required for installation available?
● Are the ambient conditions permissible? See Technical data (Page 295).
Installation sequence

EMC-compliant cabinet design

The most cost-effective method of implementing interference suppression measures within
the control cabinet is to ensure that interference sources and potentially susceptible
equipment are installed separately from each other. This must be taken into account already
during the planning phase.
EMC-zone concept within the control cabinet
The control cabinet has to be divided into EMC zones and the devices within the control
cabinet have to be assigned to these zones. The example below illustrates this zone concept
in greater detail.
