Removing additional extension modules
Screw-type and spring-loaded infeeds can be expanded by means of additional 3-slot and
2-slot extension modules. Screw-type infeeds can only be expanded by adding modules to
the right. Spring-loaded infeeds can be expanded by adding modules to the right or left,
depending on which side the spring-loaded infeed has been installed.
Danger, high voltage!
Removing the extension connector from the infeed system for 3RA6 while the system is live
can damage both the extension connector and infeed system and can also result in an
electric shock.
Remember to disconnect the system from the power supply before removing the extension
connector.
