Expanding the SIRIUS infeed system for 3RA6 by means of additional extension modules
Screw-type infeeds and extension blocks can be expanded by adding additional 3-slot and
2-slot extension modules.
The screw-type infeeds can only be expanded by adding modules to the right.
With spring-loaded connection technology, the extension module can be added to the right
or left, depending on which side the spring-loaded infeed has been installed.
WARNING
Danger, high voltage!
The maximum rated current for the extension connector is 63 A, regardless of the infeed
block. If the maximum rated current is exceeded, the extension connector will be damaged
beyond repair.
Make sure that the extension connector is never subjected to more than 63 A.
WARNING
Danger, high voltage!
Installing the extension connector on 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 installing the extension
connector.
