The cable with pre-assembled USB and tab connectors can also be ordered as an individual
item for installation on molded case circuit breakers prepared for use as draw-out units.
For detailed instructions on how to install the communications interface for the draw-out unit,
please refer to the relevant Operating Instructions
( http://support.automation.siemens.com/WW/view/en/80597324 ).
For instructions on how to read out data via remote data transfer, refer to the operating

Auxiliary circuit connector
①
Plug-in technology
②
Draw-out technology
Auxiliary circuit connectors are required only if the molded case circuit breaker to be
converted to plug-in or draw-out technology is equipped with internal accessories. Plug-in
units use a different design of auxiliary circuit connector than draw-out units.
The number of auxiliary circuit connectors required depends on the accessories to be
installed in the molded case circuit breaker and ultimately on the number of electrical
connections which need to be brought out of the molded case circuit breaker. Each auxiliary
circuit connector can be used to connect up to four cables. Accordingly, the breaker-end and
socket-end halves of the auxiliary circuit connectors have four screw-type terminals which
are labeled ".1" to ".4".
