DC interface incl. pre-charging for Motor Modules in the chassis format
The main component of option L37 is a switch disconnector. This switch disconnector is
installed on the busbar between the Motor Module and the DC busbar. This option also
includes a pre-charging switch for the DC link capacitors of the relevant Motor Module so
that it can be switched in to the pre-charged DC busbar.
This switch can be actuated using an operating lever but only when the cabinet door is
closed.
As an air guide, option L37 also includes option M60 (additional shock protection).
Note
This option is not used for switching the module on and off during operation.
