The line reactors for Power Modules, frame sizes A - E, are designed as sub-chassis
components.
The line reactor is retained on the mounting surface and the Power Module is mounted on
the line reactor in a space-saving fashion. The cables to the Power Modules are already
connected at the line reactor.
The line reactor is connected to the line supply through terminals.
The reactors for Power Modules, frame sizes F, FX and GX are, as a result of their weight
and their size, separately mounted.
