Should larger cable cross-sections be required for the installation than the maximum cross-section of
the UPS terminals, a socket or a terminal box can be installed near the UPS. From there to the UPS, a
cable laying with a smaller cross-section can be possible (better laying conditions such as installation
type, cable length, ...).
