It means only motors and inverters rated for up to about 700 VDC (or more) can be driven directly without additional step-up/down conversion. Also, insulation, clearances, and safety devices must be designed to safely handle this voltage to avoid arcing or breakdown.

A considerable portion of input power will be lost as heat in rectification, switching, and conduction losses—expect several kilowatts of waste heat. The cooling system must be sized so that ambient temperatures up to +40 °C don’t push component junction temperatures above safe limits (as per Bosch’s manual).

Operating outside nominal 50-60 Hz will slightly change the input current, and possibly derate performance, because rectifier and intermediate circuit loads depend on the mains frequency. Within 48-62 Hz Bosch allows that tolerance without needing to recalibrate, but beyond that efficiency and cooling margin suffer.

These capacitors provide a reference/return path to reduce electrical noise and meet EMC standards; however, they also create leakage currents which must be grounded properly. Cabling layout and chassis bonding are important to avoid ground loops or unexpected interference.

It is well suited for multi-axis robotics, CNC machining centers, or large automation lines where a stable high DC bus is shared among drives. It might be overkill for single small axis or low kilowatt tasks, where lower power or simpler supply units would be more cost-effective.
