R911309078 (HMS02.1N-W0028-A-07-NNNN)

What protection measures are required when installing the Bosch Rexroth HMS02.1N-W0028-A-07-NNNN to meet its short-circuit rating?

Since this unit can withstand 42 kA rms short circuits, you need to use upstream protective devices (circuit breakers or fuses) rated for that level or higher to avoid catastrophic failure, and ensure cabling/terminals can safely carry fault currents without damage.

How does the required installation clearance (80 mm above and below) impact cabinet design or cooling in industrial settings?

The 80 mm spacing ensures sufficient airflow for the internal blower to exhaust hot air and draw in cooler air; insufficient clearance will lead to elevated internal temperatures, potentially causing derating or premature failure of components.

What are the effects of operating this inverter in a humidity environment at the upper limit (≈95%)?

Very high humidity can lead to condensation forming on electronic components, so either dehumidified enclosure or conformal coating may be needed; otherwise, insulation breakdown or corrosion may occur, reducing reliability.

In what kind of motor load / application is the continuous current rating more relevant than the peak current rating?

For steady-state loads (like conveyor belts, pumps, or fan drives) that operate continuously, the 25 A continuous rating defines the safe operating current without overheating; the 28 A peak is useful only for brief demand surges (e.g. startup or acceleration).

How does the wide input voltage range (254-750 V DC) affect power supply design in multi-drive systems?

The broad DC input range provides tolerance for voltage drop or fluctuation in the DC bus, but to maintain efficiency and minimize voltage stress, the DC supply (or rectified AC source) should be stable; in multi-drive setups, proper sizing of conductors and bus capacitors is also critical.
