Above ~40 °C, the unit must derate its output to avoid overheating; continuous full-power (18 kW) performance isn’t guaranteed beyond that threshold. Proper ventilation and spacing are critical to maintain thermal stability.

Regeneration means that kinetic or braking energy is fed back into the DC-bus instead of being dissipated, reducing wasted energy and lowering overall power consumption. However, regeneration also increases stress on capacitors and switching components, so thermal design must accommodate higher internal losses during regeneration peaks.

The unit requires a vertical mounting position (G1) with sufficient top and bottom clearance (≈300 mm top, ≈130 mm bottom) so the internal blower can draw in air properly without recirculating heated air. Lack of clearance can result in elevated internal temperature rises (~65 K) and degraded reliability.

A 700 V DC-bus means all downstream wiring, insulation classes, and drive inputs must be rated above that voltage; cable length and skin-effect losses grow at high current in high voltage setups. Also, safety clearances and surge suppression (e.g. from regenerative switching) become more critical.

The 24 V control supply sees an inrush current of up to ~5.5 A, which may be higher when brake-motor cables exceed about 50 m; thus designers should include inrush current limiting and ensure supply wiring can handle transient peaks without voltage drop.
