To maintain safe junction temperatures, adequate airflow through the internal blower is needed and ambient temperature must remain within 0-40 °C; high duty cycles or reduced cooling airflow will require de-rating the current

Although the driver can reach a maximum current of 350 A, its continuous (or “constant”) current rating is lower (≈ 250 A) to avoid thermal stress, so for sustained operation design for the continuous current limit.

The control and logic circuits require 24 V, but since the unit is “not equipped” with internal power supply, you’ll need an external 24 V source with enough capacity; failure or instability there can cause control malfunctions or loss of safety interlocks.

Motor connections and grounding must follow specified copper cross-section wire (material: Cu, conductor temp rating 60/75 °C), with proper grounding of the frame, ground straps, and EMC shielded cable to meet the EMC / UL specifications in the manual.

At continuous current and with nominal DC bus usage, power dissipation can reach up to ~2750 W based on UL specs for this power class, meaning substantial cooling and heat sink/enclosure design must be accounted for.
