Installation Guidelines

Mounting Orientation: Install the drive vertically on a flat, non-flammable surface to maintain optimal convective airflow.
Clearance Requirements: Ensure sufficient top, bottom, and side clearance for Frame Size E dimensions to prevent thermal bottlenecks within the electrical panel.
Wiring Precautions: Use shielded motor cables and route them separately from control signaling to prevent electromagnetic interference.
Grounding: Connect the protective earth terminal (PE) directly to a low-impedance facility ground line.
