Installation Guidelines
Ensure all incoming main power and external 24 V control supplies are completely isolated and locked out before performing mechanical mounting or wiring.
Mount the drive vertically on a flat, non-flammable surface inside an enclosure, ensuring adequate clearance above and below to allow proper thermal airflow.
Connect motor power cables using shielded cabling, terminating the shield securely at both the drive and motor chassis ground points.
Route low-voltage control, fieldbus, and I/O signal wiring physically apart from high-voltage power lines to mitigate electromagnetic interference.
