Installation Guidelines

  • Mounting: Mount the drive vertically on a flat, vibration-free surface. Ensure that the cooling air intake and exhaust are not obstructed.
  • Environmental Considerations: The IP54 rating protects against splashing water and dust, but the unit must not be submerged or exposed to high-pressure cleaning.
  • Grounding: Proper grounding of the drive chassis is essential to ensure the effectiveness of the internal EMC filter and to comply with electrical safety standards.
  • Cable Selection: Use shielded power and control cables to maintain EMC performance. Keep motor cables as short as possible to minimize radiated interference.
  • Ambient Temperature: Ensure the installation area temperature remains within the specified operating range to prevent thermal derating or failure.
