Installation Guidelines

• Mounting: Due to the weight and IP54 rating, ensure the drive is securely mounted on a structurally sound, vertical wall or panel surface.
• Environmental: The IP54 rating allows for operation in more challenging environments, but the unit should still be protected from direct weather exposure and extreme temperatures.
• Wiring: Utilize shielded motor cables to maintain the integrity of the Class B EMC filtering. Properly route control and power cabling to avoid electromagnetic noise.
• Grounding: Establish a high-integrity connection to the system protective earth to ensure safety and performance compliance.
• Cooling: Ensure the installation area provides sufficient clearance for heat dissipation, as the drive performance can be affected by internal temperature accumulation.
