Installation Guidelines

• Mounting: Mount the drive vertically in a clean, ventilated enclosure to ensure proper heat dissipation. Maintain recommended clearance distances around the unit.
• Cabling: Use shielded cables for the motor connection to minimize electromagnetic interference (EMI). Separate signal/control wiring from power cables.
• Cooling: Ensure the internal cabinet fans or ventilation system are functioning correctly, as the drive is rated for an ambient temperature range of 0 to 50 degC.
• Grounding: Use a solid, low-impedance earth connection to the drive chassis to meet electrical safety standards and reduce common-mode noise.
• Configuration: Utilize the integrated control terminal or compatible software tools to set parameters, such as ramp-up/ramp-down times and motor protection settings.
