Installation Guidelines

• Mounting: Install the drive vertically on a flat, non-flammable surface to optimize heat dissipation.
• Clearance: Maintain a minimum clearance of 100 mm above and below the unit, and 50 mm on both sides for adequate ventilation.
• Grounding: Ensure the ground terminal is securely connected to a dedicated industrial earth ground to minimize electromagnetic interference (EMI).
• Wiring: Route control signal cables and power cables through separate conduits to prevent signal degradation. Use shielded cables for control signals and encoder feedback.
• Operating Environment: Install in an environment free from corrosive gases, oil mist, and excessive dust, with ambient temperatures maintained within the rated limits without condensation.

Compliance and Certifications

• CE Mark (Low Voltage and EMC Directives)
• UL Listed / cUL Listed (US and Canadian safety standards)
• RoHS compliant
