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
