Technical Specifications

Installation Guidelines

• Cooling: Mount the unit vertically on a flat surface. Ensure a minimum clearance of 100 mm above and below the device to facilitate air circulation through the internal heatsink.

• Environment: Ensure the ambient temperature remains between -10 degC and +50 degC. Avoid installation in environments with high humidity or conductive dust.

• Grounding: Ensure a high-integrity connection to the protective earth (PE) terminal to maintain the effectiveness of the internal Class A filter.

• Shielding: To comply with EMC regulations, use shielded motor cables and ensure the shield is bonded to the ground using EMC-compliant cable glands.
