Technical Specifications

Installation Guidelines

• Mounting: Install the module in a vertical orientation to ensure adequate convection airflow through the cooling channels.
• Thermal Management: Given the heat dissipation involved in braking, ensure the cabinet is equipped with sufficient ventilation or climate control.
• DC Link Connection: The module must be connected to the DC link busbar of the inverter system. Ensure the cable cross-section is sized appropriately for the 20 kW peak load.
• Braking Resistor: This module requires an external braking resistor (sold separately). Ensure the resistor is sized to match the 20 kW power limit and mounted in a location where heat can be safely exhausted.
• Wiring: Use twisted-pair cabling for signal connections to minimize EMI, and ensure all power cables are properly shielded.
