Installation and Maintenance
Pre-installation preparation: Ensure the electrical cabinet meets IP20 standards and provides 50 mm clearance around the ELAU MAX-4-11-03-128-99-1-1-00 for convection cooling. Verify input voltage stability (±10% tolerance) and ground continuity. Use shielded cables for motor feedback to prevent EMI interference. Mount the drive vertically on DIN rails using TS-35 compliant hardware.
Maintenance recommendations: Inspect terminal connections bi-annually for corrosion or loosening. Monitor heat dissipation paths; clear dust buildup near heatsinks quarterly. For firmware updates, use ELAU’s ServiceSuite tools via the front-port interface. Replace the ELAU MAX-4-11-03-128-99-1-1-00 if error codes persist after resetting, indicating internal component wear.
