Usage and Maintenance

Install with cabinet airflow ≥ 100 m³/h to ensure proper cooling

Operate below 45 °C to avoid performance derating

Configure DA02 analog range (±10 V) and feedback type via IndraWorks

Clean internal air passages every 6 months to prevent dust buildup

Calibrate control loops and feedback system annually
