Selection & installation notes
- Do not select a 380 V supply from the generic illustration: the current prose excludes that option. Confirm availability and a model-specific rating sheet first.
- The source labels the switching thresholds as “turn-on ≤4 V” and “turn-off ≥1 V”. These are threshold descriptions, not instructions to turn on below 4 V or turn off above 1 V; obtain guaranteed PLC interface thresholds.
- An integral heat sink does not remove derating requirements. Above 40 °C, use the exact current-specific curve and provide clearance and airflow.
- Choose semiconductor fuses using the exact device I²t and fault-current conditions. Nonrepetitive surge current is not continuous or repetitive inrush capacity.
- Off-state leakage can energize the load. Provide an isolator and remove mains power before service; do not judge functionality using a continuity buzzer.
