- Hazardous Area Installation: FM-suffix models must comply with Class I/II/III, Div 2 wiring guidelines (proper grounding, approved cables)
- Conductor Sizing: Use recommended wire gauges (input: 6AWG~2AWG; output: 12AWG~6AWG) to avoid overheating
- Mounting: Ensure secure wall-mount/DIN rail installation; allow ≥10cm clearance for heat dissipation
- Load Balancing: Distribute loads evenly across phases for 3-phase models to prevent phase imbalance
- Maintenance Checks: Regularly inspect terminal connections, circuit breakers, and FM certification labels; replace damaged components promptly
