Installation & Operation Guidelines

• Mount vertically on standard DIN rail (EN60715) with minimum 50mm clearance above and below for proper convection cooling
• For optimal performance, maintain ambient temperature below 40°C (derate linearly by 2.5% per °C above 40°C to 50°C maximum)
• Use copper conductors only (14-18 AWG recommended) with proper strain relief on terminal connections
• Ensure proper grounding according to NEC/NFPA70 (North America) or IEC/EN60204-1 (international) standards
• Verify input voltage matches local supply before energizing (100-120V or 200-240V AC)
• Periodically check terminal tightness (recommended torque 0.5-0.6Nm) during routine maintenance
