Installation & Maintenance Guide
Installation Requirements:
- Mount vertically or horizontally on a flat wall or panel plate using standard screw fasteners.
- Maintain at least 50 mm clearance above and below the unit to permit natural air convection cooling.
- Wire the input line (100–240V AC) to the L and N screw terminals, ensuring proper earth grounding (PE connection).
- Verify that total load connected to the output terminals does not exceed 12.5 A continuous current.
Maintenance Tips:
- Periodically check terminal screw connections to ensure wires remain tightly fastened against operational vibration.
- Keep cooling vents free from excessive lint, dust, or oil film accumulation common in industrial environments.
- Use the front-facing potentiometer to trim voltage if long cable runs cause a voltage drop at terminal points.
Safety Instructions:
- Disconnect main AC input power before carrying out any wiring or panel maintenance.
- Installation must be performed by a qualified electrician or control system engineer.
- Do not expose the IP20 enclosure to direct water spray, high humidity, or conductive contaminants.
