Installation & Maintenance Guide
Installation Requirements:
- Snap the power supply unit onto a standard 35 mm DIN rail (NS 35, EN 60715) in a horizontal position.
- Maintain proper clearance: 5 mm horizontally from active components and 50 mm vertically above and below the unit for natural convection cooling.
- Wire the input line (85–264V AC or 90–350V DC) to the designated screw terminals, ensuring proper earth grounding (PE).
- Use suitable wire cross-sections (0.2 to 6 mm² solid / 0.2 to 4 mm² stranded, 7 mm stripping length) for input and output terminals.
Maintenance Tips:
- Regularly check terminal screw connections to ensure tight clamping against machine vibration.
- Keep top and bottom ventilation openings clean and free from dust, lint, or oil accumulation.
- Monitor front-panel diagnostic LEDs (“DC OK” green LED, “BOOST” yellow LED) during routine panel audits.
Safety Instructions:
- Disconnect all primary power sources before carrying out any mounting, wiring, or maintenance tasks.
- Installation must be conducted solely by qualified electrical personnel or automation engineers.
- Do not operate the IP20 unit outside an enclosed electrical panel in dusty or wet environments.
