MTL 8910-PS-DC Installation Guide Summary
Wiring Diagram Explanation
Terminal Block Configuration (Front Panel):
- Input Terminals (L/N/PE): Connect 100-240 VAC (L=Line, N=Neutral) or 120-370 VDC (L=Positive, N=Negative). PE (Protective Earth) must be grounded for safety.
- Output Terminals (+24V/0V): +24V (positive output) connects to instrument power input; 0V (common ground) connects to instrument ground terminal. Use twisted-pair cables for output wiring.
DC OK Relay Terminals (NO/NC/COM): NO (Normally Open) closes when output is stable; NC (Normally Closed) opens when output is stable. COM (Common) for relay circuit completion (for remote monitoring).
Note: Use 1.5-2.5 mm² copper wires for input/output connections. Torque terminal screws to 0.8-1.0 N·m. Avoid parallel wiring of multiple power supplies unless specified by the manufacturer.
Installation Precautions
Electrical Safety
- Disconnect input power before wiring or maintenance.
- Ensure input voltage matches the module’s rated range (AC/DC not mixed).
- Ground resistance must be ≤ 4 Ω for PE connection.
Mechanical Installation
- Mount on standard 35 mm DIN rail (EN 50022) in a vertical position.
- Leave ≥ 10 mm clearance on all sides for heat dissipation.
- Avoid installation near heat sources or corrosive gases.
Operation & Maintenance
- Check LED indicators after power-on: Green (Power OK) = normal operation.
- Do not exceed maximum output current (10 A) to prevent overload protection triggering.
- Clean the module surface periodically to avoid dust accumulation.
Environmental Requirements
- Operating temperature: -20°C to +60°C (no condensation).
- Relative humidity: 10% to 90% (non-condensing).
- Altitude: ≤ 2000 m above sea level (derate 1% per 100 m above 2000 m).
Quick Troubleshooting
| Symptom | Possible Cause | Solution |
|---|---|---|
| No Power OK LED | Input power missing or incorrect | Check input wiring and voltage; verify PE connection |
| Output voltage unstable | Overload or loose wiring | Reduce load to ≤10 A; re-tighten terminal screws |
| Module overheating | Insufficient clearance or high ambient temperature | Increase ventilation; move module to cooler location |
